Yes these are correct, they are the fuses. Try replacing the F2. Get the right one with the correct size for your model.
But the question is why it breaks? There may be a short circuit or a temporary overvoltage. Check all ribons and connectors (they may get lose) that they are not damaged and correctly pluged in.

When your Nintendo console does not turn on at all or when charging becomes impossible, a quick trip to the fuses may be necessary...
On the 3DS XL model, two fuses are located on the motherboard, the first is at the charging circuit input near the transformer power plug and the second is right next to the battery contacts since it protects the main circuit.
Fuse F1 (3DS charging circuit):
Fuse F2 (main power 3DS):
Obviously we will avoid MacGyver-style repairs such as replacing them with aluminum foil, tin ball, wire, etc. If the fuse has failed, there is surely a good reason, so it will be necessary to check the absence of short circuit before restarting. It can however happen that they let go because of a small overvoltage and that finally nothing behind is HS. These fuses have the K mark so they are
1.5A fuses
