When I was studying power supply electronics in school, the instructor always talked about adding BFC’s to the circuit - Big Freakin’ Capacitors. This here is UHFC … read more

Do you have a charging circuit for the super capacitor?

Hi Scott, I believe we spoke on the phone about this today. Unfortunately, we don’t have a charging circuit for these - I have noted it down as a suggested item for us to stock in future so thank you for that.
If you were looking for more Super Capacitors in stock we also have a 100F version (though it may not be large enough for your purposes): https://core-electronics.com.au/super-capacitor-100f-2-7v.html

If you don’t need minimum charge time (and efficiency isn’t too critical, say if you’re charging from a mains connected DC power supply) a resistor is always pretty effective. It’ll approach your source voltage asymptotically that way.
Just check your resistor can handle the heat - Power rating will need to be at least V*I Watts. You may need a power resistor:
