PTC Resettable Fuses (PPTC) are a type of over-current protection device. They are often used in automotive, medical, and other industrial applications. The fuse is designed to protect circuits from current spikes or short circuits. When normal levels of current are exceeded, the fuse will open, interrupting the current flow, and thus protecting the circuit.

NANOSMDH075F-02 is a PTC resettable fuse with a 2.0A operating current and a 275VAC operating voltage. It is designed to provide excellent over-current protection in multiple applications. It is available in three different sizes – 0805, 1206 and 2512 – and is designed for use in the exacting applications found in automotive, medical and industrial systems. The fuse has excellent temperature performance, with an operating temperature range of -55°C to +125°C, and excellent protection levels.

The NANOSMDH075F-02 is designed to provide a reliable and consistent level of circuit protection. It has a fast response time of 390ms for overcurrent, and a response time of less than 1 second for overtemperature. This ensures that when current spikes occur, the fuse will trigger faster than a conventional Overcurrent Protection (OCP) device, providing superior protection. The fuse will then reset itself once the overcurrent protection is no longer required.

The NANOSMDH075F-02 works on the principle of thermally activated positive temperature coefficient (PTC). When the predetermined current rating is exceeded, the PTC element raises its resistance which causes the current through the device to drop significantly. This reduces the power dissipated in the fuse and trips the fuse in a few milliseconds, thereby protecting the circuit. The PTC element remains in a high-resistance state until the power is depleted, at which point it cools and the resistance returns to its original low level, thus resetting the fuse.

The NANOSMDH075F-02 can be used in a variety of applications, such as AC and DC line fusing, power distribution, motor control, and lighting control. It is ideal for applications where size and space are at a premium. It is also suitable for automotive and industrial applications that require reliable and consistent circuit protection. In addition, its high surge capability, reliable reset, and wide temperature range make it suitable for a range of different applications.

In summary, the NANOSMDH075F-02 is a PTC resettable fuse designed for use in a variety of applications. It has a fast response time and excellent temperature performance, making it suitable for the most demanding applications. It is a reliable and consistent over-current protection device that can provide superior circuit protection when needed.
