Heating Element Fuse

Jaye Heater Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of heating element fuse in China, also supports custom service. Welcome to wholesale high quality heating element fuse at competitive price from our factory.

The basic components of a heating element fuse are made up of three parts: one is the melting part, which is the core of the fuse and cuts off the current when it blows. Be as small and consistent as possible, and most importantly, have consistent fusion properties. Household fuses are usually made of lead-antimony alloys. Good conductivity should not produce significant mounting contact resistance; the third part is the bracket part. The melt of a fuse is usually thin and soft. The function of the bracket is to fix the melt and make the three parts a rigid whole, which is easy to install and use. It must have good mechanical strength, insulation, heat resistance and flame retardancy, and must not be broken, deformed, burned and burned during use. short circuit.

Shape of heating element fuse:

1. Filamentous. Early original fuses, direct screw locking, used in old switches and sockets of all sizes.

2. Plate (bare plate). Easier to use than old filigree.

3. Glass tube. There are several different sizes and are commonly found in electronics.

6.3 x 32 mm (diameter x length)

5 x 20mm

4. Ceramic tube. There are several different shapes and sizes to avoid glass bursting.

5. Plastic plates with metal plate pins: automotive fuses.

Surface-Component (SMD) type.

7. Cylindrical, plug-in: directly soldered to the circuit board for use inside the product.

Classification of heating element fuses:

According to the protection form, it can be divided into: overcurrent protection and overheating protection. Fuses used for overcurrent protection are common fuses (also known as current limiting fuses). Fuses used for overheating protection are often called "thermal fuses". Thermal fuses are divided into low melting point alloy type, temperature trigger type and memory alloy type. Pots, electric stoves, transformers, motors, etc. ; it responds to an increase in the temperature of the appliance, regardless of the operating current of the circuit. It works differently than a "current limiting fuse").

According to the volume can be divided into: large, medium, small, micro. According to the rated voltage, it can be divided into: high voltage fuse, low voltage fuse and safety voltage fuse.

According to the shape, it can be divided into: flat head tubular fuse (can be divided into inner welding fuse and outer welding fuse), pointed tubular fuse, broken head fuse, spiral fuse, blade fuse, flat fuse , wound fuse, chip fuse.

According to the fusing speed, it can be divided into: ultra-slow fuse (generally expressed by TT), slow fuse (generally expressed by T), medium-speed fuse (generally expressed by M), fast fuse (generally expressed by F) , Special fast fuse (generally represented by FF).

According to the standard, it can be divided into: European fuse, American fuse, Japanese fuse.

According to the type, it can be divided into: current fuse (chip fuse, miniature fuse, plug-in fuse, tubular fuse), thermal fuse (RH [square type], RP [resistance type], RY [metal case]), resettable fuse (Inserts, Laminations, Patches).

According to size, it can be divided into: SMD type 0603, 0805, 1206, 1210, 1812, 2016, 2920; non-surface mount type Φ2.4×7, Φ3×7, Φ3.6×10, Φ4.5×15, Φ5.0×20, Φ5.16×20, Φ6×25, Φ6×30, Φ6×32, Φ8.5×8, Φ8.5×8×4, Φ10×38, Φ14×51.
