Metal-film resistor
WN series
Microprecision Electronics
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.
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.
Series WN
The WN Series is qualified to the NASA S-311-P-813 specification.
