New WSLT2512 1-W Surface-Mount Power Metal Strip® Resistor

The Key Benefits:
 Temperature range up to +275 °C allows for use in harsh environments
 Save space and replace larger resistors with a very small 2512 case size
 Proprietary manufacturing techniques result in a very low 10-mΩ to 500-mΩ resistance value range
 Durable with all-welded construction and a solid metal nickel-chrome alloy resistive element
 Lead (Pb)-free construction is RoHS-compliant

 Current sensing, voltage division, and pulse applications in automotive engine controls, safety controls, multi-media electronics, climate controls, and anti-lock brakes; and industrial oil/gas well drilling, including down hole test/measurement equipment

The News:

Vishay’s New WSLT2512 1-W Surface-Mount 2512 Power Metal Strip® Resistor Is Industry’s First to Offer Temperature Range of –65 °C to +275 °C
Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new high-temperature 1-W surface-mount Power Metal Strip® resistor that is the industry’s first current sensing resistor in the 2512 case size to operate in a temperature range of –65 °C to +275 °C. The WSLT2512 resistor features a very low 10-mΩ to 500-mΩ resistance value range, a tight tolerance down to ±0.5 %, and low RTC values down to ±75 ppm/°C.

 The temperature range and small case size of the resistor allow it to replace larger current sensing resistors
 Robust specifications allow it to be used in harsh environments without sacrificing power rating or electrical performance
 Manufactured using proprietary techniques that result in extremely low resistance values

Key Device Specifications:
 Temperature range of –65 °C to +275 °C
 Very low 10-mΩ to 500-mΩ resistance value range
 Tight tolerance down to ±0.5 %
 Low RTC values down to ±75 ppm/°C
 All-welded construction with a solid metal nickel-chrome alloy resistive element µH
 Excellent frequency response to 50 MHz
 Low thermal EMF of less than 3μV/°C

The Perspective: Vishay’s new WSLT2512 high-temperature 1-W surface-mount Power Metal Strip® resistor is the industry’s first current sensing resistor in the 2512 case size to operate in a temperature range of –65 °C to +275 °C. The device’s temperature range allows it to replace larger current sensing resistors, and its rugged specifications are optimized for a variety of applications in harsh environments without sacrificing power rating or electrical performance.

Availability: Samples and production quantities of the new resistor are available now, with a lead time of four to six weeks for larger orders.
