Jaycar 220µF 16V Low ESR Electrolytic Capacitor – Radial Leads, 640 mA Ripple Current

Your regulator input needs a little more capacitance than a 100 µF can give, but you're not in the 2200 µF territory. This 220 µF, 16 VDC low-ESR cap from Jaycar sits right in that gap. Polarised—positive terminal must always read above negative—so check orientation before you solder. It handles 640 mA rms ripple current at 105 °C / 100 kHz, which covers most mid-current linear and switching regulator inputs. Impedance is 0.13 Ω max (20 °C, 100 kHz), keeping the smoothed rail steady without a large thermal budget. Low D.C. leakage keeps things cool in tight enclosures. Radial leads on standard pitch are a direct fit for most through-hole layouts. Add to cart and it ships from an Australian warehouse
