PTC Resettable Fuses have become increasingly important in many applications, as they offer excellent overvoltage protection and can be reset quickly without the need to replace any mechanical components. The MICROSMD350LR-D-2 PTC resettable fuse is a protection device used in a wide range of applications.

The MICROSMD350LR-D-2 is a polymeric positive temperature coefficient device that consists of a body, a thermal element, lead wires, and two terminal pins. It has an operating voltage ranging from 16 volts to 42 volts, with a body size of 3.2mm in diameter and a height of 1.4 mm. The current rating of the MICROSMD350LR-D-2 is 350mA.

The application fields of the MICROSMD350LR-D-2 PTC resettable fuse covers a broad range, including industrial, automotive, and home appliance, as well as any other appliance that requires an overvoltage protection. It can be used to protect overcurrent and overload of electrical circuits, and provides excellent short circuit protection and inrush current limiting protection in a wide range of application fields.

The working principle of the MICROSMD350LR-D-2 PTC resettable fuse is based on its self-resetting ability. When the current through the device exceeds the rated current, the rising temperature of the thermal element causes the temperature coefficient material to activate and trips the device. Once the overcurrent is removed, the device will reset itself automatically. By this principle, the device can effectively provide overcurrent protection from 16V to 42V, whereas other types of protection devices have limited working voltages.

The MICROSMD350LR-D-2 PTC resettable fuse has proven to be an excellent device for overvoltage protection. It is easy to install and can be reset quickly. Most importantly, unlike the conventional fuses, the MICROSMD350LR-D-2 does not require the need to replace any mechanical components, resulting in a much lower cost of ownership. Therefore, it is highly suitable for a wide range of applications in the automotive, industrial, and home appliance markets.
