Technical FAQ for R&D and Procurement
Q: What are the main differences between the MOF and MOF-S Series, and what coating colors are available?
A: MOF is the standard-size metal oxide resistor, while MOF-S is the mini-size version designed for high-density circuit layouts. The entire series uses a standard gray silicone flameproof coating. For MOF-S mini-size models, a pink coating is also available upon customer request.
Q: What are the operating temperature and power rating ranges of these metal oxide resistors?
A: This series supports a wide operating temperature range from -55ºC to +200ºC, providing excellent electrical stability in high-temperature environments. Power ratings range from 1/4W to 5W at 70°C, making the series suitable for circuits requiring high durability and high-load performance.
Q: What are the resistance range and tolerance specifications for this series?
A: The standard resistance range is from 10R to 1M in accordance with the E24 series, with a standard resistance tolerance of ±5%. For circuit applications requiring higher precision, such as ±1%, please contact us for special customization inquiries.
