What is a RXEF135K-AP PTC Resettable Fuses?

PTC resettable fuses are special types of fuses which have the capability to reset themselves when a slight excess of voltage is applied. RXEF135K-AP is one of the most popular PTC resettable fuses available on the market. It is characterized by a solid-state polymer body and employs a low insert resistive melting element in order to protect electrical circuit against excess voltage.

Application

RXEF135K-AP can be used in various different applications such home electronics, industrial electronics, automobiles, and power supplies. As a overload protection fuse, this PTC resettable fuse serves to prevent excessive voltage from causing damage to your electrical components. In home electronics, it can be used in applications such as hair dryers, microwaves, and laptop chargers. In industrial electronics, RXEF135K-AP can be used in protection of AC/DC drives, medical instruments, and electric motors. It is also popular in automobiles as a safety fuse for protecting the engine and other electronic systems from overheating. The most popular application for RXEF135K-AP is in power supplies, where it helps in protecting the computer components from high surge voltage.

Working Principle

The working principle of the RXEF135K-AP PTC resettable fuses is pretty simple. Under normal working conditions, the fuse is connected to an electrical circuit in series. When a slight excess of voltage is applied to the circuit, the temperature within the fuse rises rapidly. This causes the fuse to release its stored energy and reset itself automatically. The fuse will stay in a reset state until the overload condition is resolved. Once the power is resumed, the fuse will automatically return to its normal operating state.

RXEF135K-AP resettable fuses offer many benefits in terms of power supply protection. They are resistant to corrosion, have a low thermal resistance, and can be placed in different orientation without affecting the circuit’s operation. This resettable fuse is also highly reliable and will reset automatically without any human intervention. In addition, this type of fuse will usually react faster than other standard fuses, making it ideal for circuit designs that require fast response times.

Although RXEF135K-AP PTC resettable fuses offer many advantages, they may not be suitable for all applications. For instance, they require a certain level of voltage for resetting, which can be difficult to meet in some conditions. Furthermore, PTC resettable fuses are typically more expensive than standard fuses, which can be a disadvantage. Therefore, it is important to weigh the pros and cons of using a RXEF135K-AP before deciding whether it is the best option for your circuit.

In conclusion, the RXEF135K-AP PTC fuse is an effective means of protecting your circuits from overvoltage. Its automatic resetting feature allows for reliable protection without requiring any human intervention. However, it is important to carefully consider the application and determine whether this type of fuse is suitable for the circuit before making a purchase.
