VSMP2ꢀ18 (Z-Foil)

Vishay Foil Resistors

Ultra High Precision Foil Wraparound Surface Mount Chip Resistor

with Temperature Coefficient of Resistance (TCR) of ꢀ0ꢀꢁ ppmꢂ/C,

and Load Life Stability of ꢀ0ꢀꢀꢁ ꢃ (ꢁꢀ ppm)

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.)

 Resistance range: 10 to 20 k(higher values

from 20 k to 150 k can be supplied on request)

 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)

INTRODUCTION

Vishay VSMP2018 ultra high precision Bulk Metal^®Z-Foil

resistor is the result of a new concept in resistors

manufacturing: A proprietary Bulk Metal Foil of known and

controllable properties is applied to a special ceramic

substrate. A resistive pattern is then photoetched by an

ultra-fine technique developed by Vishay.



Tolerance: to 0.01 %

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

5 ppm at rated power

 Power rating: to 750 mW at + 70 °C

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

power

 Electrostatic discharge (ESD) up to 25 000 V

 Short time overload:  0.005 %

 Non-inductive, non-capacitive design

This process results in a resistor element that combines the

all important characteristics of low temperature coefficient

(TCR), long-term stability, ESD immunity, tight tolerance,

non-inductance, low capacitance and low noise.

These characteristics are optimum, approaching in total

performance the theoretical ideal, a straight wire.



Rise time: 1 ns effectively no ringing

 Current noise: - 40 dB

 Voltage coefficient < 0.1 ppm/V

 Non inductive: < 0.08 µH

 Non hot spot design

The behavior of Vishay resistors under load is characterized

by a very small initial resistance change which occurs within

the first 500 h of the test. Only insignificant resistance

changes are observed upon continuation of the test, and no

signs of wear out appear even at full load over several

thousands hours.

 Terminal finish: lead (Pb)-free, tin/lead alloy

 Compliant to RoHS directive 2002/95/EC

 Matched sets are available on request

 Prototype quantities available in just 5 working days or

sooner, please contact foil@vishaypg.com

 For better performances please contact us

The VSMP has a full wraparound termination which ensures

safe handling during the manufacturing process, as well as

providing stability during multiple thermal cyclings.

APPLICATIONS

Our application engineering department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please

 Automatic test equipment (ATE)

 High precision instrumentation

 Laboratory, industrial and medical

 Audio

 EB applications (electron beam scanning and recording

equipment, electron microscopes)

 Down hole instrumentation

 Communication
