High Reliability New Size 0402 for High Precision Thick Film Resistors

KOA’s new RS73-series are ESD transient tolerant high precision and high reliability resistors using thick film technology.

With a T.C.R. down to ±25ppm and a tolerance as low as ±0.1%, the new RS73-series from KOA is ideal for precision designs such as high-accuracy sensing or voltage detection circuits in automotive, industrial and measuring applications, where ESD sensitivity is an issue.

The new RS73-series also features an excellent long term stability. The RS73-series is available in 0402, 0603, 0805 and 1206 inch.
