LF 392 Series Small Current fuses

Product Item: LF 392 Series Small Current fuses
Category: Current fuse

Fuse shape
1. Filiform. Earlier original types of fuses were directly screw-locked and used for old switches and sockets of various sizes.
2. Flaky (naked). Chip fuses are more convenient to use than older wire types.
3. Glass tube. There are several different sizes, common in electronics.
6.3 x 32 mm (diameter x length)
5 x 20 mm
4. Ceramic tube. There are several different shapes and sizes to prevent glass from bursting.
5, plastic sheet with metal flake pin: Automotive fuse.
6. Surface Mount Device (SMD) type.
7. Cylinder-shaped, plug-in type: directly soldered to the circuit board, used in the product.

Fuse sign
Most fuses are marked on the body or with end caps and markings indicating their rating. But "chip type" fuses have little or no marking, making identification very difficult.
Fuses may exhibit similar and significantly different characteristics, identifying their markings. Fuse marking usually conveys the following information:
Ampere fuse rating
Voltage level fuse
Time-current characteristics, ie speed fuse
Approved by national and international standards bodies
Manufacturer / Product Number / Series
Fusing capacity
