The PATCH RESISTOR is a pure alloy high-power current sensing resistor designed for surface mount applications. It offers ultra-low resistance values (as low as 0.0R) and high power handling capabilities up to 3W, making it ideal for precise current detection in demanding environments. It is AEC-Q200 compliant and meets RoHS and REACH certifications.

Refer to the provided list for resistance value to code mapping (e.g., R020 = 20m, 1R5m = 1.5m).
Maximum load power should be reduced when operating in ambient temperatures above 70C, as indicated by the power attenuation curve.
I = P/R (where I is rated current in A, P is rated power in W, and R is resistance in ohms). If the calculated current exceeds the model's maximum working current, the latter applies.
