Vishay Foil Resistors – Brands

Vishay Foil Resistors. Alpha Electronics. Powertron.

VPG Foil Resistors' brands are globally known for consistently delivering unparalleled precision, stability and reliability. Employing and refining our unique Bulk Metal® Foil technology since 1962, our ultra-precision technology consistently outperforms all other resistor technologies, resulting in a track record as the solution of choice over other options. We also offer the expertise and resources to deliver a completely customized solution for any application.

Vishay Foil Resistors

Vishay Foil Resistors' Bulk Metal® Foil resistors provide extremely low temperature coefficient of resistance (TCR) and exceptional long-term stability through temperature extremes. The Vishay Foil Resistors portfolio includes discrete resistors and resistor networks in surface-mount and through-hole (leaded) configurations, precision trimming potentiometers, and discrete chips for use in hybrid circuits, with customized chip resistor networks and arrays available. We continue to develop, manufacture, and market new types of Bulk Metal® Foil resistors, including military-established-reliability components (EEE-INST-002, DLA, CECC, ESA, ER, QPL, etc).

Alpha Electronics

Alpha Electronics has been supplying ultra-precision Bulk Metal® Foil resistors to engineers from Japan with “Stability, Accuracy, and Reliability” since 1978. The resistance stability of Alpha foil resistor technology against changes in temperature and over time makes the devices excellent metrological standard resistors as well. Without needing the oil baths required by conventional standard resistors, they are a popular choice by national standard institutes and local calibration laboratories for primary and secondary standards. Alpha’s standard resistors are available in a variety of models to fit a wide range of applications. Our ultra-precision thermosensitive resistor features a resistivity that varies linearly with temperature change, and is ideally designed for temperature detection and compensation applications with small size and rapid response.
