Jaycar 4700µF 10V Low ESR Electrolytic Capacitor – Radial Leads, 2552 mA Ripple Current

You need more bulk capacitance at the rail and your current cap can't hold the ripple down. This 4700 µF, 10 VDC low-ESR unit from Jaycar is built for exactly that job. Polarised—positive terminal must always sit above negative—so double-check orientation before you solder. It handles 2552 mA rms of ripple current at 105 °C / 100 kHz, which covers most SMPS and linear supply output stages without thermal stress. Impedance is 0.028 Ω max (20 °C, 100 kHz), the lowest in this range, so your smoothed DC stays flat under load. Low D.C. leakage keeps self-heating down in enclosed chassis. Radial leads on standard pitch drop straight into most through-hole layouts. Add to cart and it ships from an Australian warehouse
