MF-LR900/20-0 is an axial leaded PTC resettable fuse designed for overcurrent protection in low-resistance applications. It features a hold current of 9.0 A, trip current of 16.7 A, and maximum voltage rating of 20 V with a maximum current rating of 100 A. The device has very low internal resistance with initial resistance ranging from 0.006 O minimum to 0.010 O maximum at 23 °C, and includes weldable nickel terminals. Operating over a temperature range of -40 °C to +85 °C, this RoHS compliant fuse is ideal for rechargeable battery pack protection, cellular phones, and laptop computers where low resistance protection is required.
