VPR220, VPR221 Vishay Foil Resistors Bulk Metal(R) Foil Technology Precision Foil Power Resistors in TO-220 Configuration FEATURES * Power: 8 watts chassis mounted (per MIL-R-39009) * Load Life Stability: 0.05% maximum R at rated power and temperature for 2,000 hours THROUGH HOLE Product may not be to scale 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. * Temperature Coefficient of Resistance: to 5ppm/C * Resistance Range: 0.5 to 10K * Tolerance: To 0.01% * Low Thermal EMF: 0.15V/C maximum (lead effect) * Non-Inductive Construction * Heat sink is isolated TABLE 1 - SPECIFICATIONS Load Life Stability at 2,000 hrs 0.05% max R under full rated power @ + 25C Shelf Life Stability 0.0025% R/yr Power Rating @ + 25C 8 watts or 3 amps2 on heat sink3 1.5 watts or 3 amps2 in free air Further derating not necesary.
