Littelfuse's axial and radial fuses have demonstrated significant advantages in the field of circuit protection due to their structural design, performance optimization, and wide applicability. The following provides a detailed analysis from three aspects: technical characteristics, application scenarios, and industry adaptability:
1、 Structural diversity and installation flexibility
Adapt to multiple circuit layouts
Axial type (such as PICO series) and radial type fuses provide through-hole installation designs, compatible with high-density circuit board layouts of traditional industrial equipment, simplifying welding processes and improving mechanical stability. For example, the PICO series saves space with its ultra small axial structure (diameter only 5mm), making it suitable for miniaturization scenarios such as smart homes and medical devices.
High voltage and high current support
Some axial/radial fuses are designed specifically for high voltage scenarios, such as hazardous area fuses that support high voltage applications from 400V to 600V and are UL certified to meet the high reliability requirements of industrial power systems (such as UPS and base station power supplies).
2、 High reliability and security protection
Extreme environmental adaptability
Adopting ceramic or epoxy resin packaging (such as 835 series), the working temperature range covers 55 ° C to 150 ° C, and can withstand high temperature, high humidity, and vibration environments, suitable for harsh scenarios such as automotive engine compartments and industrial equipment.
Surge tolerance and breaking capacity
Some models (such as hazardous area fuses) have high surge capacity (such as 1.5kA 8/20 μ s pulse), reducing false tripping phenomenon, and can quickly melt in case of short circuit or lightning strike, avoiding equipment damage or safety accidents.
Special design for hazardous environments
For flammable and explosive environments such as petrochemicals and mining, the barrier mesh axial fuse is designed with a special structure to provide additional electric shock protection and explosion-proof functions, ensuring the safety of personnel and equipment.
3、 Industry coverage and high efficiency
Multi domain application adaptation
Automotive Electronics: Plug in axial fuses (such as the 089107.5NXT series) support in car chargers (OBC) and battery management systems (BMS), certified by AECQ200 to ensure the stability of high-voltage systems in electric vehicles.
Industrial power: The HVAC series fuses are designed specifically for HVAC systems, resistant to high temperatures and high current shocks, and suitable for industrial frequency converters and high-power battery systems.
Consumer electronics: Miniature fuses (such as the 392 series) protect smart home appliances and power adapters with low internal resistance and high-precision melting characteristics.
Cost effectiveness and easy maintenance
Axial/radial fuses adopt standardized packaging, support automated production (such as SMT process), and reduce manufacturing costs; Some models support vertical installation and are designed with epoxy resin coating insulation to simplify maintenance processes.
4、 Environmental compliance and certification advantages
The entire series of products comply with RoHS and lead-free standards, and have passed international certifications such as UL and IEC (such as UL24814), meeting global environmental regulations and industry standards. They are suitable for export electronic equipment and green energy projects.
The core advantages of Lite axial/radial fuses lie in their structural adaptability, high reliability in extreme environments, and wide coverage across industries. Its technological highlights include explosion-proof design for hazardous scenarios, high wave tolerance, and miniaturized packaging to meet the needs of modern electronic devices. Whether it is traditional industrial equipment or emerging new energy vehicle fields, Lite can provide targeted circuit protection solutions.
