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.
