Vishay High Temp Resistors

High-Temperature Products

Vishay offers high-temperature resistors, capacitors, inductors, and semiconductors. In oil and gas drilling, the instrumentation is exposed to harsh environments, including extreme temperatures, pressure, moisture, shock, and vibration. Once commissioned, the instrumentation must be relied upon to function for 5 to 10 years, and be powered at very high temperatures with no maintenance. The components used for this instrumentation must be able to withstand these harsh conditions while maintaining accuracy. Failure of the data would necessitate its removal for repairs, causing costly delays. Vishay helps to avoid this possibility by offering several high-reliability and high-precision resistors, capacitors, inductors, and semiconductors.

WSR SMD High Power Metal Strip® Resistors

Vishay / Dale WSR Power Metal Strip^® Resistors, are surface-mount devices that provide high power ratings up to 5W and low resistance values down to 0.001Ω. The series is ideally suited for a variety of current sensing, voltage division, and pulse applications, including switching and linear power supplies, instruments, and power amplifiers. Vishay / Dale WSR Power Metal Strip Resistors feature all-welded construction and a solid metal nickel-chrome or manganese-copper alloy resistive element with low TCR (<20ppm/°C). The series offers solderable terminations, very low inductance (0.5nH to 5nH), excellent frequency response to 50MHz, and low thermal EMF (<3µV/°C), as well as RoHS compliance.

WSR5 Power Metal Strip® Resistors

Vishay / Dale has expanded the WSR Series Power Metal Strip® Resistors. The WSR5 resistors are high power (5 W), low value (down to 0.001Ω), surface mount resistors that are ideal for all types of current sensing, voltage division, and pulse applications including switching and linear power supplies, instruments, and power amplifiers. The integral heat sink is not utilized for resistance values less than 0.0075Ω. The WSR5 series is available in 4527 EIA case size with a small footprint of L .455", W .275", H .095. Improved thermal management is incorporated into the all-welded, molded high temperature encapsulation, Lead-free construction of solid metal Nickel-Chrome or Manganese-Copper alloy resistive element with low TCR (<20 ppm/ºC). The Vishay / Dale WSR5 Power Metal Strip Resistors feature very low inductance (<5 nH), low thermal EMF (<3 µV/ºC), and excellent frequency response to 50 MHz. Compliant to RoHS directive 2002/95/EC.

Current Sensing Resistors

Vishay / Dale Current Sensing Resistors are SMT, fixed, discrete resistors available in a wide range of package sizes. These resistors feature low resistance values, a variety of temperature performances, and a range of temperature coefficients.  The surface mount Vishay / Dale current sensing resistors offer tight tolerances, excellent overload capabilities (equivalent to wirewound), and are ideal for high-current and high-power applications.
