FEATURES

•

Temperature Coefficient of Resistance (TCR):

0.0ꢀ ppm/°C typical (0 °C to + 60 °C)

0.2 ppm/°C typical (- ꢀꢀ °C to + 12ꢀ °C,

- 2ꢀ °C Ref.)

Pb-free

COMPLIANT

• Tolerance: to 0.01 ꢁ

• Power Coefficient of Resistance (PCR) “ΔR

due to self heating”: ꢀ ppm at rated power

Any value at any tolerance available within resistance range

• Electrostatic Discharge (ESD) above 2ꢀ 000 V

Model VPR220SZ, made from Vishay Bulk Metal^®Z-Foil,

offers very low TCR, high stability, tight tolerance, low PCR

and fast response time in a small surface mount molded

resistor.

• Load Life Stability: 0.00ꢀ ꢁ (2ꢀ °C, 2000 hours at Rated

Power)

• Resistance Range: ꢀ Ω to 10 kΩ

• Power Rating: 8 W chassis mounted (per MIL-PRF-39009)

• Non Inductive, Non Capacitive Design

• Current Noise: < - 40 dB

• Voltage Coefficient: < 0.1 ppm/W

• Non Inductive: < 0.08 µH

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.

• Non Hot Spot Design

• Thermal EMF: 0.0ꢀ µV/°C typical

Our Application Engineering Department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
