VPG Foil Resistors - Outstanding Performance - Precise. Stable. Reliable.
Three premier brands that represent the VPG commitment to unparalleled precision, stability and reliability -- Vishay Foil Resistors, Alpha Electronics, and Powertron -- have united under VPG Foil Resistors to offer a comprehensive portfolio of world-class solutions. The unique VPG Bulk Metal® Foil technology outperforms all other resistor technologies and comes in a wide variety of configurations and packages designed to surpass the requirements of even the most demanding applications. VPG products serve medical, agricultural, transportation, industrial, avionics, military, and space applications.
Unlike thin film or wirewound resistors, Bulk Metal® Foil resistors owe their superior precision to the use of a special alloy foil, with a thickness of several microns, as the resistive element. Use of this metal foil as the resistance element provides superior performance not found in any other resistor technology. In particular the temperature coefficient of resistance (TCR) has been reduced to an unprecedented, extremely low level of 0.14 ppm/°C thanks to strict quality control of the alloy composition and a newly developed foil stabilization treatment technology.
In addition to being a VPG distributor, Charcroft are also a VPG-Approved Precision Centre, manufacturing and delivering 0.005%+ radial and 0.01%+ surface mount resistors based on VPG’s Bulk Metal® Foil resistor technology. We also manufacture BS and CECC approved, and commercial multilayer ceramic capacitors (MLCCs) down to 1% tolerance. COTS and CECC-release precision resistors are available with optional Precision Express delivery of 5 to 15 days. All Precision Express products can be mounted on "Any-Quantity" tape-and-reels or bandoliers.
