Vishay Foil Resistors

Ultra High Precision Bulk Metal^®Z-Foil Technology

Power Current Sensing Resistors with TCR of ± 0.05 ppm/°C

and Power Rating up to 7 W

FEATURES

NEW

• Temperature coefficient of resistance (TCR):

± 0.05 ppm/°C (0 °C to 60 °C)

± 0.2 ppm/°C (- 55 °C to + 125 °C, + 25 °C ref.)

• Tolerance: ± 0.01 %

• Resistance range: 5 Ω to 100 KΩ

• 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)

INTRODUCTION

• Load life stability: ± 0.01 % (100 ppm) at 70 °C, 2000 h at

rated power

These Bulk Metal^®Z-Foil power current sensing resistors are

direct replacements for certain wirewound devices but

without the inductive characteristics of wirewounds. The

anodized aluminum housing is drilled and countersunk to

accept flat head screws for thermal mounting. Because the

device is internally Kelvin connected, there is no restriction

on the lead lengths as would be the case if this were a two

terminal device. Frequently used in YIG oscillator circuits

these devices contribute to superior frequency stability.

• Electrostatic discharge (ESD) 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 stabilization time < 1 s (nominal value achieved

within 10 ppm of steady state value)

• Thermal EMF: 0.05 µV/°C typical

• Voltage coefficient: < 0.1 ppm/V

• Non-inductive: < 0.08 µH

• Pattern design minimizing hot spots

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

• Prototype quantities available in just 5 working days

or sooner. For more information, please contact

Vishay Foil Resistors

POST MANUFACTURING OPERATIONS (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.
