Alpha Electronics (A VPG Brand) 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.
