Vishay Foil Resistors

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. BMF

technology allows us to produce customer orientated

products, designed to satisfy challenging and specific

technical requirements.

Model S series made from Vishay BMF offers low TCR,

excellent load life stability, tight tolerance, fast response

time, low current noise, low thermal EMF and low voltage

coefficient, all in one resistor.

The S series is virtually insensitive to destabillizing factors.

The resistor element is a solid alloy that displays the

desirable bulk properties of its parent material, thus it is

inherently stable and noise free.

Vishay’s Bulk Metal® S series resistors are the modern

generation of precision resistors. The standard design of

these resistors provides a unique combination of

characteristics found in no other single resistor.

Our application engineering department is available to

advise and to make recommendations. For non-standard

technical requirements and special applications, please

Notes

(1) S104F and S105F have different package dimensions (see last column). All other specifications are the same.

(2) 0.200" (5.08 mm) lead spacing available - specify S102J for S102C, and S102L for S102K.

FIGURE 2 - STANDARD IMPRINTING AND DIMENSIONS

Note

1. The standoffs shall be so located as to give a lead clearance of 0.010" minimum between the resistor body and the printed circuit board

when the standoffs are seated on the printed circuit board. This is to allow for proper cleaning of flux and other contaminants from the unit

after all soldering processes.

STANDARD OPERATIONS AND TEST

CONDITIONS

A. Standard Test Operations:

By 100 % Inspection

•Short-time overload (6.25 x rated power for 5 s)

•Resistance - tolerance check

•Visual and mechanical

By Sample Inspection

•TCR

•Environmental tests per table 3 on a quarterly basis to

establish performance by similarity

B. Standard Test Conditions:

•Lead test point: 0.5" (12.7 mm) from resistor body

•Temperature: + 23 °C ± 2 °C

•Relative humidity: per MIL-STD-202

IMPROVED PERFORMANCE TESTING (IPT)

The preceding information is based on product directly off

the production line. Improved performance (meaning

increased time stability with load and other stresses) is

available through factory conducted “Improved Performance

Testing”. The test routine is usually tailored to the users

stability objectives and product that has been screened can

be brought down to a potential load life of less than 50 ppm.

Various screen test routines are available and all anticipated

stresses must be taken into account before settling on one

specific test routine. Our applications engineering

department is prepared to discuss and recommend

appropriate routines given the full spectrum of anticipated

stresses and stability requirements.

Notes

(1) Load life ΔR maximum can be reduced by 80 %, please contact applications engineering department.

(2) Inductance (L) due mainly to the leads.

(3) The resolution limit of existing test equipment (within the measurement capability of the equipment, or “essentially zero”.)

(4) µV/°C relates to EMF due to lead temperature difference and µV/watt due to power applied to the resistor.
