Surface Mount Chip, ± 5 ppm/°C TCR, 0.01 % Tolerance

PLT

Vishay Thin Film

Vishay’s proven precision thin film wraparound resistors will

meet your exact requirements. These resistors are ideal for

precision applications requiring low noise, stability, 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.
