Jaycar 22µF 50V Bipolar Electrolytic Capacitor | Non-Polarised RB Type | 82mA Ripple

Bigger capacitance, same polarity problem. You need 22µF on a line where current can run either way and a standard electrolytic just won't cut it. This bipolar cap handles both directions: two anodes in series, 50V rating, 82mA ripple headroom. Drop it in the circuit, solder, and stop worrying about which pin is positive. It doesn't matter

• Non-polarised – either orientation works, no polarity to check
• 22µF capacitance at 50V working voltage
• 82mA maximum ripple current rating
• Two anodes in series (RB bipolar construction) for AC or reversed-DC applications
