High Frequency Power Ceramic Capacitors

General Description

The high frequency power ceramic capacitors are designed

for use in circuits that are subject to high frequency, high

power applications or to DC or AC (commercial frequency)

high voltage.

Typical applications are:

1. Oscillating circuits, resonance circuits, bypass capacitors,

and coupling capacitors in various types of high

frequency induction and dielectric heating equipment

2. Transmission line carrier coupling capacitors

3. Capacitors for capacitance voltage dividers

This type of capacitor is especially indispensable for

equipment handling high frequency power. In recent

years, with the spread of high frequency application

technology, the high frequency power ceramic capacitors

are finding expanded applications.

Features

The outstanding features of our high frequency power

ceramic capacitors are the result of our many years of

manufacturing experience and the use of new technologies.

1. Small size and high capacitance

2. Linear and reversible temperature characteristic

3. Higher operating temperature ranges than other capacitors

4. High "Q" from low frequency to high frequency

5. Outstanding resistance to humidity and heat

Virtually no performance deterioration after extended use.

6. Excellent high frequency operation due to small internal

inductance

Power Capacity of Capacitors

The permissible apparent power through a ceramic

capacitor is limited by the working voltage of the capacitor in

the lower frequency region and by the permissible

temperature rise in the higher frequency region.

1. Power Capacity in the Lower Frequency Region

Every capacitor has a rated working voltage at which safe

operation is guaranteed within a specified operating

temperature range, because the applied voltage is

generally limited by the specified rated voltage at low

frequency, the apparent power which can be introduced

into the capacitor is consequently limited.

Assume the capacitance as C, DC voltage applied to the

ceramic capacitor having a rated DC voltage E

high frequency voltage

(effective value) that can be

superimposed is given by the following formula:

Therefore, at frequency f, the apparent power W

that can

be introduced into the capacitor is:

· 2

f · C

)

· 2

f · C

= (E

)

f · C

The apparent power is proportional to the frequency f

when E

and

are constant.

The maximum current that flows through the capacitor is

given by:

i = 2

f · C ·

= 2

f · C ·

= 2

f · C · (E

High Frequency Power Ceramic Capacitors

2. Power Capacity in the Higher Frequency Region

The allowable power of the ceramic capacitor in the

higher frequency region is generally limited by heating

due to dielectric losses and temperature rise caused by

heating, due to Joule heat at areas where the terminals

are connected to the electrodes.

Thus, the permissible power at high frequencies is limited

by the allowable internal temperature rise. The

permissible power is increased as the internal

temperature rises.

For example, when a high frequency voltage of frequency

f is applied to a capacitor of capacitance C, the heat

generated from dielectric loss is expressed by:

= DF · W

= DF · 2

f · C · e

= DF ·

. . . . . . . . . . . . . . . . (1)

C · 2

: Apparent power passing through the capacitor

: Applied high frequency voltage (Effective value)

: High frequency current

: High frequency resistance at the electrodes and

connecting terminals

The heating due to Joule heat at areas where electrodes

and terminals join is given by:

= R · i

= R · i · 2

f · C ·

= R · 2

f · C · W

. . . . . . . . . . . . . . . (2)

Thus, the total calorific value is expressed by:

= W

+ W

= DF · W

+ R · 2

f · C · W

The total calorific value W

is made up of a term in which

the value is independent of frequency when W

constant, and a second term in which the value is

proportional to frequency.

(This is based on the assumption that DF and R remain

constant independent of f.)

Thus, the value in the second term is small when the

frequency is relatively low; the first term becomes

dominant.

As a result, the calorific value becomes proportional to

the apparent power W

which passes through the

capacitor independent of frequency.

At high frequencies, on the other hand, the second term

becomes dominant, and W

becomes proportional to W

and frequency.

When W

is maintained at a constant value, therefore, the

power capacity W

that can be passed through the

capacitor remains constant independent of frequency at

relatively low frequencies, while at high frequencies, W

decreases, being inversely proportional to frequency.

