Vishay Precision Group Bulk Metal® Foil
resistors  from Texas Components

Texas Components is the largest and most experienced independent manufacturer and distributor of Bulk Metal® Foil based resistors located in the USA, having over 37 years of experience with even the most complex designs and applications. As a licensed and certified Precision Center, Texas Components is an authorized part of the Vishay Precision Group global supply chain for manufacturing and distributing resistive products made using Bulk Metal® Foil, including standard Vishay Foil Resistors as well as our own unique design applications and derivative products. Our made in the USA products are offered with no minimum order quantity, and delivery in less than one week is possible for many designs and models not otherwise in stock!

Watch this brief introduction to Bulk Metal® Foil Resistor Technology


Bulk Metal® Foil resistive products are known for their unique combination of unmatched performance in all 10 major technical areas: 

Temperature Coefficient of Resistance (TCR)
Power Coefficient of Resistance (PCR)
Voltage Coefficient of Resistance (VCR)
Thermal Electromotive Force (EMF)
Electrostatic Discharge (ESD)


Thermal Stabilization
Load Life Stability
Response Time

For any application, if your products or designs need this superior resistive performance, only Bulk Metal® Foil will meet the challenge and make possible designs and circuitry performance that are simply not possible otherwise.
