VPR220S, VPR22ꢂS

Vishay Foil Resistors

Bulk Metal^®Foil Technology Precision Foil Power Surface Mount

Resistors in TO-220 Configuration with TCR of 2 ꢀꢀpm/C,

Tolerance of to 0ꢁ0ꢂ ꢃ and Power Rating to 8 W

FEATURES

•

Temperature coefficient of resistance (TCR):

2 ppm/°C typical (- 55 °C to + 125 °C,

+ 25 °C Ref.)

• Tolerance: to 0.01 % (see tables 1 and 2)

• Electrostatic discharge (ESD): above 25 000 V

• Load life stability: 0.005 % (25 °C, 2000 h at rated power)

• Resistance range: 0.5 Ω to 10 kΩ

• 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 µH

• Non hot spot design

Any value at any tolerance within resistance range

Models VPR220S AND VPR221S, made from Vishay Bulk

Metal^®foil, offer low TCR, high stability, tight tolerance and

fast 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.

• Thermal EMF: 0.05 µV/°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 h. For more

information, please contact foil@vishaypg.com
