Key Features

The SMD050F-2 is a surface-mount PPTC resettable fuse designed to provide overcurrent protection in electronic circuits. With a hold current of 500 mA and a trip current of 1 A, it effectively safeguards against short circuits and overcurrent conditions. The device can withstand a maximum voltage of 60 VDC and interrupt currents up to 10 A. Its fast response time, tripping within 4 seconds at 8 A, ensures timely protection. The compact 2920 package facilitates space-saving designs, while its resettable nature allows the fuse to return to a low-resistance state after fault clearance, eliminating the need for replacement.

Applications

Overcurrent protection in consumer electronics
Power supplies and adapters
USB peripherals
Telecommunication devices
Industrial controls

Product Overview

The SMD050F-2 from Littelfuse offers reliable and resettable overcurrent protection for various electronic applications. Its polymeric PTC composition allows the device to transition from a low-resistance state to a high-resistance state when an overcurrent condition occurs, effectively limiting the current flow. Once the fault is removed and power is cycled, the fuse resets to its original state, providing continuous circuit protection without the need for manual intervention. The device’s small footprint and surface-mount design make it suitable for high-density circuit boards. Its wide operating temperature range ensures performance in diverse environmental conditions.
