INTRODUCTION

Bulk Metal

Z-Foil technology out-performs all other resistor

technologies available today for applications that require

ultra-high precision and ultra-high stabilitly.

The Z-Foil technology provides a significant reduction of the

resistive element’s sensitivity to ambient temperature

variations (TCR) and to self heating when power is applied

(power coefficient).

The DSMZ offers low TCR (both absolute and tracking), low

PCR, excellent load life stability, tight tolerance match,

excellent ratio stability, low thermal EMF, and low current

noise - all in one package.

The

DSMZ

surface mount divider provides a matched pair of

Bulk Metal

Z-Foil resistors in a small epoxy molded

package. The electrical specification of this integrated

construction offers improved performance and better real

estate utilization over discrete resistors and matched pairs.

Our application engineering department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
