Absolute Maximum Ratings & Characteristics

Note1: For a zero ohm resistor, it is similar to a 1/4W resistor(1/8W size also available,typical

resistance 0.004 Ω.

Power derating curve

For resistors operate in the ambient temperature over 70˚C, loading power ratio will derate in accordance

with following curve.
