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). IM PR O VE D 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 contact us.
