Automotive-grade thin film wide termination chip resistors now available

Applications for surface mount chip resistors with high power needs typically mean higher circuit temperatures due to thermal resistance limitations. One of the most common and economical options for decreasing the effects of power is wide terminations, which generally reduces the hot spot temperature of a given chip size by 30% to 40%. However, for precision tolerance and TCR requirements or high-reliability applications, the options for wide termination chip resistors become limited.

Stackpole Electronics’ new RNWA is a thin-film chip resistor with all the benefits of wide terminations. It is capable of tolerances of 0.1% and TCR of as low as 25ppm. Also, it is automotive grade, which supplies an extra level of long-term stability and reliability and is resistant to sulphur.
