Binding Posts Capacitor Card
- Would be good to add caps on the binding posts to suppress switching HF noise components
- Gets messy with leaded parts
- Binding post spacing 0.75" (niminal)
- Might be some slop due to hole drilling slop
- Use "horizontally" elongated holes for binding posts
- Use ceramic caps
- Pads for 3x of 0805 SMT
- Good values 0.1uF, 0.01uF, 0.001uF
- Pads for 1x of 1210 SMT
- Good value 10uF
- Connect to card with up to 12 AWG wire
- Alternately 4-40 screws
