That’s the “series diodes” option here: > [@Typical module power circuit](https://lookmumnocomputer.discourse.group/t/typical-module-power-circuit/1134/3): > > Different schools: 10 ohm and capacitor near power header (this basically results in an RC low pass filter, but with a voltage drop over the resistor depending on the current). Usually somewhat pointless (the resistors, not necessarily the capacitors). 10 ohm without capacitors (either using them as fuses, expecting them to die if something’s shorted, or possibly just cargo culting, trying to do the above but forgetting how things work, see “power sins” [here](https://northcoastsynthesis.com/news/design-mistakes-in-synth-schematics/) for more). Ferrite beads (if done … (I prefer diodes to ground myself, but that assumes that you only use power supplies that can deal with a short.) --- _[View the full topic](https://lookmumnocomputer.discourse.group/t/contemplating-the-circuitbenders-drumbs/2771)._
