Dissipation Factor at 1kHz vs. Temperature

Specification Summary

Characteristics

Dielectric Strength

Capacitors withstand a DC potential of 1.3 x rated

voltage for one (1) minute without damage or break-

down. Test voltage is applied and discharged through

a minimum resistance of 100 OHM per volt minimum.

Dissipation Factor

Polypropylene has an intrinsic dissipation factor of

less than 2.1x 10-4 over the operating temperature

range of -55°C to +105°C and frequencies to 1MHz.

Capacitance Range

6.5μF to 300.0μF

Capacitance Tolerance

Standard capacitance tolerance is ±10%.
Tolerances of ±5% and ±20% are also available.

Operating Temperature Range

-55°C to +105°C

Enclosure/Construction

Unlytic polypropylene potted in a thermoplastic housing. Terminals
are tin plated brass.

Voltage Rating

500 VDC to 2200 VDC

Quality Control

Capacitors are tested 100% for:

• Capacitance

• Tolerance

• Dissipation Factor

• Dielectric withstanding voltage

• Insulation Resistance

• Equivalent Series Resistance (ESR)

Process and inspection data are maintained on file and available

upon special request.

DC Voltage Rating: Q = 500 VDC, K = 600, etc.

CAPACITANCE IN PICOFARADS

The first two digits are significant, the third represents the number of zeros

(e.g 157=150,000,000pF)

Marking And Date Code

All capacitors are marked with company initials "EC", corporate logo or EC trademark—in addition to type UL3, capacitance, tolerance, rated

DC working voltage and date code. The first two digits of the date code represent the year, the second two digits the week, i.e., 1252 is the

52nd week of 2012, 1202 is the second week of 2012.

Quality Assurance

Major emphasis is placed on quality assurance. EC is an ISO 9001 and AS9100 Certified Company. Raw material inspection and the use of

SPC manufacturing procedures assure the highest quality standards. Procedures are fully described in the EC Quality Control Manual.

Electronic Concepts will continue to advance the state-of-the-art by utilizing leading edge technology, compact capacitor designs and

establishing reliability procedures.

The UNLYTIC

UL3 SERIES, with its introduction, the designer has a film capacitor for high power filter systems that will

maximize space utilization, performance and reliability. With the added potential for measurable production cost savings.

The combination of physical and electrical properties it offers encompasses low inductance with high current carrying

capability – and a low profile to make the most efficient use of system space and increased cooling efficiency. Plus an

in-house developed, “specific to the task” thermoplastic formulation for the enclosure, improves thermal conductivity. There

is also an integrated flange with pre-drilled holes to simplify mounting.
