Pars Posted October 26, 2011 Report Posted October 26, 2011 I normally use FMs in most cases, but I see that they have come out with the FR series which are supposedly lower ESR, higher ripple current and longer life? Anyone use these, or are FM good enough? Or other? Use for now would be in PSU filtering for an I/V stage.
Mister X Posted October 26, 2011 Report Posted October 26, 2011 The primary advantages of the FR series are increased capacitance and endurance. ESR is the same as the FM series. Impedance and ripple current are also the same as the FM series for a given can size.... There are a few instances where increased capacitance has reduced can size which effects ripple current / power dissipation so its a good idea to double check the datasheet.
luvdunhill Posted October 26, 2011 Report Posted October 26, 2011 I use mostly the M series these days: http://www.panasonic.com/industrial/components/pdf/aba0000ce12.pdf
Pars Posted October 27, 2011 Author Report Posted October 27, 2011 ^ and particular reason you like these? They are less expensive, but also 85C, not 105C.
