Overview

The MF-R110 is a resettable Fuse made by Bourns in a 插件,P=5.08mm package with 2 pins. -40℃~+85℃ 1.1A 100mΩ 2.2A 270mΩ 30V 40A 6.6s 700mW 8.9mm 插件,P=5.08mm Resettable Fuses ROHS.

PCBKit's library has its KiCad symbol (Device:Polyfuse, from KiCad's library) and its footprint (Fuses:FUSR_BOURNS_MF-R_STYLE1-D8.9MM, from CERN's library), ready for a KiCad board. 1,991 are in stock at JLCPCB (part C208481). 5 open-source boards in 3 repositories on GitHub use it.

Questions

Is there a KiCad symbol and footprint for the MF-R110?

Yes. The symbol is Device:Polyfuse and the footprint Fuses:FUSR_BOURNS_MF-R_STYLE1-D8.9MM, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MF-R110?

插件,P=5.08mm, with 2 pins. Its footprint is drawn on this page.

Where is the MF-R110 datasheet?

Bourns publishes it: the Datasheet link on this page opens it.

Where can I order the MF-R110?

JLCPCB lists it as part C208481, with 1,991 in stock; the sellers' links on this page open their listings.

What can replace the MF-R110?

Parts like it in the library: the MF-R050 by Bourns and the MF-R090 by Bourns. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the MF-R110?

5 boards in 3 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
