PTC Resettable Fuses, also known as polymeric positive temperature coefficient (PPTC) fuses, are commonly used to protect circuits from thermal and electrical overloads. The PTGL12AS1R2K3B51A0 are one such type of resettable fuse. It is used in high-current applications such as automotive, cellular device, and printer sectors, among others.

Application Field of PTGL12AS1R2K3B51A0

The PTGL12AS1R2K3B51A0 PTC Resettable Fuse can be used for a variety of applications. It is often employed in automotive applications, such as headlights, taillights, turn signals, and heated mirrors. It is also useful in other industrial applications such as motor control circuits, displays, power supplies, and more. The fuse is especially helpful in portable electronic devices like cellular phones, portable music players, e-readers, and tablets, as it helps protect against short-circuits.

The fuses are also used in medical equipment, consumer appliances, computers, audio playback equipment, and other industries. They can provide protection against thermal overloads and regular electrical overloads, which could cause fire, failure, or other damage. High-end automobile models may even require the use of the PTGL12AS1R2K3B51A0 fuse.

Working Principle of PTGL12AS1R2K3B51A0

When the current passes through the PTC Resettable Fuse, electrical resistance is generated due to the internal heating. This resistance increases with current levels, and the heat generated reduces the user’s ability to pass electrical current in the circuit, resulting in an automatic shutdown of the circuit. Upon cooling, the resistance decreases back to its original level, enabling user to resume their work.

In more technical terms, when the current level rises above the rated value, the PTC Resettable Fuse reaches its Response Temperature (TR). At this temperature, hydrogen ions are formed inside the fuse\'s polymer. Consequently, the conductivity of the material is reduced, resulting in an increase in the fuse\'s internal resistance, which causes it to turn off. Due to this decrease in the device\'s temperature, the hydrogen ions recombine and the resistance returns to its lower levels, allowing the user to continue.

In addition to the thermal overload protection, the PTGL12AS1R2K3B51A0 PTC Resettable Fuse also provides a good level of electrical protection. It features a maximum hold current of 2A and maximum opening current of 5.8A. This allows the fuse to protect against sudden current increases, offering reliable protection against potential short-circuits.

In conclusion, the PTGL12AS1R2K3B51A0 PTC Resettable Fuse is a reliable and efficient way to protect circuits against thermal and electrical overloads. It is used in a wide range of industries, from automotive to medical applications, due to its high current carrying capacity and accurate response temperature. Thanks to its resettability, it allows users to resume their work with minimal downtime.
