【文字介绍】

The advanced construction of the WSHM2818 resistor incorporates improved thermal management and a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (< 20 ppm/ºC). This results in a high-power resistor in the 2818 package size that maintains the superior electrical characteristics and performance of the Power Metal Strip construction such as excellent 1000 h load life stability and very good resistance to short time overload of < ± 1 %. The device's high power-to-footprint-size ratio allows designers to save board space and create smaller end products by replacing larger resistors with similar power capability and multiple devices with lower power ratings.
