PTC (Positive Temperature Coefficient) Resettable Fuses, or Polymeric Positive Temperature Coefficient devices, are electronic devices that are designed to protect electronics from short-circuits and overheating. In the event of an overcurrent event, the PTC Resettable Fuse will open and prevent further flow of electricity through the circuit. Once the overcurrent event is removed, the fuse will automatically reset itself and allow the circuit to work again.

The PTC Resettable Fuse 0ZCB0005FF2E is a resettable fuse with a low value of 0.5 A at 250 V AC, 60 Hz. This type of device can be used in a variety of applications that require reliable protection from short-circuits, overloads, and overheating. Some of these applications include household appliances, automotive, communication systems, office automation, medical, and IT equipment.

The 0ZCB0005FF2E has a working principle based on the PTC Effect. This effect occurs when the temperature of the junction below a certaincurve rises, and the resistance is increased exponentially. The curve is called the PTC curve and is related to the size of the PTC element. When a short-circuit occurs, current flowing through the fuse reaches its critical value and the temperature of the junction rises. As the temperature increases, the resistance of the fuse increases until it blocks the current flowing through it and the fuse opens, protecting the circuit from a short-circuit or an overload situation. When the overcurrent is removed, the fuse returns to its normal state and the circuit is again operational.

The 0ZCB0005FF2E provides excellent current protection in a small form factor and high-temperature operation. It is also designed to provide a reliable Electrical Life of up to thousands of cycles. With its reliable protection and small form factor, the 0ZCB0005FF2E can be used in a wide range of applications where reliable protection from short-circuits and overloads is required.
