Self restoring fuse material has two optional types of radial leaded package and surface mount. Self recovery self recovery fuse features for a variety of design applications.
Plug and play applications include motherboards and peripherals that can be connected or disconnected from a computer port. Mouse, keyboard, audio, network, monitor and USB port connection equipment may fail, the connection cable may be damaged, there may be an error connection. Therefore, the ability to reset after correcting for the wrong connection is particularly attractive. Some of these applications use radial leaded devices, while others are more suitable for surface mount devices. When the power equipment is too high because of the fault caused by excessive current and the phenomenon of excessive current, self recovery fuse can protect the hard disk drive from damage. Hard disk drive applications typically use surface mount self recovery fuses.
Power supply equipment vulnerable to circuit failure. If no protective measures are taken, the current supplied by the power supply device may cause a low resistance fault. When there are multiple loads or multiple circuits, you can use an independent self recovery fuse to protect each load. The device is usually placed in the output circuit, and can be used in a radial lead or surface mount package.
The high temperature caused by the over current of the motor will cause damage to the winding insulation, and even cause the fault of the winding wire with small diameter. The self recovery fuse normally does not trip under normal starting current. Motors generally use radial lead type self recovery fuses for protection.
The transformer may be subject to over-current damage caused by a circuit fault, and the current limiting function of the self restoring fuse can provide protection. The self recovery fuse can be placed at the load end of the transformer, so as to minimize the influence of the circuit fault. Many applications use radial leaded or surface mount devices.
