PTC Resettable Fuses

A PTC resettable fuse, also known as a polyfuse, is a type of fuse that can be reset after tripping due to overload. It is composed of a polymeric positive temperature coefficient (PPTC) element and two or more metal strips which form the terminals. The PPTC element acts as a switch with a metal strip connected at one end and the other end connected to a lead. When the current passes through this element, it causes the element to heat up and expand, pushing open the contact and thus interrupting the circuit. The circuit can be reset simply by allowing the element to cool down and reset the contact, thus reestablishing the circuit.

The B59711A0120A062 PTC resettable fuse is designed as a current limiting device. It has a rated voltage of 16 V and rated current of 2.2 A. The fuse is designed for protection against over-current and short-circuit faults in automotive applications such as power controllers, motor controllers, and sensors. It also provides protection from transient over-voltage spikes and reverse currents.

The B59711A0120A062 fuse has two primary working principles. Firstly, the fuse has a thermal cut-off mechanism which limits the amount of current passing through the fuse, and once the set current is achieved, it trips the power automatically. This ensures the device is protected in case of an over-current situation. Secondly, the fuse also acts as a resettable element, which reset itself after the current is returned to normal and the thermal cut-off mechanism is reset.

The B59711A0120A062 resettable fuse is suitable for use in a variety of automotive applications such as automotive lighting, control systems, audio systems, engine control, and emergency lighting systems. It is particularly suitable for applications where constant power supplies are necessary and a power failure cannot be tolerated. In these applications, the resettable fuse provides a reliable and cost-effective solution for protecting against any unforeseen overloads.

The B59711A0120A062 PTC resettable fuse is a reliable, cost-effective, and user-friendly solution for automotive applications. Its thermal cut-off mechanism ensures current-limiting protection, and the resettable feature makes it an ideal choice for auto systems where power failure cannot be tolerated.
