HIGH TEMPERATURE PRODUCTS

Resistors are the passive building blocks of an

electrical circuit. They may be used for dropping the

voltage, buffering the surge when the circuit is turned

on, providing feedback in a monitoring loop, sensing

current flow, etc. When the application requires stability

over time and load, initial accuracy, minimal change

with temperature for more than 175°C, resistance to

moisture and a number of other characteristics that will

be described below, only Vishay Foil Resistors have the

attributes needed for such application. Over the past

few months, there has been considerable growth in the

demand for precise, stable and reliable resistors that

can operate in harsh environments and especially at

high temperatures to 200°C. Many analog circuits for

industrial, military, aerospace, medical, down-hole, oil well

,and automotive applications require passive components

Foil shown in black, etched spaces in white

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.

LONG-TERM STABILITY

Some process controls in high temperature environment

are not very critical but many, many are—particularly

when a process is operating near a tipping point where

it could get out of control quickly if not well monitored.

Entire production batches have been lost or suffered

reduced reliability when critical parameters were not kept

within narrow limits. One thing that can cause this to

happen is changes in the resistor over time. Reference

points in the control process thus become less and

less reliable. Repeatability of the process from batch to

batch begins to drift. The process is changing while the

monitors appear to be holding it within specified limits

because the precision resistor is producing a different

output voltage than it was in previous runs for the same

sensor output. So the process appears to be under

control when, in reality, it is experiencing an undetected

drift.

Long-term stability is thus one of the considerations that

drive the selection of which resistor technology to use in

the application. As for surface-mount chip resistors, the

leaded option is much better due to reduced stress on the

resistor from the PCB.

Vishay Foil Resistors

THERMAL EMF

In a resistor, the resistance is composed of a resistance

element of one material and two terminations of a

different material. When the junction of the element and

the termination is heated in a closed circuit, there is a DC

voltage generated in the circuit (see Seebeck and Peltier

Effects). If both termination junctions of the resistor are

at exactly the same temperature, there is no net thermal

EMF voltage generated in the circuit due to thermal

EMF error voltages in the resistor. In fact, however, the

terminals are very seldom at the same temperature

because their temperatures are influenced by uneven

power dissipation within the resistor, differential heating

from other components on the board, and heat conducted

along the board itself. Obviously, in a sense resistor that’s

supposed to accurately convert a current to a voltage,

the presence of an extraneous thermal EMF voltage could

constitute a significant error source in the system. That

is why it’s important that Bulk Metal

Foil resistors have

a thermal EMF voltage of less than 0.1 μV/°C difference

across the element to termination junction.

in the presence of the electric field established across

the element by the DC voltage. This etchant then begins

to remove resistance material from the resistance grid,

transports it across the surface of the element and

deposits it on another portion of the resistance grid. This

process can open a thin film resistor in just a few hours of

operation or effect a more gradual increase in resistance

over a longer period of time, opening after months rather

than hours. The resistance grid of the Bulk Metal Foil

resistor is hundreds of times thicker than an equivalent

value thin film resistor so it would take hundreds of times

more chemistry to do the same amount of damage as to

the metal and thin film resistors.

TEMPERATURE COEFFICIENT OF

RESISTANCE (TCR)

TCR is more important in some applications than in

others. Where the sense resistor is in an office control

station environment the temperature is fairly well

controlled over a narrow range but when the sense

resistor is close to the processes the sense resistor may

be exposed to a much higher range of temperatures.

Using a thin film resistor at ±10 ppm/°C would result in

a 100 ppm (0.01%) error if the ambient changes by only

10°C. If the temperature of operation is not close to the

midpoint of the temperature range used to quantify the

TCR at ±10 ppm/°C, it would result in a much larger

error over higher temperature ranges. A Bulk Metal Foil

resistor would only change 0.0002% to 0.002% over that

same 10°C span, depending upon which model is used

(0.2 ppm/°C to 2 ppm/°C.) And for larger temperature

spans, it would be even more important to use the Bulk

Metal Foil resistor for its inherently low TCR.

RELIABILITY

In addition to possible ESD damage, there are other

reliability considerations. there is another, often

overlooked reliability concern: moisture. All epoxy

coatings and plastic encapsulants are hygroscopic;

they absorb moisture from the air. Under the varying

temperature, pressure, and humidity conditions of normal

operations, moisture is drawn through the external

coatings and elevates the humidity level of the inside

of the resistor to a higher level than the unrestrained

fluctuating conditions outside the resistor itself. If the

resistor were to run at high power and generate a lot of

heat, the moisture would be driven out of the resistor

and there would be no humidity consequences. But the

best conditions for long term load-life stability are the

worst conditions for moisture damage in low DC power

applications. When the moisture is drawn into the resistor

it imports minute ions from the coating to the resistor

element’s surface where it adds to any residuals left

during production. These materials form a mild etchant

HARMONIC DISTORTION

Harmonic distortion is an important consideration in the

choice of precision resistors for sensitive applications. A

significant signal voltage across the resistor may change

the resistance value depending on the construction,

material, and size. Under these conditions Bulk Metal Foil

resistors behave more linearly than other resistor types.
