    WSLP3921 andWSLP5931 Power Metal Strip resistors

    The surface-mount WSLP3921 and WSLP5931 Power Metal Strip resistors in 3921 and 5931 case sizes offer power ratings from 5W to 10W with low resistance values down to 0.0003Ω. The resistors incorporate a solid metal nickel-chrome or manganese-copper alloy resistive element with a TCR below 20 ppm/ºC. This results in a high-power resistor with an operating temperature range of -65 °C to +170°C. Prices for the WSLP3921 and WSLP5931 are $0.45 and $0.68 each/50,000, respectively.
