Vishay Foil Resistors

High Precision Bulk Metal^®Foil Surface Mount Voltage Divider,

TCR Tracking of < 0.5 ppm/°C, Tolerance Match of 0.01 %

and Stability of 0.005 % (50 ppm)

FEATURES

• Temperature Coefficient of Resistance (TCR):

Pb-free

Absolute: 2 ppm/°C typical

(- 55 °C to + 125 °C, + 25 °C Ref.)

Available

RoHS*

Tracking: 0.5 ppm/°C typical

COMPLIANT

• Tolerance: Absolute: 0.02 %; Match: 0.01 %

Any value at any ratio available within resistance range

• Power Rating at 70 °C: Entire Package: 0.1 W

Each Resistor: 0.05 W

INTRODUCTION

• Ratio Stability: 0.005 % (0.05 W at 70 °C, 2000 hours)

• Resistance Range: 100 Ω to 20 kΩ per resistor

• Large Variety of Resistance Ratios: 1:200

• Electrostatic Discharge (ESD) above 25 000 Volts

• Short Time Overload ≤ 0.005 %

Bulk Metal^®Foil Technology out-performs all other resistor

technologies available today for applications that require High

Precision and High Stability.

This technology has been invented, patented and pioneered

by Vishay. Products based on this technology are the most

suitable for a wide range of appilcations.

• Non Inductive, Non Capacitive Design

• Rise Time: 1.0 ns without ringing

BMF technology allows to produce customer oriented

products designed to satisfy challenging and specific

technical requirements. Model DSM offers Low TCR (both

absolute and tracking), Excellent Load Life Stability, Tight

tolerance, Excellent Ratio Stability, and Low Current Noise,

all in one package.

• Current Noise: < - 40 dB

• Voltage Coefficient: < 0.1 ppm/V

• Non Inductive: < 0.08 µH

• Non Hot Spot Design

• Terminals: silver coated copper alloy

• Any value available within resistance range (e.g. 1K2345)

The DSM surface mount divider provides a matched pair of

Bulk Metal^®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.

• Prototype samples available from 48 hours. For more

information, please contact foil@vishay.com

• For better performances, please see DSMZ datasheet

Our Application Engineering Department is available to

advise and make recommendations. For non-standard

technical requirements and special applications, please
