PTC Resettable Fuses technology has been developed for the protection of electronic circuits and components from overload, short-circuit and reversed-polarity faults. The PTC Resettable Fuses offer this protection in the form of a polymeric thermistor, typically made of poly-phenylene sulfide (PPS).

The PTR030V0400-TR1 is a PTC Resettable Fuse, which is designed to protect against an overcurrent condition. It is ideal for applications such as power supplies, battery chargers, AC adapters and portable electronic devices. The PTR030V0400-TR1 is packaged in TO-220 shape with two pin (black and red) that provides a wide range of DC and AC reset characteristics.

The working principle of the PTC Resettable Fuse relies on the unique characteristics of the PPS thermistor material. It is temperature sensitive and exhibits a positive temperature coefficient (PTC) over a certain temperature range, which allows it to increase its resistance in the presence of an overcurrent condition. In normal operating conditions, the resistance of the fuse is low, thus allowing proper current flow. However, when an overcurrent is present, the temperature of the fuse increases, resulting in the increase of its resistance. The increase of its resistance causes a drop of the current in the protected circuit, thus providing the desired protection.

Once the condition that triggered the overcurrent protection is removed, the PTC thermistor will cool down and its resistance will decrease again, thus restoring normal operation. This is a unique characteristic of the PTC Resettable Fuse, as it allows the user to easily reset and reuse the fuse again.

In addition, the PTC Resettable Fuse provides superior overcurrent protection compared to traditional fuses, as it can be reset multiple times, thus eliminating the need to replace fuses frequently. This reduces cost and maintenance of the device.

The PTR030V0400-TR1 is currently used in a wide range of applications such as power supplies, battery chargers, AC adapters, portable electronic devices and embedded systems. It provides reliable and effective overcurrent protection in these applications, thus ensuring maximum safety and reliability of the device.

The PTR030V0400-TR1 is a reliable and cost-effective solution for providing effective overcurrent protection in a wide range of applications. It provides superior protection than traditional fuses and can be easily reset for reuse multiple times, thus greatly reducing cost and maintenance of the devices.
