Angstrohm / Vishay

The Vishay Angstrohm product portfolio consists of Military and Industrial axial-leaded hermetic metal film resistors. These hermetically sealed resistors are moisture-proof and ideal for use in hostile environments. They feature a true glass-to-metal hermetic enclosure that seals the resistor element in an inert gas atmosphere and protects it from virtually all adverse environmental influences. Due to the high reliability and stability characteristics of Vishay Angstrohm resistors, they are used extensively in military, missile, aerospace and other applications where resistance to hostile environments is a critical parameter. Vishay Angstrohm resistors continue to be qualified to MIL-PRF-55182, characteristics C and E.

The Vishay Angstrohm portfolio of products is made up of hermetic metal film resistors and power rheostats. The hermetically sealed resistors are moisture-proof and ideal for use in hostile environments.

Due to the high reliability and stability characteristics of Vishay Angstrohm resistors, they are used extensively in military, missile, and aerospace applications where resistance to hostile environments is a critical parameter. Vishay Angstrohm rheostats provide resistance or ratio adjustments for optimizing circuit performance.

The Vishay Angstrohm brand name was also previously associated with Power Rheostat products. The Rheostat product group was sold by Vishay to Ohmite.

Rolling Meadows, Illinois – January, 2007 – Ohmite Manufacturing Company announced today that they have acquired both the Ultronix Precision Wirewound Resistor and Angstrohm Rheostat Businesses of Vishay Intertechnology, Inc. Ultronix is a Pennsylvania-based manufacturer of precision wirewound resistors. Angstrohm, based in Hagerstown, MD, is a manufacturer of wirewound rheostats.

Angstrohm, also known as Angstrohm Precision, was a renowned manufacturer of high-quality resistors. The company was founded by Arnold O. Beckman in 1936 and was based in Pasadena, California, USA. Angstrohm Resistors gained a reputation for producing precision resistors with exceptional performance and reliability.

Angstrohm Resistors:
