PTC Resettable Fuses: PTCCL13H321HTE applications and working principles.

PTC Resettable Fuses are widely used in the automotive, medical, and consumer electronics industries due to their ability to automatically shut off power to protect sensitive components from overload. The PTCCL13H321HTE is an especially popular model, thanks to its convenience, safety and reliable performance. In this guide, we\'ll look at the application field and working principle of this part number, to give you a better understanding of its capabilities.

Applications

The PTCCL13H321HTE is capable of handling up to 3.2A of current at up to 300VAC, making it suitable for a range of applications. It can be used in high-power consumer electronics such as laptops, desktop computers, tablets and other electronic devices. It is also ideal for medical electronics where safe electrical currents are needed for medical equipment. Furthermore, the device can also be used in automotive applications such as power windows, seat controls, airbags and alarm systems.

Working Principle

The device is designed to provide over-current and over-temperature protection, and works by responding to excessive temperatures or current levels. The integrated PTC element carries the full load current and can be reset after an over-current or over-temperature event. The PTC element is self-heating due to its own self-induced current, and when the temperature reaches a critical level it will cause an increase of the PTC resistance that reduces the current. Once the temperature has cooled the device can be reset by pressing the reset pin.

The integrated PTC element of the PTCCL13H321HTE uses a single-piece design, which eliminates the need for assembly and reduces cost, allowing for greater thermal performance with reduced size. The PTC element also features a temperature rating of 105 °C, allowing for safe use in a variety of applications where higher temperatures are expected.

The device also features a two-piece holder design, which ensures secure installation in tight spaces. This holder design provides a secondary level of protection from dust and foreign objects, and allows for easily replacing of the device if needed.

In addition, the device also features a UL 94V-0 flammability rating for added safety assurance, making it suitable for use in commercial electronic installations.

To sum up, the PTCCL13H321HTE is a popular part number because of its convenience, safety and reliable performance. It is capable of handling up to 3.2A of current at up to 300VAC, and can be used in high-power consumer electronics, medical electronics and automotive applications. Furthermore, its integrated PTC element, two-piece holder design and UL 94V-0 flammability rating ensure reliable protection against over-current and over-temperature conditions.
