POWER METAL STRIP ® RESISTORS Vishay Dale Power Metal Strip ® Surface-Mount Resistors INTRODUCTION 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 0.0002 Ω to 1 Ω. These patented, state-of-the-art products deliver overload capabilities equivalent to wirewound devices and temperature coefficients as low as 30 ppm/°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. KEY BENEFITS • • • • • • • Wide range of package sizes (0603 to 5931) Wide resistance range (0.0002 Ω to 1 Ω) High-temperature performance (up to 275 ºC) Tight tolerances (down to ± 0.1 %) Low temperature coefficients (down to ± 30 ppm/ºC) Excellent overload capability (equivalent to wirewound) Automotive Grade qualified RESOURCES • For technical questions contact [email protected] • Sales Contacts: http://www.vishay.com/doc?99914 A WORLD OF SOLUTIONS SELECTOR GUIDE 1/5 THIS DOCUMENT IS SUBJECT TO CHANGE WITHOUT NOTICE.
