Metal Foil Resistors



Wilbrecht LEDCO, inc' metal foil resistors are constructed to reliably meet the tightest temperature coefficients and resistance tolerances while providing long term stability in high reliability applications.

SMD Resistors based on Vishay Precision Group (VPG) supplied materials.

Trimmed and tested to the exact value in our Huron, SD factory, a VPG authorized Precision Center.

The resistor's unique two-wire lead construction abates mechanical stresses and provides increased protection against vibration in military and aerospace applications. All production is documented to QPL standards.
