VCS1625ZP (Z-Foil)
Vishay Foil Resistors
Ultra High Precision Z-Foil Surface Mount Current Sensing Chip Resistor
with Power Rating to 1 W and Temperature Coefficient of Resistance of
:
± 0.05 ppm/°C and Power Coefficient of 5 ppm at Rated Power
NEW
INTRODUCTION
The Z-foil technology provides a significant increase of
stability of resistance value’s sensitivity to ambient
temperature variations (TCR) and applied power changes
(PCR). Designers can now guarantee a high degree of
stability and accuracy in fixed-resistor applications using
solutions based on VPG’s revolutionary Z-foil technology.
Model VCS1625ZP is a surface mount chip resistor designed
with 4 pads for Kelvin connection. Utilizing VPG’s Bulk
Metal
®
Z-foil as the resistance element, it provides
performance capabilities far greater than other resistor
technologies can supply in a product of comparable size.
0.05 ppm/°C typical TCR removes errors due to temperature
gradients.
This small device dissipates heat almost entirely through the
pads so surface mount users are encouraged to be generous
with the board’s pads and traces.
The four terminal device separates the current leads from the
voltage sensing leads. This configuration eliminates the
effect of the lead wire resistance from points A to B and C to
D, allowing low TCR current sensing.
Temperature coefficient of resistance (TCR):
± 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)
Resistance range: 0.3
to 10
(for
higher or
lower values please contact us)
Vishay Foil Resistors are not restricted to standard values,
we can supply specific “as required” values at no extra cost
or delivery (e.g. 1.234
vs. 1
)
Resistance Tolerance: to ± 0.2% (0.05% and 0.1% are
also available)
Power coefficient “R due to self heating”: 5 ppm at rated
power
Load life stability: 0.015 % at 70 °C, 2000 h at rated power
Electrostatic discharge (ESD) at least to 25 000 V
Short time overload < 0.005 %
Thermal stabilization time < 1 s (nominal value achieved
within 10 ppm of steady state value)
Power rating: 1 W at + 70 °C (figure 1)
Non inductive, non capacitive design
Rise time: 1 ns effectively no ringing
Current rating: 1.8 A maximum
Current noise: 0.010 µV
RMS
/V of applied voltage(< - 40 dB)

Non inductive: < 0.08 µH
Non hot spot design
Prototype quantities available in just 5 working days or
sooner.
For higher temperature application above +150 °C and for
better performances please contact us.
