Mystery electronic component - BBSHD Controller

[Mdu]

Hi Everyone,

While attempting to do the BBSHD 50 amp Shunt Mod (details here - https://endless-sphere.com/forums/viewtopic.php?t=83778 ), I managed to un-pick one of the board components .



I'm guessing the board is now a write off, but out of interest, does anyone know what the component is, or what it does?

Thanks in advance!

It's a bit difficult with only the top view but it looks like an smd inductor.
So it's basically a ferrite core (which is brittle) with some windings on it.
You might be able to find replacements on electronic component webshops, but besides it's value they also have a maximum allowed current and an optimal operating frequency.
(Depending upon the type of ferrite used.)
They are often used in step down converters. If you have a step down integrated circuit nearby, it's datasheet usually shows some 'use examples' and the inductors that can be used. Most of the time, such reference design is used.

An smd inductor, that's given me starting point, hopefully I can find a replacement.

Thanks!
