Surface mount resistors for current detection SRS, SRL, SRE, SRM, SRF
SRS・SRL・SRE・SRM・SRF
It is a resistor with good mountability and excellent shock resistance.
It is used for purposes such as current and voltage control, overcurrent limit monitoring, and battery level detection. It is a resistor that is optimal for current detection due to its low resistance value and has excellent resistance temperature characteristics. Additionally, it has low residual inductance and excellent high-frequency characteristics.
