25ppm, 0.1%, High Reliability – New High Precision Thick Film Chip Resistors from KOA

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 highaccuracy
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 and is available in 0603, 0805 and 1206 inch.


  • ±0.1%, ±0.25%, ±0.5% and ±1% tolerances available
  • ±25ppm/K, ±50ppm/K
  • ±0.2% ~ Long term stability
  • ESD stability of thick film resistors
  • Ideal for applications, where thin film is not suitable
  • Anti-Sulfuration type also available (RS73-RT)
