Corrosion resistance for demanding environments
New chip resistors can cope with operational temperatures from -55C to +155C
RS Components has added new ultra-high precision chip resistors to its 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 is said to have a far greater electrolytic corrosion resistance than its predecessor – the RN73 series – which, says RS, “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. Also, they have a maximum moisture tolerance of ±0.25%, at 85% relative humidity for a period of 1000 hours at +85°C.
