Marking Code Examples
R50m=0.5m, R001=1m, R010=10m, R200=200m, R500=500m
Power Derating & Rated Current
Maximum load power should be reduced when operating in ambient temperatures above 70C, as per the power derating curve. Rated current (I) is calculated by I = P/R, where P is rated power and R is resistance. If the calculated current exceeds the maximum working current for the type, the maximum working current applies.
