| 1421684 | 2016-06-12 08:49:00 | You are best looking up the datasheet for the original ones (they will have a series marked on them, either 2 or 3 letters usually) and making sure the ripple-current rating is the same or higher, and that the ESR is the same or lower (but not too much lower). Lower ESR is not an issue (ESR = Equivalent Series Resistance) and a lower ESR simply means that the internal impedance is lower, which in turn means that the capacitor will not dissipate as much energy, hence generate less heat. That is a 'Good Thing' and does not affect the performance of the capacitor, but may well improve the performance of the device in which it is installed. Cheers Billy 8-{) |
