PTC resettable fuses feature a solid-state, temperature-responsive Polymer Positive Temperature Coefficient (PPTC) which protects electrical circuits from overcurrent and overvoltage in consumer, automotive, and industrial electronics applications. The YPEK1500T is a streamlined resettable fuse designed to make it easier and safer to design, manufacture, and use electronic systems. Its self-resetting current protection and overload protection properties allow it to provide a range of effective yet lightweight solutions for many applications.

TYEK1500T Application Fields

The YPEK1500T is suitable for applications such as: automotive, consumer electronics, industrial electronics, power supplies, lighting, medical, transportation, and communications. These applications demand reliable safety, yet must often be able to fit into tight spaces, add minimal weight, and fit within specified cost parameters. The YPEK1500T offers all of these features in a single device.

In the automotive industry, YPEK1500T can be used to protect sensitive electronic components and supply systems from excess current such as short circuits or power surges. It also offers a thermal cut-off to protect against overtemperature situations or unexpected component or system failures. In the consumer electronics space, it can provide fail-operational current protection in laptop computers, cell phones, tablets, and other electronic devices

The YPEK1500T can also be used in the industrial and power supply applications. Here, it can provide circuit protection in devices such as relays, containment systems, power supplies, solenoid valves, and robotic systems. In the medical field, it can be employed to protect medical equipment from electrical shock or malfunction. And in the communications industry, the YPEK1500T can be used to protect modems, servers, and antennae.

YPEK1500T Working Principle

The YPEK1500T features a unique Polymer Positive Temperature Coefficient (PPTC) technology which allows it to provide current protection up to 1500 amps and overload protection up to 250v. This solid-state device works by sensing heat caused by an overload in the electrical circuit. When the current reaches an unsafe level, the PTC material quickly switches from its low-resistance (ON) state to a high-resistance (OFF) state, thus ceasing current flow.

In the event of an overload, the PPTC device will immediately increase its resistance, thereby cutting off current flow in the circuit. Once the current and/or voltage levels return to a safe level, the PPTC device will reset itself and resume the low-resistance, ON state. This self-resetting property is beneficial in that it allows previous circuit conditions to be restored without having to manually open and reset fuses or circuit breakers.

The YPEK1500T also features a built-in thermal cut-off protection which will automatically cut off power in the event of an overtemperature situation or unexpected component or system failure. This feature ensures a high level of safety and can prevent further damage to the circuit or the surrounding environment.

Conclusion

The YPEK1500T is a streamlined resettable fuse that has been designed to provide fast and reliable over-current and over-voltage protection in a wide range of applications. Its self-resetting current protection and overload protection properties ensure a high degree of safety, while its small size and low weight make it an ideal solution for many tight-space applications. This makes the YPEK1500T a great choice for designers, manufacturers, and users of electronic systems who require safe, reliable protection in a relatively small package.
