Z Series (Z-Foil)

Vishay Foil Resistors

Ultra High Precision Z-Foil Resistor with TCR of ± 0.05 ppm/°C,

Tolerance of ± 0.005 % (50 ppm), Load Life Stability of ± 0.005 %,

ESD Immunity up to 25 kV and Thermal EMF of 0.05 µV/°C

FEATURES

• Temperature coefficient of resistance (TCR):

NEW

- ± 0.05 ppm/°C typical (0 °C to + 60 °C)

- ± 0.2 ppm/°C typical (- 55 °C to + 125 °C,

+ 25 °C ref.) (see table 1)

• Rated power: to 1 W at + 125 °C

• Resistance tolerance: to ± 0.005 % (50 ppm)

• Load life stability: to ± 0.005 % at 70 °C, 2000 h or to

INTRODUCTION

±0.015% at 70°C,10000 h (see table 4)

The Bulk Metal^®Foil resistor is based on a special concept

• Resistance range: 10 Ω to 600 kΩ

where a proprietary bulk metal cold rolled foil is cemented to

a ceramic substrate. It is then photoetched into a resistive

pattern. Furthermore, it is laser adjusted to any desired value

and tolerance. Because the metals used are not drawn,

wound or mistreated in any way during manufacturing

process, the Bulk Metal Foil resistor maintains all its design,

physical and electrical characteristics while winding of wire

or sputtering does not. Z foil resistors achieve maximum

stability and near-zero TCR. These performance

characteristics are built-in for every unit, and do not rely on

screening or other artificial means for uniform performances.

• 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)

• Total accumulated change in resistance over life (EOL)

< 0.05 % (or better with PMO)

• Electrostatic discharge up to 25 000 V

• Non-inductive, non-capacitive design

• Rise time: 1 ns effectively no ringing

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

• Thermal EMF: 0.05 µV/°C typical

The stability of a resistor depends primarily on its history of

exposures to temperature. Stability is affected by:

1. Changes in the ambient temperature and heat from

adjacent components (defined by the Temperature

Coefficient of Resistance, or TCR)

• Voltage coefficient: < 0.1 ppm/V

• Low inductance: < 0.08 µH typical

2. Destabilizing thermal shock of suddenly-applied power

(defined by the power coefficient, or PCR)

• Thermal stabilization time < 1 s (nominal value achieved

within 10 ppm of steady state value)

3. Long-term exposure to applied power (load-life stability)

4. Repetitive stresses from being switched on and off

• Pattern design minimizing hot spots

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

In very high-precision resistors, these effects must be taken

into account to achieve high stability with changes in load

(Joule Effect) and ambient temperature.

• Matched sets are available per request

(TCR tracking: to 0.5 ppm/°C)

• Prototype quantities available in just 5 working days

or sooner. For more information, please contact

foil@vishaypg.com

Vishay’s new Z-Foil technology provides an order of

magnitude reduction in the Bulk Metal Foil element’s

sensitivity to temperature changes - both external and

internal. This technology provides an absolute TCR of

± 0.05 ppm/°C typical (instrument range: 0 °C to +60 °C),

± 0.2 ppm/°C typical (military range: - 55 °C to + 125 °C,

+ 25 °C ref), and a PCR of 5 ppm at rated power.

• Load life ΔR maximum can be reduced significantly

with our post manufacturing operations (PMO) see

page 4 for details

In order to take full advantage of this TCR improvement, it is

necessary to take into account the differences in the

resistor’s response to each of the above-mentioned effects.

The Z series has been developed to successfully deal with

these factors.

STANDARD OPERATIONS AND TEST

CONDITIONS

A. Standard Test Operations:

POST MANUFACTURING OPERATIONS OR

PMO

Many 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. Vishay 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 applications

engineering for assistance in choosing the PMO operations

that are right for their application.
