Part Numbering Example
JER1206F1R500(L): JER Series, 1206 Size, 1W Rated Power, 1% Tolerance, 500m Resistance.
Marking Code Examples
Resistance Code: R50m = 0.5m, R001 = 1m, 1R5m = 1.5m, R002 = 2m, R500 = 500m
Electrical Characteristics
Operating Temperature Range: -55 to +170.
Power Derating: Maximum load power should be reduced when operating in ambient environments above 70, as per the power attenuation curve.
Rated Current Calculation: I = P/R (where I is rated current, P is rated power, R is resistance). If calculated current exceeds the maximum working current for the type, the maximum working current shall be considered the rated current.
