DSMZ (Z-Foil)

Vishay Foil Resistors

Ultra High Precision Bulk Metal^®Z-Foil Surface Mount Voltage

Divider, TCR Tracking of < 0.1 ppm/°C, PCR of ꢀ ppm

at Rated Power and Stability of 0.00ꢀ ꢁ (ꢀ0 ppm)

FEATURES

 Temperature coefficient of resistance (TCR):

Absolute: 0.05 ppm/°C typ. (0 °C to + 60 °C)

0.2 ppm/°C typ. (- 55 °C to + 125 °C, + 25 °C Ref.)

Tracking: 0.1 ppm/°C typical

 Power coefficient tracking

“R due to self heating”: 5 ppm at rated power

INTRODUCTION

Bulk Metal^®Z-Foil technology out-performs all other resistor

 Power rating at 70 °C: entire package: 0.1 W,

each resistor: 0.05 W

technologies available today for applications that require

ultra-high precision and ultra-high stabilitly.

 Tolerance: absolute: 0.02 %; match: 0.01 %

 Ratio stability: 0.005 % (0.05 W at 70 °C, 2000 h)

 Resistance range: 100  to 10 k per resistor

 Large variety of resistance ratios: 1:100

 Foil resistors are not restricted to standard values/ ratios;

specific “as required” values/ratios can be supplied at no

extra cost or delivery (e.g. 1K234/2K345 vs. 1K/2K)

 Electrostatic discharge (ESD) up to 25 000 V

 Short time overload  0.005 %

 Non-inductive, non-capacitive design

 Rise time: 1 ns effectively no ringing

 Current noise: < - 40 dB

 Thermal EMF: 0.05 µV/°C typical

 Voltage Coefficient: < 0.1 ppm/V

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

 Compliant to RoHS directive 2002/95/EC

 Prototype quantities available in just 5 working days

or sooner. For more information, please contact

foil@vishaypg.com

Our application engineering department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
