China OC Fuse Suppliers - Over-Current Fuses for Safe, Reliable Circuit Protection from Leading Factory

Over-current fuses are innovative protective components specifically designed for surface mounting on circuit boards. Manufactured in China, these fuses provide numerous advantages over traditional through-hole options, such as a compact size and seamless compatibility with automated manufacturing processes. This space-saving design makes them ideal for modern electronic applications, ensuring efficient utilization of board space.
The primary purpose of OC fuses is to protect electronic equipment from damage due to overcurrent conditions. Our factory implements a thermal cutoff mechanism within these fuses to effectively interrupt the circuit when excessive current is detected. This quick response not only safeguards sensitive components but also significantly reduces fire hazards, thereby enhancing the safety and reliability of your devices. Partner with top suppliers in the industry to access high-quality over-current fuses tailored to your specific needs.

    Frequently Asked Questions
    Q What is the difference between an SMD Fuse and a Brick Fuse?
    SMD Fuses are surface-mount components designed for compact electronics such as handheld devices, notebook PCs, and battery packs, featuring a low-profile package and high current capacity. Brick Fuses are larger, offering diverse dimensions (e.g., 2410, 1140/1032) and are suited for higher-power applications such as AC/DC power adaptors, telecom equipment, and industrial systems.
    Q Are these fuses compliant with RoHS and halogen-free requirements?
    Yes. All fuse products — including the SMD Fuse, Brick Fuse, Plastic Square Fuse, and Micro Fuse — are Lead-free and Halogen-free, and comply with RoHS environmental standards.
    Q What operating temperature range do these fuses support?
    The SMD Fuse supports an extended operating temperature range of -55°C to +150°C, making it suitable for automotive-grade applications. The Brick Fuse, Plastic Square Fuse, and Micro Fuse all operate within -55°C to +125°C.
    Q What certifications do these fuse products carry?
    The SMD Fuse holds AEC-Q200 Automotive Grade Certification and meets UL248-1 standard. The Plastic Square Fuse complies with both UL248-1 (933) and IEC60127 (931/932/936/938). The Brick Fuse and Micro Fuse also conform to UL248-1.
    Q Is the Brick Fuse compatible with different soldering processes?
    Yes. The Brick Fuse is compatible with both reflow soldering and wave soldering processes, providing flexibility for various PCB assembly manufacturing requirements.
    Q What are the available sizes for the Micro Fuse?
    The Micro Fuse is available in two standard dimensions: 2×7mm and 3.6×10mm. Both variants feature a ceramic body coated with epoxy and are commonly used in emergency lighting, battery protection, LED power supplies, and low-power medical equipment.
