INTRODUCTION

Bulk Metal^®Foil (BMF) Technology outperforms all other

resistor technologies available today for applications that

require High Precision and High Stability.

This technology has been pioneered and developed by

Vishay, and products based on this technology are the most

suitable for a wide range of applications.

• Non Hot Spot Design

• Terminal Finishes available: Lead (Pb)-free

Tin/Lead Alloy

BMF technology allows us to produce Customer Orientated

products designed to satisfy challenging and specific

technical requirements.

• For better performances please contact us

• Available with Z-Foil technology, please see SMNZ

datasheet

Model SMN offers low TCR (absolute and tracking),

excellent load life stability, tight tolerance (absolute and

match), excellent ratio stability, low thermal EMF, low current

noise and low voltage coefficient - all in the same resistor.

APPLICATIONS

• Instrumentation Amplifiers

• Bridge Networks

• Differential Amplifiers

• Ratio Arms in Bridge Circuits

• Medical and Test Equipment

• Military

Vout

The SMN Surface Mount Network is made up of 4

independent BMF resistors in a small standard molded

epoxy package with 50 MIL lead pitch (JEDEC MS-012

package).

SMN

• Airborne etc.

The electrical specification of this integrated construction

offers improved performance and better real estate utilization

over discrete resistors and matched sets. The resistor may

be used independently or as divider pairs.
