Hi guys,

i am currently repairing an FFR module from a Man truck. During my probing I came across these components (4x in total) and i have no idea what they are? Metal square components with what looks like resin between the plates. They test straight through continuity, but I do not know if they are supposed to or not as i have no clue what they could be.
Any help would be greatly appreciated.
Number on them is X030 LMAZ (the “X” may not even be an X but perhaps 2 interlocking chevrons).

thanks.

 

Might be Current sensors.
Just low ohm resistors

 

Ahhh! Yes! That makes sense.
Thank you!

Regards
Steve.

That is a Littlefuse PolySwitch resettable PTC overcurrent protection device.
