PTC Resettable Fuses, like the PTR060V0020-TR, are designed to provide reliable circuit protection over a wide range of current and environmental conditions. They are an important tool for ensuring the reliable operation of circuits and preventing potentially dangerous or expensive failures. The application field and working principle of the PTR060V0020-TR are discussed in the following sections.

Application Field

The PTR060V0020-TR is a resettable fuse designed to protect circuits from overcurrent. It can be used in a wide variety of applications, from basic power supply protection to industrial machine control. In addition, the device has an ultra-low hold current of only 12mA and offers short-circuit protection. This makes it well suited for application in areas where power needs to be quickly and efficiently managed, such as automotive and consumer electronics.

The fuse is also well suited for protection on board level, as it is designed to be placed directly on board or as part of an integrated circuit without any additional components. This makes the PTR060V0020-TR an ideal choice for circuit protection in mobile devices and other small spaces. The fuse also features a wide operating temperature range between -55°C and 150°C, making it suitable for a wide range of applications.

Working Principle

The PTR060V0020-TR is a Polymer Positive Temperature Coefficient (PTC) Resettable Fuse, which functions based on the principle of thermistors. These devices are specifically designed to heat up as the current through them increases. As the temperature rises, the resistance of the fuse increases, resulting in a decreased current and eventually cutoff. This action protects both the device and the power supply from overloads.

When the overcurrent situation ceases, the fuse cools down and its resistance lowers to its original state. This is known as resetting the fuse, as it now functions as if it were never activated in the first place. This is why these types of fuses are often referred to as “self-resetting”.

The PTR060V0020-TR features a comprehensive protection system, and has many advantages over traditional fuses. One of the primary advantages is that these fuses are non-destructive, allowing them to be reset multiple times without having to replace the device itself. This makes them a cost-effective and reliable solution for circuit protection. They also offer higher current ratings than traditional fuses.

Conclusion

The PTR060V0020-TR is a resettable fuse designed to provide reliable circuit protection in a variety of applications. It is an ideal solution for protecting board level components, as it can be placed directly on board or as part of an integrated circuit without the need for additional components. The device features an ultra-low hold current of only 12mA and offers short-circuit protection. It also has a wide operating temperature range of -55°C and 150°C. Furthermore, the device operates on the principle of thermistors, providing reliable and cost-effective protection against overloads and other circuit damage.
