Frequently Asked Questions
Q
What is the difference between an SMD Fuse and a Brick Fuse?
SMD Fuses are surface-mount devices designed for compact electronics such as laptops, cameras, and handheld devices, offering a low-profile package with high current capability. Brick Fuses, on the other hand, feature a larger and more diverse form factor (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 RoHS and Halogen-free compliant?
Yes. All fuse products listed — including the SMD Fuse, Brick Fuse, Plastic Square Fuse, and Micro Fuse — are Lead-free and Halogen-free, and fully comply with RoHS environmental standards.
Q
What certifications do these fuses carry?
All listed fuses comply with UL248-1 standard. The Plastic Square Fuse additionally meets IEC60127 standards (series 931/932/936/938). The SMD Fuse also carries AEC-Q200 Automotive Grade Certification, making it suitable for automotive-grade applications.
Q
What operating temperature range do these fuses support?
Most fuses support an operating temperature range of -55°C to +125°C. The SMD Fuse offers an extended range up to +150°C, making it ideal for high-temperature environments such as automotive and industrial applications.
Q
Is the Brick Fuse compatible with both reflow and wave soldering?
Yes. The Brick Fuse is fully compatible with both reflow and wave soldering processes, offering flexible integration into various PCB assembly workflows used in industrial, telecom, and consumer electronics manufacturing.
Q
What applications is the Micro Fuse best suited for?
The Micro Fuse (available in 2×7mm and 3.6×10mm sizes) is ideal for space-constrained and low-power applications, including emergency lighting, battery protection circuits, LED power supplies, LCD displays, and low-power medical equipment. Its ceramic body with epoxy coating provides reliable protection in compact designs.
