VFD244Z (Z-Foil)

Vishay Foil Resistors

Bulk Metal^®Foil Technology Ultra High Precision Z-Foil Voltage Divider

Resistors with TCR Tracking to 0.1 ppm/°C, Power Coefficient Tracking

of 5 ppm at Rated Power, and Tolerance Match to 0.005 % (50 ppm)

FEATURES

 Temperature coefficient of resistance (TCR):

absolute: ± 0.05 ppm/°C typical (0 °C to + 60 °C)

± 0.2 ppm/°C typical (- 55 °C to + 125 °C,

+ 25 °C ref.)

TCR tracking: 0.1 ppm/°C typical

 Tolerance: absolute and matching to 0.005 % (50 ppm)

 Resistance range: 1  to 100 k per resistive element

 Power coefficient tracking “R due to self heating”: 5 ppm

at rated power

 Power rating: up to 1 W at 70 °C, for the entire package,

Vishay Foil resistors are not restricted to standard

values/ratios; specific “as requested” values/ratios can be

supplied at no extra cost or delivery (e.g. 1K2345 vs. 1K)

divided proportionally between the two values

 Load life ratio stability: < 0.005 % (50 ppm) 1 W at 70 °C

for 2000 h

 Maximum working voltage: 350 V

 Electrostatic discharge (ESD) up to 25 000 V

 Non-inductive, non-capacitive design

 Rise time: 1 ns effectively no ringing

 Current noise: 0.010 µV_RMS/V of applied voltage (< - 40 dB)

 Thermal EMF: 0.05 µV/°C typical

 Voltage coefficient: < 0.1 ppm/V

APPLICATIONS

 Instrumentation amplifiers

 Bridge networks

 Differential amplifiers

 Military

 Space

 Medical
