PTC Resettable Fuses are safety devices designed to protect sensitive equipment from over-voltage, over-current, shorts, and other potential problems. The PTC Resettable Fuses consist of two basic types, namely, Active and Passive. The Active PTC Resettable Fuses use a Transient Voltage Suppressor and a Shunt Resistor to provide over-current protection. The Passive PTC Resettable Fuses use a PTC element and a Shunt Resistor to provide over-current protection. The most commonly used PTC Resettable Fuses are the standard PTC-R, also known as the PTR03V0135-TR1 series.

The PTR03V0135-TR1 series PTC Resettable Fuses are designed for a wide range of AC and DC applications. It is suitable for applications with an operating voltage of up to 3V and a current rating up to 35A. It has a holding current of 0.15A and a release current of 2A. The PTR03V0135-TR1 series is rated to operate from -40 to +85°C. It is constructed from a ceramic body material with tin plated copper-lead contacts for a reliable electrical connection.

The working principle of the PTR03V0135-TR1 series PTC Resettable Fuses is quite simple. When the current exceeds the maximum rated current, the ceramic body of the fuse heats up quickly, causing its internal resistance to increase dramatically. This increase in the internal resistance limits the current, protecting the connected equipment from the high current. When the current falls below the maximum rated current, the ceramic body of the fuse cools down and its internal resistance returns to normal, allowing current to flow again.

The major application fields of the PTR03V0135-TR1 series PTC Resettable Fuses are in the industrial, medical, automotive, and consumer electronics industries. It is used in a wide variety of electronic devices and appliances, such as computers, printers, photocopiers, medical equipment, car audio systems, telecommunication devices, marine equipment, and audio/video equipment. It is also used in battery charging and protection circuits and solar panel circuits.

The PTR03V0135-TR1 series PTC Resettable Fuses provide an excellent combination of performance and protection in a wide range of applications. These fuses are available in multiple packages and configurations, making them suitable for small to medium-sized power supply designs. They provide reliable and cost-effective over-current protection for a variety of applications and are an ideal choice for protecting electronic equipment.
