STANDARD ELECTRICAL SPECIFICATIONS

• Ask about further value ranges, tighter tolerances and TCR’s.

• Power rating depends on the max. temperature at the solder point, the component placement density and the substrate material

• 4-Digit Marking, according to MIL-PRF-55342 (except as noted in Ordering Information table), on top side
