0.01% 2ppm/°C SMD resistors are REACH and RoHS-compliant, and Pb-free

A part of its RNCF vary, these highest spec elements don’t come within the huge worth vary of lesser RNCF resistors.

For instance: 0402 varieties can be found between 49.9Ω and 4.99kΩ, then 2512 has the widest span of choices,  between 24.9Ω and 100kΩ.

Relying on measurement, most scores are 100mW and 50V (0402) to 500mW 150V (2512) – energy scores are at 70°C, after which linear derating is required to 0W at 155°C.

To specify the elements, an instance 0805 measurement 4.7kΩ resistor would have the half quantity RNCF0805TxW4K75, the place T=0.01% and W=2ppm/°C.

“The nichrome expertise of the RNCF offers distinctive stability and reliability with little or no resistance shift underneath regular load life and quick time overload situations,” in response to Stanckpole. “As well as, the RNCF is REACH compliant, RoHS compliant and totally lead free with out exemption.”

Functions are anticipated in medical tools, instrumentation, check tools and precision controls, however automotive use can be potential because the resistors are AEC-Q200 certified.
