[Jonahsniper]

Hello,

We are helping customer to repair a board. There is few components on it that no fruit on Google. I attached the photos and a drawing with(part code: T199). Anyone have ideas about this one?

The markings:

Y 504 448 B
15124

9204T

Quite heavy for its small size.

Thank you in advance.
