microSMD450LR Datasheet | Littelfuse

Description Poly Switch® low resistivity SMD (surface-mount device) is a versatile device well suited for general applications which have space-constrained, low power dissipation and high environmental reliability requirements. The devices can help provide both overcurrent and overtemperature protection for battery pack PCMs (protection circuit modules), circuit PCBA and signal/power I/O interface. The resettable feature ensures the device will “Trip” and protect the application during the faults and yet regain the functions once the error is removed. Features - Current ratings from 1.75 to 6.0A - Maximum electrical rating: 6VDC and short circuit current 50A - Halogen free (Br≤900ppm, Cl≤900ppm, and Br+Cl≤1500ppm) - Ultra low internal resistance - Automatic Reset - Ro HS plaint, lead-free and halogen free Applications - Mobile and smart phones - Wearable devices - Portable game console - VR/AR head mount display (HMD) - Tablets and e Book - Portable printer and projector - Li-Ion battery Powered Mobile Devices - USB Connection Ports © 2017 Littelfuse, Inc.
