Jaycar 10µF 50V Bipolar Electrolytic Capacitor | Non-Polarised RB Type | 48mA Ripple

You need a 10µF cap on a line where the polarity isn't fixed. A regular electrolytic will fail the first time current reverses. This bipolar unit is built for exactly that: two anodes in series, 50V rating, 48mA ripple tolerance. Solder it in either direction and stop worrying about orientation. Your circuit stays alive

• Non-polarised – connect either way, no polarity marking to second-guess
• 10µF capacitance at 50V working voltage
• 48mA maximum ripple current rating
• Two anodes in series (RB bipolar construction) for AC or reversed-DC circuits
