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.
• Non Inductive: < 0.08 µH
• Non Hot Spot Design
• Terminals: silver coated copper alloy
