Frequently Asked Questions
1 What is the difference between an SMD Fuse and a Brick Fuse?
SMD Fuses are surface-mount components designed for compact handheld electronics and PCB-level protection, featuring a low-profile package. Brick Fuses offer a larger, diverse form factor (e.g., 2410, 1140/1032) and are suited for higher-power applications such as AC/DC power adaptors, telecom equipment, and LED lighting systems.
2 Are these fuses RoHS and Halogen-free compliant?
Yes. All four fuse types — SMD Fuse, Brick Fuse, Plastic Square Fuse, and Micro Fuse — are Lead-free and Halogen-free, and fully compliant with RoHS environmental regulations.
3 What certifications do these fuses carry?
The SMD Fuse holds AEC-Q200 Automotive Grade Certification, making it suitable for automotive applications. All fuses meet UL248-1 standard. The Plastic Square Fuse additionally complies with IEC60127 standards (931/932/936/938).
4 What operating temperature range do these fuses support?
The SMD Fuse supports an extended operating temperature range of -55°C to +150°C. The Brick Fuse, Plastic Square Fuse, and Micro Fuse all operate within -55°C to +125°C, making them suitable for a wide range of industrial and consumer environments.
5 What are the available dimensions 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, providing reliable protection for low-power applications such as emergency lights, LED power supplies, and medical devices.
6 Is the Brick Fuse compatible with automated soldering processes?
Yes. The Brick Fuse is designed to be compatible with both reflow soldering and wave soldering processes, making it highly suitable for automated PCB assembly in industrial and commercial manufacturing environments.
