Need help identifying component
vinovino:
Need help identifying the component and a possible replacement parts.
The designator says FL14, I think its a kind of filter but I don’t know what kind.
It has 3 pads underneath, the middle pad is connected to ground.
It is around 2mm size.
Please see attached images of pad and the filter itself beside a ruler.

What is this out of?
FL20 also looks cracked.
u666sa:
FL15 looks normal. You can take it off, rig it up and measure it with NanoVNA. It's a coil, two coils with ground in the middle. Unless FL15 pin to ground does not measure as coil, then it is a capacitor, but the marking say L, so I suspect a coil.
All these 3 components should have same exact values. Measure FL15, and use two small coils (or caps if it is a cap) in place of one.

woul be as mentioned FIlter line smd inductive most of the time, but some do include capacitors ...

Could FL15 and FL20 (and FL14) be T filters?

Did someone replace FL20 (and FL15) with the wrong part and end up shorting it to ground? Is the centre pin grounded (yes it is, I just reread the OP)??
