If you are drafting a 24V circuit with an 11A requirement, consider the following: Trace Width:
For 11A, standard 1oz copper traces may need to be extremely wide (over 400 mils) or use multiple layers and heavy copper (2oz+) to prevent overheating. Heat Dissipation:
Ensure there is adequate copper pour around the F4901 pads to act as a heatsink, as PTCs rely on thermal equilibrium to function correctly. Voltage Rating:
Verify that the specific variant of the F4901 you are using is rated for at least 24V (often marked as cap V sub m a x end-sub
). Using a PTC below its rated voltage can lead to device failure during a trip event. Decoupling: f4901 11a 24v schematic free
