Vishay Foil Resistors
Bulk Metal® Foil Technology
Precision Foil Surface Mount Power Resistors in TO-220 Configuration
FEATURES
• Leads preformed for surface mounting
• 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
Product may not
be to scale
• Temperature Coefficient of Resistance: to ± 5ppm/°C
• Resistance Range: 0.5 to 10KΩ
• Tolerance: To ± 0.01%
Models VPR220S AND VPR221S, made from Vishay Bulk
• Low Thermal EMF: 0.15µV/°C maximum (lead effect)
Metal® Foil, offer low TCR, high stability, tight tolerance and fast
• Non-Inductive Construction
response time in a small, molded resistor. Model VPR220S is
a 2 lead device. Model VPR221S is a 4 lead Kelvin connected
device. The 4 leaded version is highly recommended for
precision applications requiring ohmic values of 100R or less.
• Heat sink is isolated
• Tin/Lead (Sn 60% Pb 40%) coated termination standard.
Lead free (100% Sn) option available
