CSM3637P

Vishay Foil Resistors

Ultra High Precision, Surface Mount Metal Strip Resistor with

Increased Power to 5W (40A max), Resistance Values from 3 m,

and TCR to ± 15 ppm/°C

FEATURES

 Resistance range: 3 m to 100 m

NEW

 Temperature coefficient of resistance (TCR):

15 ppm/°C maximum

(- 55 °C to + 125 °C, + 25 °C ref.)

INTRODUCTION

 Load life stability: ± 0.2 % (70 °C, 2000 h at rated

power)

The CSM3637P is a low value current sense resistor,

providing power and precision in a four terminal, surface

mount configuration. Its all welded construction is made up

of a Bulk Metal^®resistive element with plated copper

terminations.

 Power rating: to 5 W (see Table 1)

 Resistance tolerance: to ± 0.1 %

 Vishay Foil resistors are not restricted to standard values;

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

cost or delivery (e.g. 10.2345 m vs. 10 m)

There are many current sense resistors on the market. Until

now the combination of very stable and precise resistors

with low TCR of ± 15 ppm/°C maximum, tight tolerance of

± 0.1 % and load life stability of ± 0.2 % (2000 h, + 70 °C at

rated power) was not easily available.

 Short time overload: ± 0.1 % typical

 Proprietary processing technique produces extremely low

resistance values with improved stability

The key performance of the new CSM3637P is its high rated

power up to 5W. This option became available due to a

special design which consists of a heat sink on the top of the

resistive element, thus allowing a better heat dissipation.

 All welded construction

 Solderable terminations

 Very low inductance 0.5 nH

 Excellent frequency response to 50 MHz

These specifications are based on tests performed in

accordance with methods prescribed by appropriate

MIL-PRF standards (MIL-PRF-55342 and MIL-PRF-49465).

 Low thermal EMF < 3 µV/°C (DC offset error, significant for

low values)

The four terminal device separates the current leads from

the voltage sensing leads. This configuration eliminates the

effect of the lead wire resistance from points A to B and

C to D.

 Maximum current: up to 40 A

 Four terminal (Kelvin) design: allows for precise and

accurate measurements

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

In addition, a key feature of the CSM3637P is its low thermal

EMF design (very important for low ohmic value DC

applications). The welded terminals make intimate contact

with the chip thereby minimizing temperature differentials.

 Prototype quantities available in just 5 working days

or sooner. For more information, please contact
