Your buck converter is running hot and the output ripple is creeping past spec. A standard electrolytic just won't cut it at this frequency – you need low impedance where it counts. This Jaycar 1000µF 10V low-ESR cap sits at 0.06Ω max impedance at 100 kHz and handles 1210 mA rms ripple at 105°C. That's the difference between a clean rail and a noisy one. Rated for 2,000 to 4,000 hours under load at 105°C, so it's not a throwaway part. Radial leads on standard pitch – drop it into your PCB and test the ripple again. Add to cart
