What is PTC Resettable Fuses? PTC Resettable Fuses are polymeric Positive Temperature Coefficient (PTC) devices that protect electronic circuits from over-current conditions. It’s a resettable protection device based on a radiation source surrounded by a temperature-sensitive polymer. It is used in AC-DC power distribution, DC-DC converters, high current applications and battery packs.

NANOSMD380LR-2 is a PTC resettable fuse that operates on a principle of thermal inhibition. It is a small, 20mm metal encased component with an integrated thermal switch. The thermal switch triggers when an over-current is detected, and the current is shut off. Thanks to its low impedance characteristics, the NANOSMD380LR-2 is an ideal choice for applications where low power dissipation and fast response times are important.

NANOSMD380LR-2 is perfect for AC-DC power distribution, high current applications and battery packs. It helps protect electronics from current shock and short circuits caused by overloads and faults. It’s a safety feature that is easy to install and provides the necessary protection for valuable electronic devices.

NANOSMD380LR-2 features a wide operating temperature range of -30°C to +80°C and a wide current range from 0.2 to 180A. It has a fast surge response time and low power dissipation, making it a great choice for applications that require superior protection. The device is also UL recognized and RoHS compliant.

The working principle of NANOSMD380LR-2 is based on thermal inhibition. An integrated thermal switch triggers when an over-current is detected and shuts off current flow to protect the device or system from damage. The device can only be reset manually in the event of a trip and is not self-resetting. In order to reset the fuse, the user must remove the source of the over-current to allow the thermal switch to cool down and reset itself.

The NANOSMD380LR-2 is a reliable and cost-effective PTC resettable fuse solution for AC-DC power distribution, high current applications and battery packs. It provides fast response times, low power dissipation and superior protection for valuable electronics. It is UL recognized and RoHS compliant, and can help protect against electrical shock and short circuits.
