Vishay – Power Metal Strip® Resistors, Low Value (Down to 0.0003Ω), Surface Mount


Vishay_Logo_BlueBlack_CMYK    NPI_LOGO
Vishay’s Power Metal Strip current sensing resistors combine superior performance in high temperature applications with a wide range of package sizes and a choice of resistance values from 0.0002Ω to 1Ω. These patented, state-of-the-art products deliver
overload capabilities equivalent to wirewound devices and temperature coefficients as low as 30ppm/°C.

Current sensing Power Metal Strip resistors allow control circuitry to monitor the level of current in a circuit by translating current into a voltage that can be monitored easily. The devices work by resisting the current flow in a circuit to a
calibrated level, thus allowing a voltage drop to be detected and monitored by control circuitry. The low resistance values of Power Metal Strip resistors allow this function to be carried out with exceptional efficiency.
