The Bourns MF-LS190 is a polymeric PTC resettable fuse designed for overcurrent protection. It has a hold current of 1.9A and a trip current of 4.2A at 23°C, with a maximum voltage rating of 24V. The device can handle fault currents up to 100A. Initial resistance ranges from 0.030 to 0.057 ohms, and post-trip resistance after one hour is maximum 0.100 ohms. Time to trip at 23°C is 10 seconds maximum, with typical tripped power dissipation of 3.0W.
The operating temperature range is -40°C to 85°C, and the maximum device surface temperature when tripped is 125°C. The fuse is housed in a strap package measuring 22.35mm x 10.60mm x 1.10mm, with user-defined mounting. It is RoHS compliant. Common applications include rechargeable battery pack protection, cellular phones, and laptop computers, particularly in environments with elevated ambient temperatures.
