wilbrecht ledco, inc' NI-Chrome alloy foil resistors are constructed to reliably meet the tightest temperature coefficients and resistance tolerances while providing long term stability in high reliability applications.

We offer a TCR of ± 2.5 ppm/°C over the range - 55°C to +125°C and resistance tolerances to 0.005%. Our resistors have less than a 0.2% resistance change over 10,000 hours at rated temperatures and power.

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.
