Vishay Power Metal Strip resistor

Vishay Intertechnology has released a surface-mount Power Metal Strip resistor in a 2512 case size that combines high power capacity of 3 W with low resistance values down to 0.0005 Ω.

The construction of the resistor incorporates a solid metal, nickel-chrome or manganese-copper alloy resistive element with low TCR (< 20 PPM/°C) and specially selected and stabilised material.

This results in a high power resistor with an operating temperature range of -65 to 170°C, while maintaining the electrical characteristics of the Power Metal Strip construction.

The devices allow for the design of high power circuits featuring the smallest possible resistor. The resistors' high temperature capability allows their use in harsh, high temperature environments.

The resistors are suitable for all types of current sensing and pulse applications including: switching and linear power supplies, instruments, power amplifiers and shunts in motor vehicle electronic controls such as engine, anti-lock brake and climate controls; industrial controls including: down-hole test/measurement equipment for oil/gas well drilling; and consumer product controls such as inverter controls for HVAC systems.
