Ultra Precision Low TCR Thin Film Resistor, Surface Mount Chip,

± 2 ppm/°C TCR, 0.01 % Tolerance

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.

CONSTRUCTION

FEATURES
