They resign themselves to making constant adjustments

and troubleshooting. But in fact these can be avoided.

Instability is often traceable to a few supposedly “fixed”

resistors which are not really fixed at all. If these resistors

would only retain their original values, there would be

no need for costly controls and other compensating

circuitry. That’s why the only resistor for applications

such as these is Z Bulk Metal

Foil. In high-end audio

equipment, careful selection of resistors is one of the

best ways to avoid or minimize noise and distortion in the

signal path. Noise is an unwanted wide spectrum signal

that may be superimposed on any useful signal, including

DC. Resistors, like other passive components, are noise

sources to various degrees, depending upon resistance

value, temperature, applied voltage, and resistor type.

Many experiments have been done to show why some

resistors are “noisier” than others. But the only test

that audio experts and audiophiles have agreed on is

comparing the level of fidelity that results when different

resistor technologies are used in actual audio systems.

High-end analog audio applications require low intrinsic

noise, high linearity of amplification, and minimal dynamic

distortion. The typical audio amplifier consists of a voltage

preamplifier (preamp) and power amplifier (final driver).

The voltage preamplifier deals with low-level signals.

That is why its intrinsic noise level is critical. Resistors are

among the principal noise sources in the amplifiers. The

main requirements for the audio power amplifier are high

linearity of amplification and minimal dynamic distortion.

Vishay Foil resistors are characterized by very low intrinsic

non-linearity of the resistive element, which is made from

cold-rolled bulk metal.

The AUR, composed of VFR’s Bulk Metal

Z-foil

technology, with improved sound quality, provides

a combination of low noise and low inductance/

capacitance, making it unrivalled for applications requiring

low noise and distortion-free properties.

INTRODUCTION

Many manufacturers and users of precision electronic

equipment suffer needlessly from unexplained instabilities

and drifts due to noise effects and harmonic distortion.

Note

To acquire a precision resistance value,

the Bulk Metal

Foil chip is trimmed by

selectively removing built-in “shorting bars.”

To increase the resistance in known increments,

marked areas are cut, producing progressively

smaller increases in resistance. This method

reduces the effect of “hot spots” and improves

the long-term stability of the Vishay Foil resistors.

POST MANUFACTURING OPERATIONS

(PMO)

Many audio analog applications can include requirements

for performance under conditions of stress beyond the

normal and over extended periods of time. This calls for

more than just selecting a standard device and applying

it to a circuit. The standard device may turn out to be all

that is needed but an analysis of the projected service

conditions should be made and it may well dictate a

routine of stabilization known as post manufacturing

operations or PMO. The PMO operations that will be

discussed are only applicable to Bulk Metal Foil resistors.

They stabilize Bulk Metal Foil resistors while they are

harmful to other types. Short time overload, accelerated

load life, and temperature cycling are the three PMO

exercises that do the most to remove the anomalies down

the road. VFR Bulk Metal Foil resistors are inherently

stable as manufactured. These PMO exercises are only

of value on Bulk Metal Foil resistors and they improve the

performance by small but significant amounts. Users are

encouraged to contact Vishay Foil Resistors’ applications

engineering for assistance in choosing the PMO

operations that are right for their application.

be reduced by reducing resistance, temperature, or signal

bandwidth.

Shot or fluctuation noise is caused by the discrete nature

of charge carriers and fluctuation of their number in the

unit of volume. Shot noise can be reduced by reducing

bandwidth or increasing current. The spectral density

of voltage in both thermal and shot noises is uniformly

distributed in entire range of frequencies (“white” noise).

The level of these types of noise does not depend on

resistor type (resistive element material).

Current (excess, flicker) noise has 1/f type spectral

density of voltage (“pink” noise). Its level essentially

depends on resistor material. Current noise can be

reduced by (a) avoiding use of the low frequency band,

(b) reducing current, (c) increasing the volume of resistive

material, i.e. by using resistors with higher rated power

than is needed for proper power dissipation, or (d) using

less noisy resistive materials.

Carbon composition resistors are the noisiest such device

type followed by Thick Film and Thin Film resistors. The

least noisy are bulk metals and metal alloys (foil, wire). At

that, negligible capacitance/inductance of foil resistors

(when compared to wirewound resistors) significantly

reduces probability of self-excitation or “ringing” of

amplification circuit.This is why Bulk Metal

foil resistors

are such a good choice for low-noise applications.

SEVERAL TYPES OF NOISE

FOUND IN RESISTORS

Thermal noise is caused by thermal movement of

electrons in resistive material and gets worse as

resistance and temperature increase. Thermal noise can
