PTC Resettable Fuses are used to protect devices, circuits, and systems against overcurrent and overvoltage problems. This is accomplished by providing an automatic electrical disconnect when a pre-determined level of current or voltage is exceeded.

The B59673A0100B110 is a PTC Resettable Fuse, specifically designed to protect electronic circuits against overcurrent faults from transients and short circuits. This type of fuse is based on the resistive heating principle and works in three phases. Firstly, the fuse senses the current moving through it and the temperature inside the fuse starts to increase. Secondly, when the temperature inside the fuse reaches the actuation temperature (at a maximum current), the fuse trips and interrupt the current flow. Finally, the fuse cools down and the current can flow again.

The wide range of applications of these fuses is due to their unique current limitation characteristic. They are ideal for all types of consumer electronics, automotive electronics, telecommunications and industrial applications. With multiple electrical pathways, these devices are also ideal for providing short-circuit protection with failure detection, as well as current-limiting and fault-tolerant protection.

The B59673A0100B110 features several important characteristics that make it suitable for multiple applications. It has a rated current of 100mA, a rated voltage of 16V and a typical trip time of 50msec at 125% of the rated current. Additionally, this fuse exhibits an excellent reset temperature characteristic and fast resetting capability. This makes it suitable for overcurrent applications that require a continuous current monitoring.

The B59673A0100B110 can be used in a number of different applications. These include overcurrent protection on AC and DC power supplies, overvoltage protection on DC power supplies and battery-charging circuits, overvoltage and overcurrent protection of IGBTs, and overcurrent protection of microprocessors and ASICs. Additionally, this fuse can be used for biomedical, electric motors, and temperature sensors.

The importance of reliable overcurrent protection in electronic systems cannot be underestimated. PTC Resettable Fuses such as the B59673A0100B110 provide excellent protection against both overcurrent and overvoltage faults. Utilizing the resistive heating principle, these devices are able to quickly and accurately trip in the event of an overcurrent and then reset when the fault condition has been eliminated.
