High voltage industrial environment Vishay, Eaton Bussmann 72V/125V high voltage support, anti pulse
Technological innovation: SMT fuses are developing towards high temperature resistance (>125 ℃), low resistance (<10m Ω), and ultra miniaturization (0201 package).
Market segmentation: New energy vehicles (accounting for 20%) and smart homes (accounting for 30%) are the main growth drivers.
Environmental requirements: The demand for lead-free/halogen-free patch fuses is increasing, and compliance with the RoHS directive has become standard.
Domestic substitution: Local brands such as Chengrun and Feihong are accelerating technological iteration, and the market size is expected to reach 15 billion yuan by 2025.
Global surface mount fuse brands are presenting a pattern of "high-end dominated by the United States and Japan, and cost-effectiveness focused by China and South Korea". The selection requires comprehensive voltage range (6V-600V), packaging matching (0402-2920), and scenario certification (automotive/medical). Chinese manufacturers, relying on localized services and cost advantages, continue to expand their market share in the consumer electronics and industrial sectors, and future technological breakthroughs will further enhance their global competitiveness.
