5 W current sensing resistors
11 November 2009, Passive Components

Vishay has expanded its WSR series of Power Metal Strip resistors with the first such device to offer a 5 W power rating in the 4527 package size. Like the WSR2 (2 W) and WSR3 (3 W), the new WSR5 measures just 11,56 mm by 6,98 mm with a height profile of 2,41 mm, making it a compact solution for electronic controls in automotive systems, power supplies in communications base stations, and DC-DC converters and VRMs in high-end workstations and servers.

A proprietary processing technique allows the WSR5 to offer low resistance values ranging from 1 m to 300 m in a standard resistance tolerance of ±1%. A tolerance of ±0,5% is available for the resistance range of 10 m to 300 m. The WSR5’s low inductance values range from 0,5 nH to 5 nH, and the device’s temperature coefficients are ±110 ppm/°C for the 7,5 m to 9,9 m range and ±75 ppm/°C for the 10 m to 300 m range.

The resistor’s proprietary construction features a moulded, high-temperature encapsulation with an integrated heatsink for improved thermal management. As a result, it maintains the good electrical characteristics of the Power Metal Strip construction during operation in a variety of high-current applications. Low thermal EMF, a broad operating temperature range of -65°C to +275°C, and resistance to moisture, vibration, thermal and mechanical shock ensure reliable operation. The WSR5’s proprietary Power Metal Strip design features all-welded construction, solderable terminations and a solid metal alloy resistive element.
