PTC Resettable Fuses, commonly known as polyfuse, are made up of a ceramic body with electrodes, usually two for higher current ratings, and a polymer material located in between the electrodes. The polymer has a high resistance at room temperature, which results in a low current flow. When a current goes through the fuse and exceeds the preset current limit, the resistance of the polymer changes abruptly and the fuse reacts. This reaction causes the current flow to be restricted and the high temperature generated will heat up the polymer causing a change in its structure as well as its resistance. As the temperature reduces, the resistance of the polymer also reverts to its original value.

The B59870C0120A070 is one example of a PTC Resettable Fuse and has applications in communications electronics, networking products such as switchgear and power supplies. Furthermore, it works by protecting electronic components against over-voltage, over-current or short-circuit events. The component can also be used in automotive and industrial environments, and additional applications include electric vehicles, LED or battery packs, and in medical and consumer products.

The fuse is available with a current rating of ½ A to 24 A, with a voltage rating of 250 V or 400 V. Additionally, it is also UL certified and is designed with a response time of less than 5ns to an over-current of 1A, 15A and 20A. The high current capacity and thermal dissipation behaviour of the B59870C0120A070 enable a low thermal impedance and a maximum temperature rise of 40°C.

When the over-current or short circuit event occurs, the PTC fuse heats up, arising a thermal current which raises the temperature of the fuse element. After the surge is cleared and the thermal current is over, the fuse reverts to its original state allowing for the current flow to normalise.

The B59870C0120A070 PTC Resettable Fuse that complies with JEDEC standard is suitable for flow, wave and selective soldering processes and can be reflowed in the form of a standard surface mount component procedure. It requires no external circuitry and is easily capable of measuring a wide range of loads, whatever the environmental temperature. Furthermore, it requires no external resistors or other components to control the reset voltage; it is totally self-regulating.

The PTC resettable fuse offers an excellent protection solution for a wide variety of circuits. It also provides an efficient thermal protection, reducing the maintenance cost and ensuring a long lifetime for the circuit. It also complies with even the harshest environmental standards and works within a wide temperature range.

For highly reliable over-current protection, the B59870C0120A070 PTC Resettable Fuse is a perfect candidate and is widely used in various commercial and industrial applications. The component consists of a ceramic body with electrodes, a polymer material located in between the electrodes, and is designed with a response time of less than 5ns to an over-current of 1A, 15A and 20A. Furthermore, it has a current rating of ½ A to 24 A and a voltage rating of 250 V or 400 V. The PTC resettable fuse ensures a high current capacity, thermal dissipation, and offers a low thermal impedance with a maximum temperature rise of 40°C.
