Binding Posts Capacitor Card[edit]

  • 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
