Frequently Asked Questions
Q1What is the difference between an SMD Fuse and a Brick Fuse?
An SMD Fuse is a surface-mount device designed for compact electronics such as notebooks, cameras, and handheld devices. It features a low-profile package and supports high current. A Brick Fuse, on the other hand, is larger and suited for higher-power applications such as AC/DC power adaptors, telecom equipment, and industrial systems, with diverse dimensional options like 2410 and 1140/1032.
Q2Are these fuses compliant with international safety standards?
Yes. All fuse products listed here comply with UL248-1 standards. The Plastic Square Fuse additionally meets IEC60127 standards (931/932/936/938). All products are Lead-free, Halogen-free, and ROHS compliant, ensuring they meet global environmental and safety requirements.
Q3What operating temperature range do these fuses support?
Most fuse products support an operating temperature range of -55°C to +125°C. The SMD Fuse offers an extended range of -55°C to +150°C, making it suitable for more demanding thermal environments such as automotive-grade applications.
Q4Is the SMD Fuse suitable for automotive applications?
Yes. The SMD Fuse is AEC-Q200 Automotive Grade Certified, which means it has been tested and qualified for use in automotive electronic systems. Its ceramic substrate printing process and wide operating temperature range make it reliable for such demanding environments.
Q5What dimensions are available 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 suitable for low-power applications such as emergency lighting, battery protection, and LCD displays.
Q6Can the Brick Fuse be used with both reflow and wave soldering processes?
Yes. The Brick Fuse is fully compatible with both reflow and wave soldering processes, providing flexibility for different PCB assembly methods. This makes it a versatile choice for a wide range of manufacturing environments and product designs.
