Littelfuse Fuse selection
The fuse is a very important and indispensable part of the circuit protection, which automatically fuses when the current is too large, so as to avoid equipment damage or fire caused by electricity through the load or short circuit. Littelfuse, the global leader in circuit protection, offers a wide range of fuse products to meet the needs of every application. Faced with a wide range of products, how to choose the right Littelfuse fuse has become a difficulty for many engineers and technicians.
The first step in choosing a Littelfuse fuse is to identify your requirements. This includes the following aspects:
Application: There are a variety of applications of fuses, such as consumer electronics, automotive electronics, industrial control, power supplies, and so on. Different applications have different performance requirements for fuses, such as high temperature and vibration resistance in automotive electronics, while consumer electronics pay more attention to miniaturization and low power consumption.
Voltage and current: Voltage and current are the most basic parameters for selecting fuses. The rated voltage of the fuse must be higher than the operating voltage of the circuit, and the rated current is selected according to the maximum operating current of the circuit.
Fuse characteristics: Littelfuse offers a variety of fuses with fuse characteristics, such as quick break, slow break, time delay, etc. Quick-break fuses are suitable for protecting circuits that are sensitive to current changes, while slow-break fuses are suitable for circuits that allow a certain overload current.
Package size: Littelfuse offers fuses in a variety of package sizes, such as patch type, plug-in type, lead type, etc. Selecting the right package size can facilitate the circuit and installation.
