Not sure what these are. They have 8 pins (4 in 2 rows)

Do you have any intent to measure ohms?

 

Hello,

@uraniumhexoflorite,
Not sure what these are. They have 8 pins (4 in 2 rows)
This could be a filter used in the ethernet line, when there are four pairs that have 0 Ohms when you measure it.

No clues about this one.
This is a 10.7 Mhz ceramic filter.

At first I thought this might be a gunn diode, but I realized that it probably wasn't, so I have no idea what it is.
This is likely a feed through capacitor.
