Power Derating Curve
When the resistor is operating in an ambient environment above 70 C, the maximum load power should be reduced according to the curve.
Rated Current Calculation
I = P/R (I: Rated current (A), P: Rated Power (W), R: Resistance (ohm)). If the calculated current exceeds the maximum working current for the type, the maximum working current shall be regarded as the rated current.
Marking on Resistor Body
Resistance Code examples: R50m=0.5m, R001=1m, R010=10m, R200=200m, R500=500m
Peel Force of Top Cover Tape
Paper carrier tape: 0.1N to 0.7N (10 to 70 g). Plastic carrier tape: 0.3N to 1N (30 to 100 g) at a speed of 300 mm/min and an angle of 165 to 180 degrees.
