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.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications, please
