Polymer Capacitors - Radial Lead

Sanyo OS-CON Polymer capacitors : These do not have electrolyte they have polymerised organic semiconductor instead, so do not have the same failure problem. Therefore they do not have a vent on the top even though they are Low ESR. They are much more effective than electrolytic caps so you need lower values than before. Expensive caps.



Sanyo OS-CON SEPC Series. Sanyo's top polymer series typically found on vcore of high end boards or on graphics cards.

Sanyo OS-CON SP Series. Note that they clearly say OSCON on them and the SP series is clearly indicated. The strange purple colour is exclusive to most of the series of OSCON caps. These are available in larger capacitance than SEPC but the ESR is higher though. The leads can be too big for the holes on some boards or graphics cards though.

Everybody please contribute photos and explanation of the identifying marks of GOOD Low ESR capacitors for motherboard applications.

Aluminium Electrolytic Capacitors - Radial Lead

Rubycon MCZ. A row of black with gold stripe Rubycon MCZ. Rubycon's top series

Ruybycon MBZ. The dark purple cap indicated with the arrow. After MCZ they are the second best in Rubycon's series for motherboard applications because of their very low ESR. General availability is difficult. Topcat of these forums can sell you this range in 8mm sizes which are even more difficult to find.

Rubycon ZL. A very popular series for motherboard applications. Note the Black colour, The Rubycon K vent marking (many other companies use K markings though, note the style of the Rubycon K marking and that it is quite a deep thick cut unlike the counterfeit ones) also note the Rubycon logo and the cap range namely ZL is clearly noted. Along with Panasonic FC series, general availability is good. ZLH has longer life than ZL series though at the same ESR rating. ZA/ZLG series are the next step up in lower ESR than ZL/ZLH with ZLG having longer life than ZA.

Rubycon YXG. Same remarks as above, dark blue/purple colour instead. Not as good as ZL series but perfectly adequate also. YXH series has longer life than YXG though but with the same impedance specs.

Panasonic FC. Note the T vent marking which is exclusive to panasonic. Note the M character in a box which indicates Matsushita the parent company of the panasonic brand. Note the navy colour, they also come in black, note the gold negative stripe which is on both colours. Note the FC after the +105oC which indicates they are FC range. There is also FA series which is better but FC series is excellent for motherboard applications and general availability is good.
