HZ Series (Z-Foil) with Zero TCR
Vishay Foil Resistors
New Generation of Secondary Standards Hermetically Sealed Construction Ultra High
Precision Z-Foil Technology Resistors with TCR of ꢀ0. ꢁꢁmꢂ/C, Tolerance of ꢀ0ꢀꢀꢃ ꢄ
and Load Life Stability of ꢀ0ꢀꢀ. ꢄ (Metrology, Laboratory, Instrumentation, Industrial)
FEATURES
Temꢁerature coefficient of resistance (TCR):
0.2 ppm/°C typical (- 55 °C to + 125 °C,
+ 25 °C ref.). For ultra high performances
(instrumentation and metrology) please refer to
the last page
Resistance range: 5 to 1.1 M (higher or lower values of
resistance available)
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)
Power coefficient “R due to self heating”:
5 ppm at rated power with the Z-Foil technology
Tolerance: to 0.001 % (10 ppm)
Load life stability to 0.002 % (20 ppm) at 25 °C, 2000 h
at rated power
Load life stability, can be considerably imꢁroved
through in-house stabilization
Shelf life stability: . ꢁꢁm for at least 6 years
(unaffected by humidity)
INTRODUCTION
The Z-Foil based oil filled, hermetically sealed HZ Series
resistors represent an industry breakthrough. The hermetic
sealing eliminates the ingress of moisture and oxygen, while
the oil acts as a thermal conductor, thus eliminating
long-term degradation elements of unsealed resistors, while
at the same time allowing the device to accept short periods
of overload without degradation.
The Z-Foil technology provides a significant reduction of the
resistive components, sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR). When
combined with the hermetic sealing and oil filling, the
HZ Series resistors become the most ꢁrecise and stable
resistors available. They are used as the most precise
secondary standards for ultra precision metrology.
Electrostatic discharge (ESD) up to 25 000 V
Power rating: 0.3 W to 2.5 W at + 25 °C (depending on
model - see table 2)
Non-inductive, non-capacitive design
Non hot spot design
Rise time: 1 ns effectively no ringing
Current noise: 0.010 µVRMS/V of applied voltage (< - 40 dB)
Thermal EMF: 0.05 µV/°C typical
Voltage coefficient: < 0.1 ppm/V
With accuracies of 0.001 % (10 ppm) and a resistance
range from 5 to 1.1 M and long term shelf life of less than
2 ppm, these devices are virtually secondary standards that
can be carried in sets for daily or periodic calibration of
factory measurement equipment.
Thermal stabilization time < 1 s (nominal value achieved
within 10 ppm of steady state value)
Non-inductive: < 0.08 µH
Terminal finish available: lead (Pb)-free or tin/lead alloy
Impervious to harmful environments - oil filled
Prototype quantities available in just 5 working days
or sooner. For more information, please contact
foil@vishaypg.com
The HZ Series is available with laboratory and metrology
level ꢁrecision and long-term stability with additional
in-house oriented ꢁrocesses such as: chiꢁ stabilization,
sꢁecial TCR ꢁlotting, additional treatments for ultra
stability and sꢁecial ꢁost manufacturing oꢁerations

POST MANUFACTURING OPERATIONS OR PMO FOR IMPROVED END OF LIFE
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. 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 amounts that are small but significant when compared to
the very tight tolerances. Users are encouraged to contact
Foil applications engineering for assistance in choosing the
PMO operations that are right for their application.

ULTRA HIGH PRECISION HERMETICALLY
SEALED RESISTORS
APPLICATIONS INCLUDE
Resistance standards
INTRODUCTION
The response of Vishay's hermetically sealed resistors under
variable conditions and stresses can be made better by
additional in-house oriented processes (PMO). Processes
such as short time overload, accelerated load life and
temperature cycling produce enhanced levels of accuracy,
stability and speed, offering immediate answers to many
resistor applications currently believed unsolvable, and
opens entirely new areas of design where the use of
resistors had not been considered.
Feedback devices for operational amplifiers
Precision voltage dividers
Meter multipliers
Precision bridge resistors
Decade voltage dividers
See table 5 for the improvement to expect in hermetically
sealed parts when calling for in-house oriented processes