Critical frequencies f

and f

vary with the shape,

operating voltage, capacitance, etc. of a capacitor but f

ranges from 200kHz to 2MHz and f

, from 2MHz to

20MHz.

Caution (Rating)

1. Operating Voltage

When DC-rated capacitors are to be used in AC or ripple

current circuits, be sure to maintain the Vp-p value of the

applied voltage or the Vo-p which contains DC bias within

the rated voltage range.

When the voltage is applied to the circuit, starting or

stopping may generate irregular voltage for a transit

period because of resonance or switching. Be sure to

use a capacitor with a rated voltage range that includes

these irregular voltages.

2. Operating Temperature and Self-generated Heat

Keep the surface temperature of a capacitor below the

upper limit of its rated operating temperature range. Be

sure to take into account the heat generated by the

capacitor itself. When the capacitor is used in a high

frequency current, it may self-generate heat due to

dielectric loss. The applied voltage load should be such

that the capacitor's self-generated heat is within 10°C (in

case of temperature characteristic F and within 20°C) at

an atmosphere temperature of 25°C. Excessive heat may

lead to deterioration of the capacitor's characteristics and

reliability. (Never attempt to perform measurement with

the cooling fan running. Otherwise, accurate

measurement cannot be ensured.)

Caution (Storage and Operation Condition)

Operating and storage environment

The insulating coating of capacitors does not form a

perfect seal; therefore, do not use or store capacitors in a

corrosive atmosphere, especially where chloride gas,

sulfide gas, acid, alkali, salt or the like are present. And

avoid exposure to moisture.

Avoid a dusty place. Otherwise, surface corona discharge

and flashover may occur.

Store the capacitors where the temperature and relative

humidity do not exceed -10 to 40 degrees centigrade and

15 to 85%. Use capacitors within 6 months.

Caution/Notice

Caution (Soldering and Mounting)

1. Installation (Except for DC5 Series/Shape code: C1, C3)

Installation torque should not exceed the torque strength

values in "Specifications and Test Methods".

Do not use a screw with a thread depth greater than

specified.

Avoid installation in which any bending torque is applied

to the capacitor terminal.

Do not fix the product body with only one terminal. (Avoid

cantilever mounting.) Do not rework or solder the

terminals.

2. Soldering (DC5 Series/Shape code: C1, C3)

When soldering this product to a PCB/PWB, do not

exceed the solder heat resistance specification of the

capacitor. Subjecting this product to excessive heating

could melt the internal junction solder and may result in

thermal shocks that can crack the ceramic element.

When soldering capacitor with a soldering iron, it should

be performed in following conditions.

Soldering method: Soldering iron

Soldering temperature: 270°C max.

Soldering time: 3 sec. max.

*Solder the lead terminals at 3mm or longer distance

from their roots.

Caution (Handling)

Vibration and impact

Since this product is made of ceramics, applying impact

(drop impact, etc.) to the product results in breakage or

flaws of elements. Do not transport the product with the

product being mounted to the set.

Otherwise, the terminal strength may be deteriorated due

to impact or vibration.

FAILURE TO FOLLOW THE ABOVE CAUTIONS MAY

RESULT, WORST CASE, IN A SHORT CIRCUIT AND

CAUSE FUMING OR PARTIAL DISPERSION WHEN THE

PRODUCT IS USED.

Notice (Rating)

Capacitance change of capacitor

1. Class 1 capacitors

Capacitance might change a little depending on the

surrounding temperature or an applied voltage.

Please contact us if you intend to use this product in a

strict time constant circuit.

2. Class 2 and 3 capacitors

Class 2 and 3 capacitors with temperature characteristics

B, E and F have an aging characteristic, whereby the

capacitor continually decreases its capacitance slightly if

the capacitor is left on for a long time. Moreover,

capacitance might change greatly depending on the

surrounding temperature or an applied voltage. So, it is

not likely to be suitable for use in a time constant circuit.

Please contact us if you need detailed information.
