16R900GF

16R900GF is a radial leaded PolySwitch PTC resettable fuse from Littelfuse, part of the 16R Series. It is designed for overcurrent protection in a variety of electronic applications, particularly USB and general electronics. The device has a hold current of 9 A and a trip current of 15.3 A at 20°C still air. It can withstand a maximum voltage of 16 Vdc and a maximum fault current of 100 A. The typical power dissipation in the tripped state is 3.3 W. The initial resistance (R min) is 4.7 mΩ, and the post-trip resistance (R1 max) is 13.5 mΩ. The time to trip at 45 A is 5.5 seconds.

The fuse is RoHS compliant, lead-free, and halogen-free. It is rated for operating temperatures from -40°C to 85°C. Packaging is radial, disc style with 5.10 mm lead spacing. The device dimensions are 14.00 mm length, 3.00 mm width, and 21.70 mm height.

Applications include computers and peripherals, USB port protection, and general electronics requiring resettable overcurrent protection. The 100 A short circuit rating ensures robust protection in fault conditions. The fast time-to-trip characteristic helps minimize damage to downstream components.
