| VPR220, VPR221 Vishay Foil Resistors Bulk Metal(R) 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): Pb-free 2 ppm/C typical (- 55 C to + 125 C, Available + 25 C Ref.) RoHS* * Tolerance: to 0.01 % (see tables 1 and 2) COMPLIANT * Electrostatic Discharge (ESD): above 25 000 V * Load Life Stability: 0.005 % (25 C, 2000 hours at Rated Power) * Resistance Range: 0.5 to 10 k * Power Rating: 8 W chassis mounted (per MIL-PRF-39009) * Non Inductive, Non Capacitive Design * Rise Time: 1 ns without ringing * Current Noise: < - 40 dB * Voltage Coefficient: < 0.1 ppm/V * Non Inductive: < 0.08 H * Non Hot Spot design * Thermal EMF: 0.05 V/C typical * Terminal Finishes Available: Lead (Pb)-free Tin/Lead Alloy * Any value available within resistance range (e.g. 1K234) * Prototype samples available from 48 hours. For more information, please contact foil@vishay.com * For better performances, please see VPR220Z and VPR221Z datasheets Any value at any tolerance within resistance range Models VPR220 AND VPR221, made from Vishay Bulk Metal(R) Foil, offer low TCR, high stability, tight tolerance and fast response time in a small, molded resistor. Model VPR220 is a 2 lead device. Model VPR221 is a 4 lead Kelvin connected device. The 4 leaded version is highly recommended for precision applications requiring ohmic values of 100R or less.
