Part 1: Overview of BEL Brand and ProductsBEL (Bel Fuse Inc.) is a globally leading provider of electronic connectors, circuit protection, and power solutions, with products including automotive-grade fuses, Ethernet connectors, signal filters, and more. In the field of automotive electronics, BEL offers a variety of key components to ensure the reliable operation of in-vehicle communication systems, EV/HEV systems, and in-vehicle power systems.
Typical Applications in Automotive ElectronicsAutomotive-grade fuse and PTC self-recovering fuse
BEL's 0ZRS series PTC self-recovery fuses, compliant with AEC-Q200 automotive grade standard, can withstand up to 32 V DC, with current range from 500 mA to 10 A, suitable for key parts including main battery packs and automotive auxiliary circuits, enhancing system safety and stability.
2. High-voltage fuse and protection for EV/HEV
BEL provides high-voltage SMD and ceramic fast-blow fuses for electric vehicles/hybrid electric vehicles (EV/HEV), covering 240-1000 V voltage applications. They are suitable for battery modules, charging stations, protective main circuits, and other scenarios, effectively ensuring the safety of the high-voltage system.
Car communication interface: high-speed Ethernet connector
The Stewart RJ45 connector of BEL fully conforms to the SAE/USCAR2-6 standard and is suitable for in-vehicle Ethernet communication, ADAS radar modules, vehicle-mounted cameras, vehicle computing units, etc., providing high-speed and stable data transmission capability.
Three, the trend of domestic connectors replacing in the field of automotive electronicsAlthough the BEL products have advantages in terms of performance and certification, domestically produced connectors are rapidly catching up, especially in the following directions:
●Cost and response advantages: Domestic manufacturers have geographical advantages, respond quickly, and have more competitive costs.
●Research and certification catch-up: Some domestic brands have begun to invest in AEC-Q vehicle-grade certification, and expand high-speed signal and PoE connector technology.
Local supply chain collaboration: localization of production and enhancement of supporting capabilities contribute to improving the supply guarantee and customization ability of vehicle manufacturers.
BEL covers key applications such as battery protection, electrical safety, and vehicle communication in the automotive electronics field through high-reliability connectors and fuse products; while domestic connectors are gradually gaining a foothold in these areas by leveraging their cost, responsiveness, and localization advantages. In the future, after continuously strengthening standard certification and technological accumulation, domestic brands are expected to achieve more replacements in various automotive electronics niche scenarios.
