Fuses play an important role in electrical and electronic engineering since it is designed to break an electrical circuit when too much current flows. 02153.15MXF160SPP is one kind of fuse with special application field and working principle.

The 02153.15MXF160SPP is an ultra fast-acting SMT cylindrical fuse, which has a single action characteristic. It is mainly used in protection of on-board components such as power regulators, telecom modules, and signal processors that require over-current and over-temperature protection. This fuse has an operating temperature range of -40°C - +125°C, and its surge current rating is 160A. Furthermore, it measures 15.24mm in length and 3.2mm in diameter. This makes 02153.15MXF160SPP suitable for a variety of applications.

The 02153.15MXF160SPP fuse has a unique working principle. It is composed of three conductor material electrodes, namely, a silver wire, a mica sheet, and a metal housing. When the over-current flows, the heat energy generated will be conducted to the mica sheet, which has a relatively low thermal conductivity. When it heats up, it will physically distort and cause internal thermal damage. This distortion or change in shape of the mica sheet causes an increase in the resistance of the circuit, causing the current to decrease and the circuit to be broken. When the current reaches a level below the normal level or the temperature drops, the mica sheet will return to its original shape, restoring the circuit.

In summary, the 02153.15MXF160SPP is an ultra fast-acting SMT cylindrical fuse with a single-action characteristic, suitable for protection of on-board components such as power regulators, telecom modules, and signal processors that require over-current and over-temperature protection. Its working principle involves the physical distortion of a mica sheet which increases the resistance of the circuit and causes the current to decrease, resulting in the circuit being broken.
