Automotive-qualified components from KOA set new benchmarks for precision, stability and longevity

RS Components has added new, ultra-high precision chip resistors to its extensive passive portfolio. Optimised for industrial and automotive applications as well as for use in test instrumentation and audio equipment, the thin film element of KOA’s RN73R series exhibits a temperature coefficient of resistance that ranges from ±5ppm to ±100ppm. The new series has a far greater electrolytic corrosion resistance than its predecessor - the RN73 series - which ensures a more reliable device, especially in more demanding environments. Resistance values range from 10R to 1.5M dependent on chip size. Resistance tolerance levels are available down to ±0.05%.

The RN73R chip resistors are supplied in five sizes, from 0402 to 1210, with power ratings of up to 0.25W. Fully compliant with the AEC-Q200 automotive standard, these components can cope with operational temperatures from -55°C to +155°C. In addition, they have a maximum moisture tolerance of ±0.25%, at 85% relative humidity for a period of 1000 hours at +85°C.
