Frequently Asked Questions
How does the 100ppm/°C temperature coefficient of RNF14FTD20K0 affect precision measurement designs across temperature?
The RNF14FTD20K0 has a 100ppm/°C temperature coefficient, meaning its 20K ohm resistance changes by approximately 2 ohms for every 1°C shift. Over a typical industrial temperature range of -40°C to 85°C, the total resistance drift is within ±2.5K ohms from nominal, which is acceptable for most analog signal conditioning and voltage divider applications but may require compensation in ultra-precision references requiring drift below 25ppm/°C.
What makes the flame-proof construction of RNF14FTD20K0 important for industrial and safety-critical designs?
The flame-proof construction of RNF14FTD20K0 means the resistor body is designed to contain any internal ignition and prevent flame propagation if the component fails due to overload. This is required in applications subject to IEC 60065, UL, or similar safety standards, including medical power supplies, industrial control panels, and consumer appliance circuits where resistor failure under fault current must not initiate a fire hazard in the surrounding assembly.
How does the 1% tolerance of RNF14FTD20K0 compare to 5% carbon film resistors for precision voltage dividers?
The RNF14FTD20K0 offers 1% tolerance on its 20K ohm resistance, meaning the actual value stays within 19.8K to 20.2K ohms. Carbon film resistors with 5% tolerance would span 19K to 21K ohms, creating up to 5% error in a voltage divider ratio. For precision analog references and feedback networks where accuracy better than 2% is needed, the 1% metal film RNF14FTD20K0 is the correct choice over lower-cost 5% alternatives.
What lead time and compliance documentation should buyers expect when ordering RNF14FTD20K0 in production quantities?
The RNF14FTD20K0 typically carries a factory lead time of 21 weeks from Stackpole Electronics through authorized distributors. Buyers should request RoHS and REACH compliance certificates, which are supported per the JESD-609 e3 code, and confirm the estimated 9-year time-to-end-of-life (YTEOL) rating when building long-production-life programs. For urgent requirements, distributor stock at quantities under 10,000 units is generally available at shorter lead times.
