Z201 Vishay Foil Resistors Ultra-Performance Aerospace and Instrumentation Resistor FEATURES • Industry Breakthrough • Nominal TCR: 0.2ppm/°C MIL range* • Load Life Stability: 0.005% 2000 Hrs @ 0.1Watt • Absolute Tolerance: To 0.005% Product may not be to scale • Resistance Range: 100Ω to 100KΩ • Power Rating: 0.6Watts @ 70°C (0.3 Watts @ 125°C) THROUGH HOLE • Current Noise: 0.010µV/V (RMS) • Thermal EMF: 0.1µV/°C Max; 0.05 Typical The Z201 (0.150 lead spacing) and Z201L (0.200 lead spacing) Bulk Metal® Foil resistors represent an industry breakthrough. This is the 3rd in a series of ultra-precision resistors since the first Bulk Metal® Foil resistor was introduced by Vishay in 1962. Each represents an improvement on the earlier model. The TCR slope of the Z201 is 0.2ppm/°C (MIL range) and is an order of magnitude better than the original S102C. The Bulk Metal® Foil resistor is the ultimate choice in the most demanding analog applications.

It does not vary from lot to lot nor by ohmic value.
