Note: Temperature rise data are given here for typical mounting conditions. Actual figures depend on PCB copper weight, mounting pad size, track
width and substrate type. Also, the open air format responds better to forced air cooling than chip format resistors. For values below 5 milliohms
allowance should be made for heat generated in the copper tracks themselves. Application-specific guidance is available on request.

Note: For OARS-1Z the above derating graph may be applied to
the square of the current rating.
Note: This graph relates to single pulses of short duration (≤ 100ms).
Higher energy limits apply for longer pulses and overloads
