PTC Resettable Fuses are self-resetting devices that provide short circuit and overcurrent protection for sensitive electronics. They provide surge protection for equipment, creating a virtually maintenance-free environment. PTC Resettable Fuses provide flexibility in their application fields, enabling engineers to select the optimal Fuse for their specific needs. Quite often, depending on the application, components may require different Fuses, featuring different features such as current ratings, fuse time delay, response time, mountings, and trip characteristics.

The PTR016V0120-TR1 is a radial leaded PTC Resettable Fuse designed to provide overcurrent protection and circuit interruption for a wide range of applications. It is rated at 16V, 1.2A nominal, and has a maximum hold current of 0.2A. Its features include a self-resetting mechanism, a fast response time of less than 1ms, and low thermal impedance for improved heat dissipation. The PTR016V0120-TR1 has an operating temperature range of -40°C to +85°C.

The PTR016V0120-TR1 is ideal for applications where reliable and fast overcurrent protection is required. It is suitable for use in televisions and other audio-visual equipment, as well as appliances and chargers. It is also suitable for using in DC/DC converters and other DC power systems, providing reliable short-circuit and overcurrent protection. The PTR016V0120-TR1 is also suitable for use in battery packs and laptop computers, additionally protecting them from accidental short-circuits.

The working principle of PTR016V0120-TR1 is centered around the thermal-magnetic effect, which occurs when an electrical current is applied to the device. This causes the internal fuse element (which is usually a wire) to heat up, eventually triggering a reaction where the fuse wire is disconnected from the circuit, temporarily or permanently. This “tripping” of the fuse effectively breaks the circuit, and prevents further current from passing through it. The PTR016V0120-TR1 has a thermal-magnetic multi-trip mechanism, which allows it to outperform traditional fuses in overcurrent protection applications.

When the overload current becomes greater than the operating current, the temperature of the fuse element rises quickly. As the temperature approaches the thermal trip level, a magnetic field is created, which causes the fuse to trip (open) and break the circuit. Once the trip has occurred, the magnetic current stops, and the thermal current starts to decay until the temperature drops to a safe level. At this point, the circuit is re-established and current begins to flow again. This provides the user with a fast response time which can greatly reduce the risk of damage to the device being protected.

The PTR016V0120-TR1 is a reliable solution for a wide range of applications. Its features and capabilities make it suitable for providing overcurrent protection in many different environments, making it an ideal solution for protecting sensitive electronic components.
