300144Z, 300145Z (Z-Foil)
Vishay Foil Resistors
Ultra High Precision Z-Foil Voltage Divider Resistors with TCR
Tracking to 0.1 ppm/°C, Power Coefficient Tracking of 5 ppm
at Rated Power, and Tolerance Match to 0.005 % (50 ppm)
Any value at any tolerance available within resistance range
INTRODUCTION
The 300144Z, 300145Z voltage dividers are the first choice
for ultra high precision, stability and reliable voltage division.
The Z-foil technology provides a significant reduction of the
resistive component’s sensitivity to ambient temperature
variations (TCR) and applied power changes (PCR).
0.05 ppm/°C absolute TCR removes errors due to
temperature gradients.
Models 300144Z and 300145Z offer low TCR (both absolute
and tracking), low power coefficient, excellent load life
stability, tight tolerance, excellent ratio stability, low thermal
EMF, low current noise and non sensitivity to ESD - all in one
package.
Model 300145Z is a pair-of 300144Z elements back to back
in a single molded package.
By taking advantage of the overall stability and reliability of
Vishay Bulk Metal® foil resistors, designers can significantly
reduce circuit errors and greatly improve overall circuit
performances.
Our application engineering department is available to
advise and make recommendations. For non-standard
technical requirements and special applications. Please
