INTRODUCTION

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.

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.

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.

These specifications are based on tests performed in

accordance with methods prescribed by appropriate

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

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.

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.

Our application engineering department is available to

advise and make recommendations.
