Full Electric Vehicle Components

Vishay Full Electric Vehicle (FEV) components are unique automotive component solutions for converters and boosters, battery management, and chargers.

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.

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.

Resistori Power Metal Strip® WSR Vishay/Dale

I resistori Power Metal Strip® WSR Vishay / Dale sono resistori a montaggio superficiale con elevati valori nominali di potenza fino a 5 W e basso valore (fino ad appena 0,001 Ω). La serie WSR è ideale per tutti i tipi di applicazioni di rilevamento di corrente, ripartizione della tensione e a impulsi, inclusi alimentatori a commutazione e lineari, strumenti e amplificatori di potenza. Con una costruzione interamente saldata e un elemento resistivo in metallo solido di nichel-cromo o manganese-rame con basso TCR (<20 ppm/ºC), i resistori Power Metal Strip WSR Vishay/Dale presentano terminazioni saldabili, induttanza molto ridotta (da 0,5 nH a 5 nH), ottima risposta in frequenza a 50 MHz e bassa EMF termica (< 3 µV/ºC), nonché conformità alla direttiva RoHS 2002/95/CE.
WSR5 - potenza nominale 5 W
WSR3 - potenza nominale 3 W
WSR2 - potenza nominale 2 W
