PTC Resettable Fuses have been around for some time now and are increasingly being adopted in modern consumer and industrial electronics applications. The 1812L035/30DR is a type of resettable fuse, which is designed for a variety of applications, and has a wide range of operating parameters. It is typically used in low-voltage DC electronic systems and can be applied to further circuit protection in the range of 3 to 30 Volts.

The 1812L035/30DR is a particularly popular resettable fuse choice because it offers excellent protection properties in addition to its ability to reset quickly when current is reduced to a safe level. It is also designed to act quickly to protect against voltage surges, providing peace of mind in situations where rapid response is important. Its temperature rating is from -55°C to 125°C, making it suitable for a variety of operating conditions.

The 1812L035/30DR is a positive temperature coefficient (PTC) device designed to match the levels of temperature, current and voltage of the application it is intended for. The device is constructed of ceramic materials and gold-plated terminals. It features a lead design that connects the broken circuit electrically and thermally which allows the device to detect when the current begins to drop, triggering the device to turn off the current.

When the device is operated at the specified level of current, it reaches its current trip point and the current causes the PTC Resettable Fuse to enter a phase known as the “x-state”. This is when the current path is blocked and there is no electrical contact between the terminals. However, when the temperature of the device drops to room temperature or below it, the circuit path is restored and the device is returning to its “on” state. This is referred to as autoreset.

The 1812L035/30DR PTC Resettable Fuse is usually fitted onto printed circuit boards and is a preferred choice in portable consumer electronic devices as its small size and fast reset time make it ideal for use in these applications. This device is ideal for those applications that are concerned with power supply 24/7, as the reset time is very short and it will not fail to reset the circuit when the operating parameters are eliminated. It also provides the ability to protect against unexpected overloads caused by voltage and current surge.

The 1812L035/30DR is also suited for industrial use in controlling the current flow of heavy motors; however, it is important to note that since the device is a PTC type device, it has lower current carrying capacity than traditional fuses. Due to this, careful consideration should be taken when selecting the device for these type of applications, to ensure it will provide the necessary protection required.

In conclusion, the 1812L035/30DR is a popular type of resettable fuse for use in a variety of applications, ranging from consumer electronics to heavy motor control. It provides a wide range of protection and is designed to act quickly when dealing with current surges or voltage spikes, making it ideal for those applications that require fast response times. As such, it is an excellent choice for anyone looking for an effective resettable fuse for their application.
