0TOO.300Z Application Field and Working Principle

0TOO.300Z is an ultra-small fuse module developed by Shenzhen Portable Power Technology Co., Ltd. It is particularly suitable for the protection of miniaturized printed circuit boards. Since its appearance in the power module market, it has gradually attracted the attention of many users with the advantages of high current, fast response and precise protection.

1. Application Field

The 0TOO.300Z fuse is used primarily in automotive electronics, wind turbine electronic protection, solar smart grid equipment, medical protection, industrial control, battery protection, small consumer electronics, computer motherboards, automotive brake electronic control, DC UPS power supply protection , automotive fuel injection electronic control system, medical device protection and so on.

2. Working Principle

The 0TOO.300Z ultra-small fuse module is a current-sensing circuit breaker. It is a circuit breaker consisting of a silver palladium alloy contacts. According to the current, the temperature of the two contacts rises quickly. When the current is too high, the heat is concentrated on a very small area and causes the metal contacts to melt. When the fuse melts, the current is cut off and the circuit is broken. This kind of circuit breakers usually have higher rated currents than other circuit breakers. During the operation, heat energy concentrated on the contact pair will break down quickly. The output current is very small after the fuse is broken, so as to effectively protect the circuit. At the same time, the material utilized in 0TOO.300Z is heattable-resistant and flame resistant, which make it have good safety performance.

3. Advantages of 0TOO.300Z

The advantages of 0TOO.300Z ultra-small fuse modules include low thermal resistance, low temperature drift, and small size. It has current up to 300A and operating frequency up to 50A. The design of simply control points deposition also ensures the accuracy of protection and fast response to large inrush current.

4.Conclusion

In this article, we introduced the application field and working principle of 0TOO.300Z ultra-small fuse module. It is mainly used for the protection of miniaturized printed circuit boards. During operation, the current-sensing circuit breaker melts the metal contacts when the current is too high, thereby ensuring the efficiency and accuracy of protection. The use of this module can protect the circuit more effectively.
