Mount Chip, ± 5 ppm/°C TCR, 0.02 % Tolerance
PLTT
Vishay Dale Thin Film
Vishay’s proven precision thin film wraparound resistors will
meet your exact requirements. These resistors are ideal for
use in oil industry precision applications requiring low noise,
long term stability under high temperature, ultra low
temperature coefficient of resistance, and low voltage
coefficient. The chip resistors are available in any resistance
ohmic value in the range specified below.
