A high‑stability precision metal film resistor with 10Ω to 1MΩ range, 0.25W–1W rating, ultra-tight ±0.05% tolerance, low ±5 ppm/°C TCR, and durable through-hole, moisture-resistant construction.
The RESI MMFR Series is a precision metal film resistor designed for electronic circuits requiring low temperature drift, high stability and accurate resistance performance.
Manufactured using 96% alumina ceramic cores with precision metal film deposition technology, the MMFR Series is laser trimmed to achieve accurate resistance values across a range from 10Ω to 1MΩ.
With a low TCR down to ±5ppm/°C, tolerance options as tight as ±0.05% and load life stability of ±0.05%, the MMFR Series is well suited to precision circuits where long-term resistance stability is critical.
Its through-hole pin structure also helps reduce the influence of PCB stress on resistor performance, making it a reliable choice for demanding measurement and control applications.
