SCOPE

1.1

This specification is applicable to lead and halogen free CR series precision thick film chip
resistors.

1.2

Lead free products mean lead free termination meets RoHS requirement. Pb contained in
glass material of resistor element is exempted by RoHS directive.

1.3

The products for 0402, 0603, 0805, 1206, 1210, 2010 and 2512 are tested and passed
based on the test conditions and methods defined in AEC-Q200.

Rated Voltage

The rated voltage is calculated from the rated power and nominal resistance by the
following formula:

___

E =



P.R

Where E : Rated Voltage (V)

P : Rated Power (W)
R : Nominal Resistance (



)

In case the value calculated by the formula exceeds the maximum working voltage given in
Section 3.1.2, the maximum working voltage in Section 3.1.2 shall be regarded as the rated
voltage.
