• Electrostatic discharge (ESD) up to 25 000 V

• Resistance range: 10 Ω to 125 kΩ (for lower and higher

values, please contact us)

• Vishay Foil resistors are not restricted to standard values;

specific “as required” values can be supplied at no extra

cost or delivery (e.g. 1K2345 vs. 1K)

• Non-inductive, non-capacitive design

• Short time overload ≤ 0.005 % (50 ppm)

• Non hot spot design

• Rise time: 1 ns effectively no ringing

• Current noise: - 40 dB

INTRODUCTION

One of the most important parameters influencing stability is

the temperature coefficient of resistance (TCR). Although the

TCR of Bulk Metal^®Foil resistors is considered extremely

low, this characteristic has been further refined over the

years.

The VFCP Series utilizes ultra precision Bulk Metal^®Z-Foil.

The Z-Foil technology provides a significant reduction to the

resistive element’s sensitivity to ambient temperature

variations (TCR) and to self heating when power is applied

(power coefficient).

• Voltage coefficient < 0.1 ppm/V

• Non-inductive: < 0.08 µH

• Terminal finishes available: lead (Pb)-free, tin/lead alloy

• Compliant to RoHS directive 2002/95/EC

• Matched sets are available per request

• Prototype quantities available in just 5 working days

or sooner. For more information, please contact

foil@vishay.com

Along with the inherently low PCR and TCR, Z-Foil

technology also provides remarkably improved load life

stablility, low noise and availability of tight tolerance.

The flip chip configuration provides a substantial PCB space

saving of more than 35 % vs. a surface mount chip with

wraparound terminations. The VFCP is available in any

value within the specified resistance range.
