This is a circuit design question and outside the scope of this KiCad forum which is for discussing the KiCad software. Just because a symbol is found in the KiCad libraries doesn’t mean design questions about it should be posted here. Try another forum like EEVblog or the Electronics stackexchange.
oh, sorry… I figured schematic went hand in hand with kicadforum…
It’s not just about the schematic. It’s part of a circuit design and even another forum would struggle to give you an answer without the context of the complete circuit.
