Selection & Application Guide
When selecting a surface mount maxi fuse holder, first confirm the fuse size, system rated voltage and working current, as well as the assembly process. For high-volume automotive electronic production, this SMD model is the preferred choice as it is fully compatible with standard SMT placement machines and reflow soldering processes. For high-temperature operating environments above 85℃, derate the current appropriately to ensure long-term reliability. Always match the automotive blade fuse rating with the actual working current of the circuit, reserving a 1.25-1.5 times safety margin to avoid premature failure or insufficient protection.
Application Scenarios
- Automotive electronics and new energy vehicle auxiliary circuits
- Truck, bus and commercial vehicle power distribution systems
- On-board chargers and DC-DC converter protection
- Industrial control power supplies and high-current PCB modules
- Telecom base stations and communication power equipment
- LED high-power drive power supplies
- High-density PCB designs with limited board space
Installation & Usage Notes
1. Select a matching MAXI automotive blade fuse with appropriate current and voltage rating before use.
2. Follow standard lead-free reflow soldering temperature profiles to avoid housing deformation or terminal oxidation caused by excessive temperature.
3. Do not use the fuse holder beyond its rated voltage and current range to prevent insulation breakdown and safety hazards.
4. Disconnect power before replacing the fuse to avoid electric shock and short-circuit damage.
5. Insert the fuse vertically to ensure full contact and firm clamping, preventing loosening under vibration conditions.
6. Store in a dry, dust-free and corrosion-free environment to prevent terminal oxidation and performance degradation.
