PTC (Positive Temperature Coefficient) Resettable Fuses are increasingly used in various electrical and electronic applications due to their robustness, cost effectiveness, and reliability in the protection of circuits and components from short-circuits and overload currents. The 0ZCH0075AF2E is one such device, used to protect consumer electronics, industrial equipment, and automotive circuitry from thermal and short circuit events.

The 0ZCH0075AF2E is a surface-mount current-limiting device with an over-temperature protection (OTP) feature. It is designed to protect circuits from surges, short circuits, and thermal overloads. The OTP feature is especially important for applications such as hot-swapping, where sudden changes in temperature due to external forces can cause catastrophic damage if not properly controlled.

The 0ZCH0075AF2E is an ideal choice for these kinds of applications, due to its thermal and dynamic stability. This device automatically resets after a thermal or over-current event, making it incredibly easy to use and maintain.

The 0ZCH0075AF2E is designed to open its internal contact in the presence of an over-current condition. When an overload condition is detected, the device activates a THER-MICRONIC device to break the connection within the device, thus interrupting the flow of current. The THER-MICRONIC device will remain disengaged until the overload current is reduced to a safe level, at which point the thermostat will reset and the circuit is ready to start again.

The 0ZCH0075AF2E is capable of operating in temperatures of -25° C to +105° C. It features a local indication LED; this LED indicates when an over-current or thermal overload has occurred, and when the device has reset itself. It has an operating current of 2.5A to 25A and a minimum trip current of 5A. It also has a rated energy of 1.3 Joules which allows the device to absorb incoming surges and protect the system from harm.

The 0ZCH0075AF2E also features self-resetting functionality, a robust pressure contact, and a 2-piece design for easy installation. Combined with its lengthy life and great reliability, the 0ZCH0075AF2E is an effective solution for thermal and short circuit protection.
