3 ohms/volt dropper (5v = 15R dropper) to limit the surge was the standard
I learnt and still use.  Suitably adjusted/amended to allow for the load
current.

However I can not find the design notes that the value comes from, I have
got them somewhere.  The likely source is a Siemens databook from the 1980's.
