Chip fuse,self restoring fuse,chip current fuses,chip self recovery fuses

Normal current flow: Everyone needs to understand the normal current flow through the patch fuse in the circuit being used. Generally speaking, everyone needs to set a derating amount in advance, and then select according to the following basic principle: the normal current amount must be lower than the product of the rated current and the derating coefficient.

Fusing current: According to UL specifications and models, patch fuses should quickly fuse at twice the rated current. But in most cases, to ensure stable fusing, we suggest that the fusing current should be greater than 2.5 times the rated current. In addition, when the time of the circuit breaker is important, the judgment must also be made by referring to the circuit breaker performance diagram provided by the manufacturer.

Open circuit voltage: The open circuit voltage should usually be selected below the rated voltage. For example, when using a Chip fuse with a rated voltage of DC24V in an ACl00V circuit, it may ignite the chip fuse or cause the fuse to crack.

The ambient temperature of the fuse should be within the specified operating temperature range. Selection Method for Chip Fuses

There are many series of fuses in the electronic component market, among which are patch fuses. This series of fuses is widely used in factories, with few being used by individual users.

According to industry experts, SMD fuses are a relatively high skill level new variety in the small fuse profession. Chip fuses can be divided into chip current fuses and chip self recovery fuses. After one-time fuse maintenance, it needs to be replaced. After self restoring fuse maintenance, it can be self restored and reused after a power outage.

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.

Application of SMD Fuses in Independent Devices

SMD fuse, also known as SMD chip fuse, is a type of SMD packaged fuse that has a wide range of applications due to its small size and chip type. Its application in some independent devices is gradually playing an irreplaceable role.The scope of battery powered equipment has expanded from powerful hand tools for craftsmen to sensors for housing supervision and even medical assistance services. The security of such devices faces enormous challenges. To ensure safe operation of these independent devices, JDTFUSE offers two SMD fuses with low power consumption and high tolerance tripping time.

How to Choose the Rated Voltage and Current of Chip Fuses

How to choose the rated voltage and current of a patch fuse: The rated voltage of a patch fuse depends on the current flowing through it, and is not related to the working voltage of the circuit. From the perspective of safe use, the rated voltage of SMD fuse is proposed, which is the highest working voltage of the circuit when the SMD fuse is in a safe working state. This means that fuses can only be placed in circuits with a working voltage less than or equal to the rated voltage of the fuse. Only in this way can the fuse operate safely and effectively.

How to Design Chip Fuses

In electronic products, chip fuses have two functions: protecting end users from harm and protecting circuits from damage. These functions benefit both device users and manufacturers. Over the past decade, the demand for electronic devices serving information technology, mobile, and consumer applications has sharply increased in the market. With this rapidly growing demand, the risk of unexpected situations in electronic devices has also increased, requiring the use of overcurrent protection devices such as chip fuses to avoid risks such as electrical overload.
