Procurement Notes

Verify the specific suffix 'BE' against official datasheets to confirm the exact tolerance and temperature coefficient, as variations exist within the RNF series. Ensure the required packaging format matches available distributor stock options. Confirm lead times directly with authorized suppliers due to potential manufacturing delays.

Selection Notes

Select this component when tight tolerance and low temperature drift are critical. Compare against the RNMF series if space constraints require a smaller footprint. Verify that the 250V working voltage rating meets the circuit requirements. Consider alternative packaging if bulk quantities are needed versus tape and reel.

Part Context
