New 3-Watt Surface Mount Wirewound Resistor Provides Enhanced Stability Under Harsh Environmental Conditions With the Industry's Highest Derating Temperature

MALVERN, PENNSYLVANIA-May 18, 2001-A new molded wirewound resistor providing the industry's highest derating temperature was announced today by Vishay Intertechnology, Inc. (NYSE: VSH). Featuring a highly durable, surface mount design, the new Vishay Dale WSC6927 is ideal for use as a power supply bleeder resistor or series dropping resistor in pulsing applications and voltage divider circuits. These applications are commonly found in automobile electronic controls, satellite receivers, instrumentation, home entertainment products, and fixed telecommunications systems.

With a molded thermoplastic encapsulation, the WSC6927 offers a 3 W power rating at 70°C, and derates linearly to 275°C. The new device extends the derating temperature by as much as 77% compared to competing devices currently on the market, which results in higher-power operation at elevated temperatures. The resistor additionally provides a resistance range of 0.1Ω to 2.6kΩ, and features tolerance options of ±0.5%, ±1%, and ±5%.

Vishay's WSC6927 wirewound resistor measures 17.53mm by 6.98mm, with a 7.11mm height profile (0.69" by 0.28" by 0.275"). As a surface mount device, it can be used to replace 3 W axial leaded components, enabling automatic, high-speed assembly. The resistor also features compliant terminations that eliminate the risk of solder fillet cracking.

The WSC6927's unique combination of high temperature performance and a surface mount package provides manufacturers with a reliable, high performance device that streamlines production costs and labor-which in turn means savings for the end-system user.      

Vishay also offers a non-inductive Aryton-Perry wound resistor style. The WSN6927 features a resistance range of 0.1Ω to 1.3kΩ and is identical to the WSC6927 in size and environmental characteristics.
