VSA101 (Z-Foil)

Vishay Foil Resistors

Ultra High Precision Axial Z-Foil Resistor with

TCR of 0ꢀ0ꢁ ꢂꢂpm/C, PCR of ꢁ ꢂꢂp at Rated Power,

Tolerance of 0ꢀ00ꢁ ꢃ and Load Life Stability of 0ꢀ00ꢁ ꢃ

FEATURES

INDUSTRY BREAKTHROUGH

• 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.)

• Power coefficient of resistance “ΔR due to

self heating”: 5 ppm at rated power

• Rated power: 0.6 W at 70 °C; 0.3 W at 125 °C

• Resistance tolerance: to 0.005 %

• Load life stability: to 0.005 % at 70 °C, 2000 h at rated

power

• Resistance range: 5 Ω to 100 kΩ

• Vishay Foil resistors are not restricted to standard values,

we can supply specific “as required” values at no extra cost

or delivery (e.g. 100.1234 Ω vs. 100 Ω)

• Electrostatic discharge (ESD) up to 25 000 V

• Non inductive, non capacitive design

• Rise time: 1.0 ns effectively no ringing

• Current noise: ≤ - 40 dB

INTRODUCTION

The VSA101 Axial Bulk Metal^®Z-foil resistor is Vishay’s

answer to the industry’s demand for ultra-high precision

resistors with axial terminations.

The Z-foil technology provides a significant reduction of the

resistive component’s sensitivity to ambient temperature

variations (TCR) and applied power changes (PCR). This,

along with all the additional Z-foil benefits presented in the

features section, allows designers to guarantee the highest

degree of stability and accuracy in fixed-resistor applications

using solutions based on Vishay’s revolutionary Z-foil

technology.

• Thermal EMF: 0.1 µV/°C maximum; 0.05 µV/°C typical

• Voltage coefficient: < 0.1 ppm/V

• Non inductive: 0.08 µH

• Terminal finishes available: lead (Pb)-free

tin/lead alloy

• Maximum working voltage: 300 V

• Matched sets are available per request

• For better performances please contact us

• Testing available per EEE-INST002

Our application engineering department is available to

advise and to make recommendations. For non-standard

technical requirements and special applications, please

APPLICATIONS

• Precision amplifiers, high precision instrumentation,

medical and automatic test equipment

• Laboratory, audio (high end stereo equipment)

• EB applications, military, airborne and space

• Down-hole (high temperature)
