Vishay WSH2818 Series Power Metal Strip Resistors are surface-mount resistors with very low resistance. These come in a package measuring 0.280in by 0.180in by 0.032in. WSH2818 series resistors feature a proprietary construction with improved thermal management to enable a 5W power rating in a small package size that maintains the superior electrical performance of the power metal strip construction. This makes it easy for designers to incorporate the resistor in place of larger surface-mount components to realize significant board space savings and enable the manufacture of smaller, lighter-end products.
The device's surface-mount construction enhances flexibility in the design of smaller and more robust electronics. These resistors offer low inductance values (<5nH), excellent frequency response, and low thermal EMF. The WSH2818 resistors have an operating temperature range of 65°C to +170°C and are capable of higher temperature performance than devices built with thin film or thick film resistor technologies. Typical applications include current sensing and voltage division.
