Selection of Fuses in Small Home Appliance PCB Board
The Fuses commonly used in PCB boards of small household appliances use self-recovery fuses to protect the circuit. The selection of self-recovery fuses in small household appliances can be divided into the following steps:
Firstly, determine the working voltage of the self-recovery fuse;
2. Based on the actual average operation of different products, determine whether the self-recovery fuse is the inactive current;
3. The maximum current ratio, temperature, and other parameters of household small appliances in actual work, as well as the time required for self-recovery fuse self-correction (self-recovery fuse action current amplification or reduction);
4. Revise it to an actual experiment and ensure that there is no false protection work, but it is necessary to self-recover the fuse parameters within the specified time and protect the motor from stalling. The change in the thermistor of a small motor is an easy choice, but after repeated experiments, the thermal resistance of the motor varies significantly
During the experiment, self-restore the resistance value of the fuse to determine the upper and lower limits.

Calculation Method for Melt Current of Fuse Fuses
The current of a fuse includes two aspects, one is the rated current of the fuse tube, and the other is the rated current of the melt, which cannot be confused.
The Installation Precautions for Current Fuses
The installation of current fuses is crucial for ensuring the safety and proper functioning of electrical circuits. Here are some important installation precautions to keep in mind.
Precautions for Selecting Chip Fuses
With the development of highly integrated electronic products such as digital cameras, laptops, and smartphones, and urgent need for factories to adopt full automation to reduce high labor costs in the market environment. Chip fuses are widely used in overcurrent protection applications, but due to differences in technology, they have different advantages compared to plug-in self-recovery fuses. At the same time, chip fuses also have some of their own weaknesses.

Temperature Characteristics of Current Fuses
Current fuses exhibit specific temperature characteristics that play a crucial role in their performance and reliability. The behavior of a current fuse in response to temperature changes is determined by several factors.
Factors Affecting the Lifespan of Fuses and Their Evaluation
In this article, XC tells factors that affect the lifespan of fuses.
Selection of Current Fuses in Automotive Circuits
In automotive circuits, the selection of current fuses is of great significance for ensuring the safe operation of the vehicle. There are several key factors to consider when choosing a current fuse for an automotive circuit.
Explanation of Parameters in the PPTC Specification for Self Healing Fuses
This is very simple. As long as you know the meaning represented by the parameters in the specification book, you can clearly and quickly view the PTC specification book for self recovery fuses.
Professional Knowledge of Self-healing Fuses
The operating principle of a self-healing fuse is a dynamic balance of energy. The current flowing through the self-healing fuse generates a certain amount of heat due to the thermal effect of the current (self-healing fuses all have resistance values), and the generated heat is completely or partially dissipated into the environment. The heat that is not dissipated will increase the temperature of the self-healing fuse components. The temperature during normal operation is relatively low, and the heat generated and dissipated reaches a balance.
Encapsulation Forms of Current Fuses
The encapsulation of current fuses is an important aspect that affects their performance, durability, and safety.
Self Recovery Performance and Working Process of Self Recovery Fuses
Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self-recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications.
Essential Knowledge for Selecting Automotive Fuses
When a certain overload current passes through, the heat generated is radiated to the surrounding environment through the melt and shell, and the heat dissipated through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the melt temperature can increase; When the temperature reaches or exceeds the melting point of the melt, the melt melts, fuses, and cuts off the current, playing a role in safety protection of the circuit.
The Role of Current Fuses in Smart Meters
Current fuses play a vital role in smart meters. Firstly, they provide protection against overcurrent events. Smart meters are used to measure and manage electricity consumption accurately. However, electrical circuits can sometimes experience sudden surges in current due to various reasons such as power outages and subsequent restoration, short circuits in the electrical grid, or the malfunction of connected electrical appliances.
Electric Vehicle Malfunctions Due to Lack of Fuses or Diodes
With the development of life, electric vehicles have also become popular. In order to facilitate people‘s travel, many families have started to use electric vehicles, which are convenient and affordable. However, there are still many unknown problems that arise during use. Today, the editor will briefly talk about the structural issues of electric vehicles.
