VPG Announces 'Selecting Precision Resistors' Educational Road Show for India in October

Available by Customer Request, Educational Session Illustrates Differences in Thin Film, Thick Film, and Foil Resistors

MALVERN, PA--(Marketwire - Oct 3, 2011) - Vishay Precision Group, Inc. (NYSE: VPG) today announced that its Vishay Foil Resistors division (VFR) will be presenting a technical program during an educational road show in October for design engineers in India. Available by customer request and held at their own sites, the "Selecting Precision Resistors" educational program is designed to assist designers in resistor selection by clarifying the differences among various precision resistor technologies beyond the simple assertions of their publicized datasheets.

Whether an application requires the best available combination of all important resistor characteristics, or just one or two of the best available specific characteristics, exact knowledge of all resistor technologies is essential when selecting a device. Resistors built on different technologies may seem alike on the surface, and may even have similar specifications; however, the differences among them remain quite significant. Inherent in each type of resistive material are certain design and processing variations that strongly influence device electrical performance in ways that may become apparent only after a period of use in the end product.

In "Selecting Precision Resistors," VFR covers the electrical properties and stress factors of thick film, thin film, and foil resistors, emphasizing the theoretical and actual resistor performance characteristics of Bulk Metal® Foil resistors, including: temperature coefficient of resistance (TCR), power TCR (PCR), ESD, short-time overload, thermal EMF, and stability.

The program includes a demonstration that illustrates in real-time the differences among the three resistor technologies when exposed to several stress factors. Stress analysis principles are discussed, in addition to methods for locating and predicting stress concentrations in analog circuits using common techniques.

In the road show, VFR application engineers will present relevant testing protocols developed by military and space customers that may be used as a basis for testing components, including the EEE-INST-002 guidelines. Developed by NASA, the EEE-INST-002 guidelines are flexible enough to accept any technology and part type, and VFR presently supplies five products under these specifications for critical projects.

Cities on VPG's road show include Bangalore, Hyderabad, Ahmadabad, and Mumbai. Information about scheduling a technical session is available at
