VPG’s Extreme Pressure-Cooker Test Highlights Stability, Robustness of Hermetically Sealed Bulk Metal® Foil Resistors
MALVERN, PENNSYLVANIA — June 05, 2012 — Vishay Precision Group, Inc. (NYSE: VPG) today announced that its Vishay Foil Resistors (VFR) brand has unveiled a new video highlighting the stability of hermetically sealed Bulk Metal® Foil resistors. The short video demonstrates how VFR’s VHP100 resistor experiences no change in resistance after being immersed in 100% humidity under high pressure within a pressure cooker for one hour.
VFR’s hermetically sealed foil resistors not only prevent moisture incursions, but they maintain their hermeticity under extreme conditions to hold their original resistance value after exposure to high temperatures as well as humidity.
In the video demonstration introduced today, the resistance of a VFR 10 kΩ VHP100 hermetically sealed resistor is measured at room temperature (+70°F/21°C). The resistor is then placed in a pressure cooker set to +250°F (+121°C). After an hour, the VHP100 is removed and measured again, showing absolutely no change in resistance (< 1 ppm measurement accuracy).
 With their demonstrated stability through high temperatures and humidity, VFR Bulk Metal Foil hermetically sealed resistors are ideal for applications requiring unquestioned long-term stability.
The pressure cooker demo is available now on the Vishay Foil Resistors website, at
