Precision resistors need more than tight tolerance and low temperature coefficient. They need to remain stable in value for the whole life of the product. TT Electronics is continually innovating in processes and materials to deliver new precision resistors which make this possible.

WIN series thin film chip resistors use an advanced metal film technology to provide high levels of reliability and stability for precision resistor applications. The water insoluble nitride film avoids the moisture vulnerability problems of nichrome and passivated nichrome technologies. WIN series delivers very low and predictable life drift and high reliability even under conditions of high humidity and in the event of damage to the component coating layer. This is due to its ability to self-passivate by forming a very thin, highly stable oxide layer.

Available in 0603, 0805 and 1206 sizes at 0.1W, 0.25W and 0.33W respectively, the series offers resistance values from 10R to 1M0 with a tolerance of ±0.1% and TCR of ±25ppm/°C.
