INTRODUCTION

Why tight tolerance is important?

Why do users employ tight tolerance resistors? A system or

a device or one particular circuit element must perform for a

specified period of time and at the end of that service period

it must still be performing within specifications.

During its useful life it may have been subjected to some

hostile service conditions and it is no longer within purchased

tolerance.

What is ratio?

The ratio tolerances available in a divider are variable and

dependent on resistor technology. Bulk Metal

foil provides

the tightest ratio tolerance available.

The tight resolution capability and overall stability of foil

resistors permit adjustment within the divider to ratio not

available with other technologies. Ratios in network form, in

a common package have a better chance of holding tight

tolerances than those formed in a discrete matched set by

sorting.

Molded foil 300144, 300145 resistors can be provided in a

tolerance as tight as 0.005 %. Theoretically, ratios such as

these can be made initially with other resistor technologies.

However, less stable products will not hold these tight ratios

tolerances over time and applied stresses like voltage and

temperature.

Vishay Bulk Metal foil dividers/networks 300144, 300145

hold their ratio tolerances under defined circumstances.

Networks with tight ratio tolerances and controlled tracking

extend the useful life of equipment, whether expressed as

mean-time-between-failures (MTBF) or service periods to

recalibration or end-of-life-cycle.

How to avoid thermal EMF?

When the resistor’s terminals and the resistive element are

made of dissimilar metals and two junctions are at a different

temperature, a voltage is produced which is called “thermal

EMF”.

The level of voltage output is a function of the metals

involved and the differential temperature. The voltage

produced is either positive or negative depending on which

junction is considered as a reference point. Virtually all

resistive products have these metallic junctions. It is

presumed they will eventually be terminated to copper as a

final metallic combination and therefore copper is used as a

typical reference material.

300144, 300145 have the lowest thermal EMF’s because all

junctions have low microvolts outputs. Moreover,

construction of the resistive element is such that the input

and output junctions of the resistor are so close that the

temperature gradients between then is highly unlikely. These

design factors produce a divider with very low thermal EMF.

Our application engineering department is available to

advise and make recommendations. For non-standard

technical requirements and special applications. Please
