VHP100

Vishay Foil Resistors

Ultra-High Precision Hermetically Sealed Bulk Metal^®Foil Resistor

with Zero TCR, no Humidity Effect and 0.005 % Tolerance within a

Unique Construction, Minimizing the Effects of Stress Factors

FEATURES

• Essentially zero TCR

• Absolute resistance change (window):

VHP100 < 60 ppm (- 55 °C to + 125 °C)

VHP101 < 10 ppm (+ 15 °C to + 45 °C)

• Tolerance: to 0.005 % (50 ppm) - (available to

0.001 % (10 ppm))

• No humidity effect: hermetically sealed against moisture

• Load life stability: 50 ppm typical for 2000 h, 70 °C at

0.3 W

INTRODUCTION

The new VHP100 type represents a metrology breakthrough.

new construction concept combined with special

• Shelf life stability: 2 ppm typical after at least 6 years

• Resistance range: 100 Ω to 150 kΩ (higher or lower values

available on request)

treatments make this resistor the first choice in the most

demanding instrumentation and laboratory applications.

The ability of the new VHP100 to minimize the changes in

resistance value when the resistor is subjected to load

variations and thermal stresses, ensure the ultra high

performances for the tight metrology specifications.

• Vishay Foil resistors are not restricted to standard values;

specific “as required” values can be supplied at no extra

cost or delivery (e.g. 1K2345 vs. 1K)

The total error budget of 2 ppm drift and the high speed

recovery represent an improvement of almost an order of

magnitude on the earlier model.

• Electrostatic discharge (ESD) up to 25 000 V

• Non inductive, non capacitive design

• Rise time: 1 ns effectively no ringing

• Thermal stabilization < 1 s

• Current noise: 0.010 µV_RMS/V of applied voltage (< - 40 dB)

• Thermal EMF: 0.05 µV/°C typical

• Voltage coefficient: < 0.1 ppm/V

• Inductance: < 0.08 µH

• Non hot spot design

Vishay has achieved an essentially Zero Temperature

Coefficient Resistor in the VHP100 type. This oil filled

hermetically sealed device makes unique use of foil on

ceramic in such a way that self cancelling responses to

temperature are produced by combining equal and opposite

effects. This product is sold only in hermetic packages

because applications requiring this level of temperature

stability require humidity stability as well.

The value of the hermetic enclosure over the molded part is

in the long term performance. The hermetic sealing prevents

the ingress of moisture and oxygen, while the oil acts as a

thermal conductor.

• Hermeticity: 10^-7atmospheric cc/s max.

• Terminal finish: lead (Pb)-free, tin/lead alloy

• Compliant to RoHS directive 2002/95/EC

• Oil filled as standard, air filled available upon request

TCR WINDOW DEFINITION

• Load-life stability can be considerably improved through

in-house oriented tests

The TCR of the VHP100 is so small that an additional

definition - window, has been introduced. The window

definition requires that the absolute resistance remain within

the stated window over the temperature range specified. The

resistance of the VHP100 resistor stays within a 60 ppm

window over the entire military temperature range of - 55 °C

to + 125 °C (figures 1 and 3).

POST MANUFACTURING OPERATIONS

ENHANCE THE ALREADY GREATER

STABILITY OF FOIL RESISTORS

These PMO operations are uniquely applicable to resistors

made of resistive foil and they take the already superior

stability of foil devices one step further. The PMO operations

described are not applicable to thick film, thin film, or wire.

They constitute an exercising of the resin that bonds the foil

to the substrate.

A window of 10 ppm is available for the laboratory instrument

range (+ 15 °C to + 45 °C); see figure 4 - type VHP101.

TCR TRACKING

Tracking of the VHP100 resistor is also vastly superior to

conventional precision resistors. Typical 5 ppm/°C precision

The exercises that are employed are (1) temperature cycling

(2) short time overload, and (3) accelerated load life.

resistors have

a worst-case tracking of 10 ppm/°C

TEMPERATURE CYCLING

(wirewounds, thick film, thin film) or a difference between

resistors of 1000 ppm (10 ppm/°C x 100 °C) when

temperature changes from + 25 °C to + 125 °C. For a

3 ppm/°C tracking (Vishay S102C) the difference will be

300 ppm (3 ppm/°C x 100 °C) for the same temperature

range. The VHP100 resistors will track to 60 ppm from - 55 °C

to + 125 °C, a five-fold improvement over the S102C resistor.

This exercise is done initially in the chip stage of all

production and will eliminate any fallout in the PMO cycling.

The cycling exercises the bonding resin and relaxes the foil

without reducing the bonding strength. A small reduction in

resistance is tolerable during this PMO operation.

SHORT TIME OVERLOAD

The STO operation is performed on all resistors during

manufacturing. Its function is to eliminate sports (if any) so

this PMO operation is further assurance.

ACCELERATED LOAD

10 ppm

Window

The standard load-life curve of a foil resistor exhibits a

change in the beginning and not much change after the first

100 h. This knee in the load-life curve can be removed so

that the resistor is now always on the flat part of the curve by

employing the PMO exercise of accelerated loading. How

much acceleration is a function of the application and should

be worked out between our applications engineering

department and your design team.

These same operations when applied to resistors of thick

film, thin film, and wire have vastly different consequences

and are applicable to foil only. They are an enhancement to

foil performance but can drive other devices out of tolerance

or open. The failure mechanisms in these other devises are

too numerous to discuss here but suffice it to say, foil is the

least affected by these PMO operations and they should be

considered when the level of stability required is beyond the

published limits for standard product.
