VPR220, VPR221 Vishay Foil Resistors Bulk Metal Foil Technology Precision Foil Power Resistors in TO-220 Configuration with TCR of 2 ppm/C, Tolerance of to 0.01 % and Power Rating to 8 W FEATURES Temperature coefficient of resistance (TCR): 2 ppm/C typical (- 55 C to + 125 C, + 25 C ref.) Tolerance: to 0.01 % (see tables 1 and 2) Electrostatic discharge (ESD): above 25 000 V Load life stability: 0.005 % (25 C, 2000 h at rated power) Any value at any tolerance within resistance range Resistance range: 0.5 to 10 k Power rating: 8 W chassis mounted (per MIL-PRF-39009) Models VPR220 AND VPR221, made from Vishay Bulk Non-inductive, non-capacitive design Metal Foil, offer low TCR, high stability, tight tolerance and Rise time: 1 ns without ringing fast response time in a small, molded resistor. Model Current noise: < - 40 dB VPR220 is a 2 lead device. Model VPR221 is a 4 lead Kelvin Voltage coefficient: < 0.1 ppm/V connected device. The 4 leaded version is highly Non inductive: < 0.08 H recommended for precision applications requiring ohmic Non hot spot design values of 100R or less. Thermal EMF: 0.05 V/C typical Terminal finishes available: lead (Pb)-free or tin/lead alloy Any value available within resistance range (e.g. 1K234) TABLE 1 - VPR220 Prototype samples available from 48 h.
