The SMF-L Series Power Metal Film Chip Resistors are designed for automotive electronics, EV control systems, industrial automation equipment, and power supply applications that require stable and reliable high power SMD resistors.
Built with advanced metal film technology and a flameproof UL94V0 molded structure, this metal film chip resistor series delivers excellent electrical stability, heat resistance, and moisture resistance under continuous high-load operating conditions. The SMT-compatible design also supports automated assembly processes, helping manufacturers in Japan and Korea improve production efficiency and reduce assembly costs.
As an automotive grade resistor, the SMF-L Series is AEC-Q200 qualified and suitable for demanding automotive and industrial applications including electric vehicle systems, motor drives, power modules, and industrial control equipment. Compared with standard chip resistors, the series provides enhanced insulation performance and a maximum working voltage of up to 500V for high-reliability electronic systems.
With a temperature coefficient of ±100ppm/℃ and an operating temperature range from -55℃ to +150℃, this high power SMD resistor maintains stable resistance performance even in harsh environments. The product is especially suitable for the Japanese and Korean electronics industries where long-term reliability and stable electrical performance are critical.
