Hi!
Can any one please help me to find difference between Shielded Drum Core and Un-Shielded Drum Core?
Also,can you please share pictures of Shielded and Un-Shielded Drum Core?

Thanks!

For a given LI^2 product, an unshielded core is usually cheaper. But it has lots of stray fields which can couple into sensitive components.
