You're mid-build, the schematic calls for 2.2µF, and you'd rather not wait a week for a generic marketplace to finally ship it. This Jaycar 2.2µF electrolytic is rated to 50VDC and 85°C, with leakage characteristics that sit close to a tantalum cap at a far more reasonable price. Polarized – positive terminal must always exceed negative. Use it for power supply filtering, input/output smoothing, or LPF stages. Grab it and get back to the board
