INTRODUCTION
The Z-foil technology provides a significant reduction of
the resistive component’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 Vishay‘s revolutionary Z-foil technology.
0.05 ppm/°C absolute TCR removes errors due to
temperature gradients.
Models 303119Z and 303119 are surface mount chip
resistors designed with 4 pads for Kelvin connection.
Utilizing Vishay’s Bulk Metal
®
Z-foil as the resistance
element, 303119Z provides performance capabilities far
greater than other resistor technologies can supply in a
product of comparable size.
These small devices dissipate heat almost entirely through
the pads so surface mount users are encouraged to be
generous with the board’s pads and traces. Gold
terminations are available as well.
Our application engineering department is available to
advise and to make recommendations.
Vishay Foil resistors are not restricted to standard values,
specific “as required” values can be supplied at no extra
cost or delivery (e.g. 1.234
Ω
vs. 1
Ω)
Tolerance: to ± 0.5 %
Power coefficient “ΔR due to self heating”: 5 ppm at rated
power
Load life stability: 0.05 % at 70 °C, 2000 h at rated power
Electrostatic discharge (ESD) up to 25 000 V
Short time overload < 0.02 %
Power rating: 0.5 W at + 70 °C (figure 1)
Non inductive, non capacitive design
Rise time: 1 ns effectively no ringing
Current rating: 5 A maximum
Current noise: < - 40 dB
Voltage coefficient: < 0.1 ppm/V
Non inductive: < 0.08 µH
Non hot spot design
For prototypes units, append a “U” to the model number
(example: 303119ZU). These units have all of the table 2A
(page 3) 100 % tests performed, with no destructive
qualification testing required (table 3A, page 3). For more
