Physical Data

IRC’s PFC chip resistors are available with MIL screening. These chips are manufactured on the same production line as our Mil-

qualified chip resistors and screened in accordance with MIL-PRF-55342.

These chips are identified with IRC’s ordering information and not with MIL marking.

Marking

The 0402 chips are not marked. 3 digit marking is used on the 0603 size and 4 digit marking on larger sizes and E96 values.

Special Variants

For PFC resistors with tighter tolerances, SnPb terminations or MIL screening, refer to the separate PFC Special Series datasheet.

Construction

Conductors and tantalum nitride resistive element are applied to an alumina substrate. The product is laser trimmed to value, and a

protective black epoxy coat is applied. The product is then metallized and plated to provide a wrap-around solderable termination with

a 100% matte tin finish on a nickel barrier layer. It is 100% tested and provided on standard paper carrier tape.
