47uF 25v capacitors can be used with any DC voltage up to 25V. 47uF 25v Capacitor have 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).
Tolerance: +/- 20%
Dimensions (excluding pins): 4mm (0.16") diameter x 7.8mm (0.31") height
Pin lengths: long pin - 24mm (0.95") and short pin - 19mm (0.75")
