PTC Resettable Fuses Application Field and Working Principle - RLD60P065XFF

PTC (Positive Temperature Coefficient) Resettable Fuses are self-regulating heating elements which are placed in electric circuits to protect them from overloads. The RLD60P065XFF model is one of the most widely used resettable fuse models and has a wide range of applications.

A PTC resettable fuse consists of two parts – a thermistor and a resistor. The thermistor has a positive temperature coefficient, which means that when temperature increases, the resistance increases proportionally. This is why PTC resettable fuses are also referred to as self-regulating fuses. The resistor is used to control the current in the circuit. When the current reaches a certain level, the thermistor begins to heat up. The heat generated by the thermistor causes the resistance to rise, limiting the current and protecting the circuit.

An RLD60P065XFF PTC resettable fuse is rated for 60 volts and has a maximum continuous current rating of 0.65 A. This model is designed to protect sensitive components and circuits from overloads. It has a fast response time and can quickly detect any surge or abnormal current. It also has high thermal and electrical stability. The RLD60P065XFF is commonly used in power supply units, lighting systems, automotive electronics, and industrial control systems.

The RLD60P065XFF PTC resettable fuse works by limiting the current in the circuit. When the current reaches the preset level, the thermistor in the fuse begins to heat up. The temperature rise causes the resistance of the thermistor to increase, limiting the current and protecting the circuit. Once the current is limited, the thermistor begins to cool, the resistance decreases, and the circuit is restored to normal operation. Also, unlike a normal fuse, a PTC resettable fuse does not have to be replaced after each overload. All it needs is to be reset manually or electronically.

The RLD60P065XFF PTC resettable fuse is an effective and reliable solution for protecting circuits from overloads and surges. It is well-suited for applications such as power supplies, lighting systems, automotive electronics, and industrial control systems. Not only does it provide protection for sensitive components, but it also reduces the risk of downtime due to regular maintenance.
