Product Description

Solder Resistance Alloy Resistor, 4-terminal chip package for current detection, ultra-low resistance (as low as 0.0005R), high stability, and passed AEC-Q200 automotive-grade reliability test.
 

FEATURES:

1,Electronic beam welded alloy resistors, 4-terminal structure, pure copper electrodes, are ideal solutions for current detection applications.

2,The product has good consistency, reliability, stability, high resistance to pulse, and supports a tolerance of ±0.5%.

3,Special welding process, all-metal structure, supports low resistance (as low as 0.0005R).

4,High-temperature resistant resin molded encapsulation, strong resistance to weathering.

5,Extremely low thermal voltage (<1 uV/C).

6,Ultra-low parasitic inductance (0.5nH to 3nH), fast response, suitable for high-frequency AC current detection.

7,Passed AEC-Q200 automotive-grade reliability test.

8,Comply with RoHS and other environmental requirements.
