VPR220Z (Z-Foil) Vishay Foil Resistors Ultra High Precision Z-Foil Power Resistor in TO-220 Configuration with TCR of ± 0.05 ppm/°C, Tolerance to ± 0.01 % and Power Rating to 8 W FEATURES • Temperature coefficient of resistance (TCR): ± 0.05 ppm/°C typical (0 °C to + 60 °C) ± 0.2 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.) • Tolerance: to ± 0.01 % • Power coefficient of resistance (PCR) “ΔR due to self heating”: 4 ppm/W typical • Electrostatic discharge (ESD) above 25 000 V Vishay Foil Resistors manufacture any resistance value within the given resistance range (e.g. 10 Ω or 10.1234 Ω) without influencing cost or lead time • Load life stability: ± 0.005 % (25 °C, 2000 h at rated power) • Resistance range: 5 Ω to 10 kΩ (Any value available within resistance range e.g. 1K2345) • Power rating: 8 W chassis mounted (per MIL-PRF-39009) Model VPR220Z, made from Vishay Bulk Metal® Z-foil, offers very low TCR, high stability, tight tolerance, low PCR and fast response time in a small molded resistor. The Z-foil technology provides a significant reduction of the resistive components sensitivity to ambient temperature variations and applied power changes. Designers now can guarantee a high degree of stability and accuracy in fixed resistor applications using solutions based on Vishay’s revolutionary Z-foil technology.
