Fit andsoldercapacitor C5.
ThePCB allowsfor a radial or axial capacitor.In order to build a lowprofile board,
the capacitorshould lay onits side. An axial capacitorwould bemost secure inthis
configuration, but thereis limited length allocated and youprobablydon’t have one!
Youcan fit aradial capacitoron its side,butit is not as secure as an axial packageas
both leads come outof thesame end.
It
