PTC Resettable Fuses are protection devices which are designed to provide fail-safe protection to electronic circuits against accidental overload and short circuit faults. The 1206L005/60WR type of PTC Resettable Fuse belongs to the popular series of 1206 size resettable fuses from the well-known manufacturer. It is equipped with locking type plug-in terminals for connection to the circuit. The 1206L005/60WR PTC Resettable Fuse has an electrically rated current of 0.5A which can be used for drop-in replacement of over-current protection devices in various electronic circuit applications.

The 1206L005/60WR PTC Resettable Fuse offers a number of advantages such as its low profile design, fast acting current limiting protection, low power dissipation, low temperature coefficient, superior thermal performance, superior flame retardant characteristics, and low leakage current. It also provides freedom from nuisance tripping, low temperature coefficient of about ±2.3%, and automatic resetting without manual intervention. The characteristics of the 1206L005/60WR PTC Resettable Fuse make it suitable for use in a wide variety of applications such as lighting fixtures, LED sign and lighting, home appliances, portable electronics, automotive electronics, consumer electronics, power supplies, and instrumentation circuits.

The working principle of the 1206L005/60WR PTC Resettable Fuse lies in the fact that the fuse element consists of a resistive polymer with a high electric resistance when it is cold. When the surrounding temperature increases due to the over-current fault, the resistance of the polymer decreases, allowing the current to pass through the element. The current then decreases until the thermal resistance of the element increases again, blocking the current and protecting the electronic circuit. Once the temperature is below a certain predefined value, the fuse element will reset itself and the current will be allowed to flow through the element again.

The advantages of using the 1206L005/60WR PTC Resettable Fuse include its compact size, high cycle life, low cost, and the fact that it does not require manual intervention for resetting. It is also more reliable than the other types of protection devices such as circuit breakers and fuses. Additionally, it offers faster over-current protection than other conventional devices and it has wide operating temperature range.

In conclusion, the 1206L005/60WR PTC Resettable Fuse is a reliable and cost-effective protection device designed for a variety of applications. Its working principle is based on the fact that the resistance of the element changes when it is heated up due to the over-current fault. Its numerous advantages make it suitable for use in a wide range of electronic circuits. It is also offers fast-acting protection, freedom from nuisance tripping, and automatic resetting without manual intervention.
