PTC Resettable Fuses: PTR030V0135-TR Application Field and Working Principle

PTC resettable fuses are a type of overcurrent protection device that can be reset without having to physically replace the device after tripping. This makes them ideal for applications that require multiple trips, such as automotive, consumer electronics and even medical devices. The PTR030V0135-TR is a surface-mist soldered miniature PTC resettable fuse designed for use in portable electronic devices, such as mobile phones, tablets, and laptops. In this article, we will discuss the application field and working principle of the PTR030V0135-TR PTC resettable fuse.

Applications

As mentioned earlier, the PTR030V0135-TR is primarily used in portable electronic devices, such as mobile phones, tablets, and laptops. It is also used in automotive, consumer electronics, and medical applications. The device is designed for surface-mount soldering, and has a low profile package that allows it to fit in tight spaces. It has a high voltage rating of 35V, making it suitable for a wide range of applications.

Working Principle

The working principle of the PTR030V0135-TR is fairly simple. When the current of an electronic device exceeds the rated value of the fuse, the resistance of the fuse increases and the voltage across its terminals drops. This reduces the flow of the current and the device is protected from potential damage. To reset the fuse, one simply needs to reduce the current and allow the voltage across its terminals to return to its normal value.

Advantages

One of the main advantages of the PTR030V0135-TR is its ability to be reset without having to physically replace the device. This makes it ideal for applications where multiple trips are required, such as automotive, consumer electronics, and medical devices. It also has a wide voltage rating, making it suitable for a variety of applications. Finally, its low profile makes it ideal for use in tight spaces.

Disadvantages

One of the main disadvantages of the PTR030V0135-TR is its limited current rating. At only 1.35A, it is not suitable for applications that require higher current ratings. Additionally, its limited temperature range of -55C to +125C means that it is not suitable for applications that require higher temperatures.

Conclusion

The PTR030V0135-TR is a surface-mist soldered miniature PTC resettable fuse designed for use in portable electronic devices. It has a wide voltage rating, making it suitable for a variety of applications. Its ability to be reset without having to physically replace the device makes it ideal for applications that require multiple trips, such as automotive, consumer electronics, and medical devices. However, it has a limited current rating and temperature range, so it is not suitable for applications that require higher ratings.
