300144Z, 300145Z (Z-Foil)
Vishay Foil Resistors
Bulk Metal® Foil Technology 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)
FEATURES
Temperature coefficient of resistance (TCR):
absolute: ± 0.05 ppm/°C typical (0 °C to + 60 °C)
± 0.2 ppm/°C typical (- 55 °C to + 125 °C,
+ 25 °C ref.)
TCR tracking: 0.1 ppm/°C typical
Tolerance: absolute and matching to 0.005 % (50 ppm)
Power coefficient tracking “R due to self heating”: 5 ppm
at rated power
Power rating: 0.2 W at 70 °C, for the entire resistive
element R1 and R2, divided proportionally between the two
values
