The FSD series fuse is a disposable tubular fuse with a glass tube quick break type. This update adds PSE safety certification, which has no impact on the performance, quality, and other aspects of the original product. Suzhou Walter Electronics is a professional manufacturer of fuse brands. This update is aimed at expanding our products to more countries and regions, making them more versatile and widely available.
With the increasing popularity of electronic equipment today, circuit protection is particularly important. Whether it is mobile phones, computers or household appliances, all kinds of components to ensure the safe and stable operation of the circuit. Its PTC thermistor, self-restoring fuse and fuse are three common circuit protection components, like the three musketeers of the guard circuit, each showing their powers to protect our electronic equipment from the threat of overcurrent.
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.
As a basic circuit protection element, fuse plays a very important role in circuit safety. The correct selection and use of fuses, and the accurate troubleshooting and troubleshooting of fuses when problems occur are very important to protect the stable operation of the circuit.
Fuse as a circuit protection element, its main function is to cut off the circuit through its own fusing when overload or short circuit occurs in the circuit to protect the circuit and equipment from overcurrent damage.
A fuse is an electrical component used to protect circuits and electrical equipment from overcurrent damage. The working principle is to automatically cut off the power supply when the current exceeds the set value, to avoid the power through the load, short circuit, failure and equipment damage. The fuse consists of a conductor part and a protective housing, and the conductor part is made of copper, silver, aluminum and other metals
The rated current of the fuse and the fusing current are two different concepts, which respectively represent the current bearing capacity of the fuse in normal operation and abnormal conditions. The rated current refers to the maximum current value of the fuse under specific conditions for a long time without blowing, and the blown current refers to the maximum current value of the fuse in a short period of time and eventually cause it to blow.
Self-restoring fuses, also known as Polymer Positive Temperature Coefficient (PPTC) fuses, are electronic protection components made of high molecular materials with low resistance under normal working conditions, and when the circuit produces overcurrent, the resistance value will increase rapidly due to the increase in temperature
In electronic circuits and protection, the Polyswitch plays a very important role. When the current is overloaded, the circuit is automatically disconnected, and the conductive function can be automatically restored after the abnormal situation is eliminated
In the field of protection of electronic equipment, self-restoring fuses play a very important role. This type of fuse opens the circuit when an overcurrent situation occurs, and automatically resets once the current returns to normal, thus avoiding damage to the equipment. What happens when the self-restoring fuse itself is short-circuited? This paper will explain this phenomenon and its potential consequences in detail, and discuss the corresponding solutions.
