You may have noticed over the course of the past few months that common value capacitors (0.1uF, 1.0uF, 2.2uF, 4.7uF etc.) in case sizes ranging from 0402 and up have become exceedingly difficult to locate stock of. You may have been impacted by this in terms of us suggesting or requesting substitutes for parts that may be on your builds due to sourcing issues after an order has been placed.
In short, we are in the middle of a global capacitor shortage the likes of which the electronics manufacturing industry has not experienced since 2008…and this time the market for these parts is even worse. There are multiple causes behind the current situation, but the two biggest contributors are supply and demand.
