PTC resettable fuses, or polymeric positive temperature coefficients, are type of devices used to protect electronic and electrical circuits from damage due to overcurrent. This type of fuse has the capacity to automatically "reset" itself after the fault current has been removed, providing protection for connected circuits from further damage. An 1812L 200DR application field is a unique application field utilizing such a PTC resettable fuse.

The 1812L 200DR application field is ideal for protection of low-voltage equipment from inrush current damage, such as medical and communications equipment. This application field offers protection from alternating current overload, and it is suitable to be used in a range of industries, from industrial control systems, to computer power supplies, to remote controls.

The way PTC components work is by having an accurate temperature coefficient, which increases with the amount of current applied to the device. When the current reaches the preset threshold of the device, the device will open, and thereby stopping the current from reaching the circuit. When the current is restored, the device will reset, allowing the current to reach the circuit and the circuit to be operational again.

In the case of an 1812L 200DR application field, the device utilizes an internal resistor to reduce the peak current. The temperature of the device and the resistance accordingly increases with the increasing of current. When the preset limit is reached, the temperature of the resistor will increase and the resistance of the device will increase as well, thus stopping the flow of current to the device. Once the current is removed, the device will cool down and .the resistance of the device will decrease, allowing it to reset and allowing the current to flow through the device again.

The 1812L 200DR application field also utilizes a special design of fuse holder which provides a better path for current to travel and ensures optimal contact between the device and the circuit components. The device also has a low resistance design which provides highly efficient operation and a long life span.

Due to their unique resetting abilities, PTC resettable fuses are becoming more and more popular in various industries. The 1812L 200DR application field is an example of its use, offering protection from inrush current damage and high temperatures. Such a device is ideal for applications such as medical equipment and communications equipment, as its unique resetting abilities provide a higher level of protection than traditional fuses.
