WSR21R000FEA Description

Short technical summary and product information.

The Vishay Dale WSR21R000FEA is a Power Metal Strip® surface mount resistor designed for current sensing, voltage division, and pulse applications. It offers a resistance value of 1 Ohm with a tight tolerance of ±1% and a power rating of 2W at 70°C.

 

This resistor features a low temperature coefficient of ±75ppm/°C and operates across a wide temperature range of -65°C to 275°C. Its construction utilizes a solid metal nickel-chrome or manganese-copper alloy resistive element, providing excellent frequency response up to 50 MHz and very low inductance from 0.5 nH to 5 nH. The component is AEC-Q200 qualified, indicating its suitability for automotive applications.

 

Packaged in a 4527 (11070M) case size, the WSR21R000FEA is suitable for surface mounting with solder terminations. Its dimensions are 11.56mm in length and 6.98mm in width, with a height of 2.54mm. The resistor also offers anti-sulfur properties and is moisture resistant.
