Adafruit like capacitors so much they made a kids show about them. They're super handy and it's really helpful to have a variety lying around to pick and choose from.
This is a 10 pack of 47uF 25v capacitors, so they can be used with any DC voltage up to 25V. They have a tolerance of ±20% and long flexible pins that make them great for perf or breadboards. Remember that electrolytic capacitors are good for low frequency filtering (~1KHz or less), for higher frequency, pair up with a ceramic capacitor
Adafruit use these capacitors in Adafruit's own kits and they're great quality. They're so useful they're selling them in packs of 10. Each has nice clear labelling on the body as theyll in case you have a capacitor mix up.
