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

NOTES:

TABLE 1 - SPECIFICATIONS

1. Maximum is 1.0% A.Q.L. standard for all

specifications except TCR. Typical is a designers

reference which represents that 85% of the units

supplied, over a long period of time, will be at least the

figure shown or better.
