It's essential to be able to read '''capacitor codes''' in order to correctly recognise the correct part and as the schematic, BOM and component supplier might use pF, nF or µF interchangeably to be able to

=== Stripe ===
If there is a stripe on a non-polarised capacitor, it might indicate which lead is connected to the outermost foil. To connect the capacitor connect this lead to the lowest impedance (usually the ground) side of the circuit. Many modern capacitors are unmarked, and often when a capacitor does have a stripe, it’s not related to the outside foil marking.<ref>[https://www.nutsvolts.com/magazine/article/finding-the-outside-foil-lead Finding the outside foil lead] by Chris Prioli, Nuts and Volts, Issue 2, 2022, p. 12</ref><ref>[https://e2e.ti.com/blogs_/archives/b/thesignal/posts/pcb-layout-tricks-striped-capacitors-and-more PCB Layout Tricks—striped capacitors and more] by Bruce Trump, The Signal, 11 Dec 2012</ref>
