PTC Resettable Fuses, also known as polyfuses, are self-resetting circuit protection devices that are being increasingly used in many commercial and automotive devices. They are designed to protect electronic circuits from current overloads and short circuits. In this article, we shall look at the application fields and working principle of the 1812L200/16DR Resettable Fuse.

Resettable fuses are quickly becoming an important part of the safety and system protection of many electronic systems. In comparison to traditional fuses, they possess some unique properties that make it valuable for many modern electronic systems. Resettable fuses are non-destructive, meaning that they need not be replaced every time the load exceeds the fuse\'s rating, and the fuse can be used multiple times. This is also referred to as “trips”. Additionally, these fuses are also compact in size and are less expensive than traditional fuses. Finally, they are also extremely temperature tolerant and can operate at extremely wide temperature ranges.

The 1812L200/16DR Resettable Fuse has a voltage rating of 200V AC/DC and a current rating of 16A. It supports an operating temperature range of -55°C to 125°C, and has a time-to-trip characteristic response of 2.3 seconds. It is also UL, ENEC, and CCC rated.

The application fields of the 1812L200/16DR fuse include portable electronic devices, home appliances, windows and phone chargers, automotive devices, backup power supplies, and power supplies that use heavy loads. It is also used extensively in industrial, military, aerospace, and medical equipment.

The working principle of this Resettable Fuse is simple. When exposed to currents greater than its rated current, the fuse trips and the current is cut off. However, unlike traditional fuses which must be replaced, the 1812L200/16DR Resettable Fuse can be reset by simply disconnecting and re-connecting it. When the overload current is cleared, the fuse automatically resets and the circuit resumes its normal operation.

The 1812L200/16DR Resettable Fuse is a valuable component for many sensing and safety applications and can be found in a wide variety of electronic products. It offers the user a cost-effective means of circuit protection with better temperature tolerance and non-destructive features than traditional fuses.
