PTC Resettable Fuses

PTC Resettable Fuses are electronic devices which protect circuits from damages caused by electrical overstress, such as an accident or power surge. The 1206L260SLTHYR PTC fuse is a self-resetting protection device designed to protect circuits from overcurrent. It is also known as a PolySwitch device.

1206L260SLTHRY PTC Resettable Fuses

The 1206L260SLTHYR is a surface mountable, single-in-line, two-port, Programmable Transport Controller (PTC) resettable fuse. It provides overcurrent protection for DC-DC converters and AC-DC circuits in cables, computer equipment, consumer devices, hard drives, power strips, and medical equipment. It can handle large surge and pulse currents, but also has a low voltage rating, making it suitable for use in some home automation devices.

Application Field

The 1206L260SLTHYR is used in a variety of applications, such as computer equipment, power supplies, switch mode power supplies, and consumer device power cords. The fuse is suitable for applications which require high inrush currents, such as multiple electronic devices or motors. It is also used in LED lighting applications, as well as in automotive and industrial applications.

Working Principle

The 1206L260SLTHYR consists of an overcurrent sensing element mounted in a slot between two electrodes. When an overcurrent is sensed, the sensing element starts to heat up due to its temperature coefficient. This causes the fusing element to expand, breaking the connection between the two electrodes. This interrupts the electrical flow, resetting the fuse back to its original state and protecting the circuits from further damage.In normal conditions, the fuse has a high breakdown voltage to prevent electrical shorting and fire hazards. It can also withstand high surge currents and has a low trip current to ensure that tripping does not occur at normal currents.

Conclusion

The 1206L260SLTHYR is an effective PTC resettable fuse designed for overcurrent protection of DC-DC converters and AC-DC circuits. It has a high breakdown voltage and can handle large surge and pulse currents. It is suitable for a variety of applications, from computer equipment to automotive and industrial applications. With its fast response time and the ability to self-reset, the 1206L260SLTHYR can protect circuits from the potential damage of overcurrent events.
