Micro fuse.surface mount fuse manufacturer

　　Micro fuses are different from ordinary electronic components such as chip resistors and chip capacitors. Due to differences in manufacturers, their specifications vary greatly. In addition, actual installation can have a certain impact on the heat dissipation of printed boards and wiring. Therefore, the selection of micro fuses should ultimately be determined by the state of the product.

　　Miniature fuses are primarily used in digital cameras, laptops, mobile phones, and other electronic products. From traditional glass tube fuses to miniature fuses, the selection focus varies slightly due to differences in product technology. The selection of miniature fuses involves the following elements:

　　The normal operating current of the circuit should not exceed 75% of the rated current of the fuse.

　　2. Pulse, pulse current, surge current, starting current, and circuit transient values. Micro fuses are particularly concerned about this. Due to technological reasons brought about by small-scale, the impact resistance of miniature fuses is much lower than that of glass tube fuses or other larger fuses with the same rated current.

　　3. The size of the overload current and the minimum and maximum duration of the overload current in the circuit generally require oscilloscope testing and theoretical calculations to determine the size of the overload current. The basic requirement for fuses is that they should not be interrupted at any time and should be interrupted at an appropriate time.
