VISHAY WSL Series 0.25Ω Metal Strip Resistor, 1W, 2512, ±1%
High-stability metal strip resistor, 0.25Ω, ±1%, 1W, AEC-Q200 qualified. Ideal for current sensing and power supplies.
The VISHAY WSL Series Metal Strip® Resistor is a high-performance surface mount current sense resistor, offering a low resistance value of 0.25Ω in a compact 2512 (6432 metric) chip format. With a power rating of 1W and a tight resistance tolerance of ±1%, this resistor is designed for precise current sensing and voltage division in demanding electronic circuits.
Utilising a solid metal nickel-chrome or manganese-copper alloy resistive element, the WSL2512R2500FEA delivers exceptional stability and reliability. It features a low temperature coefficient of just ±75ppm/°C, ensuring accurate performance across a wide operating temperature range from -65°C to 170°C. The component also boasts excellent frequency response up to 50MHz and low thermal EMF (less than 3µV/°C), making it ideal for high-frequency applications.
This resistor is AEC-Q200 qualified, confirming its suitability for automotive and harsh environment applications. Its solderable terminations ensure reliable connection, while the low inductance of 0.5 to 5nH minimises signal distortion. Whether used in switching power supplies, power amplifiers, or instrumentation, this metal strip resistor delivers consistent and accurate performance.
