This is a new old stock or current production Gold Cap supercapacitor, rated at 5.5 volts and 0.302 farads (marked as 302k).
It's a genuine component made in Japan, so you're getting that reliable build quality and performance.
The tolerance is rated at ±3%, which is pretty tight for a cap of this type.
Whether you're repairing vintage audio gear, working on a power backup circuit, or tinkering with microcontroller projects that need a little juice to hold memory or keep a clock running, this cap is a solid pick.
It's still in its original packaging, unused and undamaged.
Gold Cap is a known name in the supercapacitor world, so if you need to replace a worn-out one or just want a quality component on hand, this is it.
Just double-check your circuit requirements—5.5V and 0.302F is a specific combo, but it's great for low-power memory backup or similar applications.
