Vishay's Power Metal Strip Resistors in 3921 and 5931 Case Sizes Feature High Power Ratings From 5 W to 10 W and Extremely Low Resistance Values Down to 0.0003 Ω
Vishay Intertechnology, Inc. (NYSE: VSH) today announced two new surface-mount Power Metal Strip® resistors in the 3921 and 5931 case sizes that combine high power ratings from 5 W to 10 W with extremely low resistance values.The
The new devices allow for the design of high-power circuits featuring the smallest possible resistor for higher-performance end products. Furthermore, the resistors' high-temperature capability allows the use of the WSLP3921 and WSLP5931 in harsh, high-temperature environments without sacrificing power rating or electrical performance.
The resistors are ideal for all types of current sensing, voltage division, and pulse applications, including switching and linear power supplies, instruments, and power amplifiers in automotive electronic controls such as engine, antilock brakes, and climate controls; industrial controls, including down-hole test/measurement equipment for oil/gas well drilling; and inverter controls for HVAC systems.
The WSLP3921 resistor measures 0.394 in. by 0.205 in. [10.0 mm by 5.2 mm] with a maximum height profile of 0.020 in. [0.5 mm], while the WSLP5931 measures 0.591 in. by 0.305 in. [15.0 mm by 7.75 mm] with a height profile of 0.020 in. [0.5 mm]. A proprietary processing technique produces extremely low resistance values ranging from 0.0003 Ω to 0.004 Ω, with tight tolerances of 1.0 % and 5.0 %.
Like all Power Metal Strip resistors, the devices released today feature an all-welded construction that contributes to their superior electrical performance. The WSLP3921 and WSLP5931 provide very low inductance of 0.5 ηH to 5 ηH and low thermal EMF (< 3 μV/°C).
