Technical FAQ for R&D and Procurement
Q: What are the differences between the MF and MF-S Series, and which model should be selected for flameproof applications?
A: MF is the standard-size metal film resistor, while MF-S is the mini-size version designed for high-density PCB layouts. For applications with higher safety requirements, the FMF type is recommended. It features an external silicone flameproof coating to provide enhanced safety in high-temperature environments.
Q: What T.C.R and resistance tolerance options are available?
A: The standard T.C.R for this series is ±100PPM. For higher-precision signal processing applications, 15, 25, or 50 PPM options are also available, while the FMF 5W model is rated at 100ppm. Standard resistance tolerance is ±1%, with customized options ranging from 0.1% to 5% depending on customer requirements.
Q: What are the available power ratings and resistance ranges for these metal film resistors?
A: This series supports power ratings from 1/8W to 2W at an ambient temperature of 70°C. Standard resistance values range from 10R to 1Meg in accordance with the E24 and E96 series, meeting the design requirements of a wide range of precision electronic circuits.
