Power Metal Film

Resistor

Application Notes

1. If the resistors are to dissipate full rate power, it

is recommended that the terminations should not be

soldered closer than 4mm from the body.

2. Due to operating temperature limitations imposed

by some pcb materials, derating may be necessary. An

estimate of the temperature rise to be expected can be

calculated using the thermal impedance figures given

under Electrical Data.

3. Lead formed resistors can also be supplied. Standard

options of Lancet, Radial, and Goalpost forming are

shown in lead Form Information section.
