　　　　1. Rated voltage　　Rated voltage refers to the high voltage that can be withstood after the self recovery fuse is disconnected. The voltage borne by both ends of a self restoring fuse during the connection period is far less than its rated voltage. When selecting a self restoring fuse, it is generally required that its rated voltage be greater than the effective circuit voltage.　　2. Rated current　　The rated current is the high current that a self restoring fuse can operate for a long time. Assuming the protection current is Ir and the rated current of the self recovery fuse should be In, both should meet the following conditions: In=Ir/(fo * f1), where fo is the reduction rate for self recovery fuses of different specifications. For self recovery fuses of ICE specifications, no reduction rate can be added, that is, fo=1. For self recovery fuses of UL specifications, the reduction rate is fo=0.75. To consider the reduction rate after considering temperature, the higher the ambient te

How to choose a suitable waterproof fuse holder.pptc resettable fuse datasheet

　　　　In many electronic or electrical equipment products today, in addition to the main processing chips or other sensors, fuse holders are indispensable. From the perspective of the creation and invention of electricity, these products gradually occur in many electrical equipment components, becoming key gatekeepers to avoid ensuring application safety. There are many fuse holder products today, such as waterproof fuse holders. How do you choose the appropriate waterproof fuse holder?　　Firstly, what is the function of a waterproof fuse holder?　　Many people often confuse two types of products: fuses and fuse holders. In fact, this is not the same product. The former is a crucial electrode connection wire in all wire bases, while the latter is produced for easier installation of individual fuses and subsequent replacement. At present, there are many types of such products on the market, including panel mount and PCB types.　　Secondly, what are the characteristics of this type of product?

Principle of Resettable Current Fuses

　　　　Resettable current fuses offer a unique solution for protecting electrical circuits while providing the convenience of being reusable. Here's how they work.　　Resettable current fuses typically use a polymer-based material that changes its electrical resistance in response to an increase in current. When the current exceeds a certain threshold, the polymer material heats up and changes its state, increasing its resistance and limiting the current flow.　　Once the overcurrent condition is removed, the polymer material cools down and returns to its original low resistance state, allowing the circuit to resume normal operation. This resettable feature makes these fuses highly convenient as they do not need to be replaced like traditional fuses after each overcurrent event.　　The principle of operation of resettable current fuses is based on a combination of thermal and electrical properties of the polymer material. The material is designed to have a specific temperature coefficient of re

Some devices have a high starting current but a short starting time, so it is required that the protective characteristics of these devices should meet the needs of equipment operation. It is required

What is a fuse holder?lighting fuse block

　　　　Fuse holder refers to the holder used for installing fuses, which can be divided into panel mounted fuse holders, PCB mounted fuse holders, lead type fuse holders, and automotive fuse holders; Panel mounted fuse holder (mostly used for electrical equipment, such as power amplifier, DVD, speaker, Massage chair and other electrical equipment); Lead wire fuse holder (mostly used for connection of Small appliance and industrial machinery wire harness); PCB fuse holder (mostly used on the control board of Small appliance) and fuse clip (mostly used on the control board of Small appliance). Car fuse holders can be divided into lead type car fuse holders (commonly used in car and industrial machinery wiring harnesses); Panel mounted automotive fuse holders (commonly used in automotive appliances such as power amplifiers, refrigerators, DVDs, etc.) and automotive fuse clips. Fuse holders have requirements for current resistance, voltage resistance, and fire resistance, and generally requir
