Vishay Foil Resistors

Bulk Metal^®Foil Technology Industrial Precision Resistors

with TCR of ꢀ ꢁꢁpm/C and Tolerance of ꢂ0ꢂꢃ ꢄ

FEATURES

• Temperature coefficient of resistance (TCR) ⁽¹⁾

4 ppm/°C (0 °C to + 60 °C)

8 ppm/°C (- 55 °C to + 125 °C, + 25 °C ref.)

• Resistance range: 0.5 Ω to 1 MΩ (higher or lower

values of resistance are available)

• Vishay Foil resistors are not restricted to standard values,

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

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

• Tolerance: to 0.01 % (100 ppm)

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

power

INTRODUCTION

Bulk Metal^®Foil technology out performs all other resistor

technologies available today for applications that require

high precision and high stability.

• Electrostatic discharge up to 25 000 V

• Non inductive, non capacitive design

• Rise time: 1 ns effectively no ringing

• Current noise: - 40 dB

• Thermal EMF: 0.05 µV/°C typical

• Voltage coefficient: < 0.1 ppm/V

• Inductance: 0.08 µH

This technology has been pioneered and developed by

VISHAY, and products based on this technology are the

most suitable for a wide range of applications.

Generally Bulk Metal Foil technology allows us to produce

customer orientated products designed to satisfy challenging

and specific technical requirements.

• Matched sets available

• Terminal finish: lead (Pb)-free

The VSR series of resistors is a low cost version of the well

established S series of resistors. These resistors are made

of foil elements so all of the inherent performance of foil is

retained. They do not however, have the same TCR or

tolerance ranges (see table 1 for details). These products

find a wide range of usage in high end stereo equipment and

some grades of test and measurement equipment.

tin/lead alloy

• Prototype samples available from 72 h. For more

information, please contact foil@vishay.com

• For better performances please review the S Series

datasheet

Note

Standoffs are dimensioned to provide a minimum lead

clearance of 0.010" between the resistor body and the

printed circuit board, when the standoffs are seated on the

board. This allows for proper cleaning after the soldering

process.
