• Flame-retardant coating standard for safety compliance
• Low temperature coefficient for consistent performance under thermal variation

Applications

• General purpose precision circuits
• High-accuracy signal conditioning
• Test and measurement equipment

Procurement Notes

Verify the specific suffix code against official datasheets to confirm tolerance and TCR specifications. Ensure the ordering part number matches the required ±0.1% tolerance and ±25ppm/°C coefficient. Confirm RoHS compliance status and packaging type requirements prior to purchase.

Selection Notes

Select this component when high precision and low drift are critical. The ±0.1% tolerance and ±25ppm/°C TCR distinguish it from standard 1% variants. Verify that the 250V working voltage meets circuit requirements and that the axial package fits the PCB layout constraints.

Part Context

This resistor belongs to the RNF series of general-purpose metal film resistors. The series offers various tolerance and TCR combinations. The RNF14 designation indicates a 1/4W power rating in an axial leaded package suitable for through-hole mounting technologies.
