High-Stability Precision Thin Film Chip Resistor

The RESI PTFR Series is a precision thin film chip resistor designed for applications requiring high reliability, excellent long-term stability and low temperature drift. Manufactured using thin film technology, the series provides accurate resistance performance in compact SMD/SMT package sizes from 0402 to 1206. With a resistance range from 10Ω to 5.1MΩ, regular rated power from 0.06W to 0.25W, tightest tolerance of up to ±0.01% and TCR as low as ±5ppm/℃, the PTFR Series is suitable for precision electronic circuits where resistance stability is critical. Load life stability is specified at ±0.01%, supporting dependable performance in demanding designs. The series uses an enhanced protective coating to improve moisture resistance, with typical variation of less than ±0.025% after 1,000 hours of double 85 testing, making the product suitable for precision instruments, 5G systems and automotive applications. The series is also AEC-Q200 certified and RoHS compliant.
