Jaycar 4700µF 25VDC Electrolytic Capacitor – RB PC Mount | RE6244

That low-voltage rail is still bouncing and your 4700µF cap has puffed out or dried up. You need the right value back in the circuit before the board sees another power-on cycle. This Jaycar RB electrolytic gives you 4700µF at 25VDC with a 2150 mA ripple current rating – plenty of margin for a 12V or 15V supply doing real work. Through-hole leads, standard pitch, solder and go. Polarised: positive above negative, no exceptions. Grab it and stop guessing at capacitance values

• 4700µF capacitance at 25VDC – high-capacity smoothing for low-voltage rails
• 2150 mA ripple current rating for sustained filtering under load
• RB (radial board) PC-mount, standard through-hole leads
• Polarised – positive terminal must always exceed negative voltage
• Commonly used as LPF in power supply input and output stages
