Just in case the OP, or someone else that wants to go down this road, |
98 |
wants to repair this. This is the list I go by. Link first, then list |
99 |
of top tier in case one wants to skip reading the whole thing. |

All Japanese caps are considered of high quality, and we like to see the |
106 |
following cap brands: |
107 |
|
108 |
* Rubycon |
109 |
* United Chemi-Con (or Nippon Chemi-Con) |
110 |
* Nichicon |
111 |
* Sanyo/Suncon |
112 |
* Panasonic |
113 |
* Hitachi |
114 |
* FPCAP or Functional Polymer Capacitor (ex-Fujitsu caps segment, |
115 |
which was bought by Nichicon) |
116 |
* ELNA |
117 |
|
118 |
Besides Japanese manufacturers there are also several US and European |
119 |
vendors that make high-quality capacitors. Probably we won't meet any of |
120 |
the below cap brands inside a consumer grade PSU, at least their |
121 |
electrolytic offerings, but we decided that it still worth mentioning them. |
122 |
|
123 |
* Cornell Dubilier (USA) |
124 |
* Illinois Capacitor (Currently owned my Cornell Dubilier) |
125 |
* Kemet Corporation (USA) |
126 |
* Vishay (USA) |
127 |
* EPCOS (TDK company, Germany) |
128 |
* Würth Elektronik (Germany) |

As a person who has built circuits and such, for long term use I try to |
132 |
stick with Rubycon, Nichicon or Panasonic if I have to. Sometimes if it |
133 |
is a short term project, I'll use 2nd tier. I've had several 2nd tier |
134 |
caps fail. Besides stinking up a room, they can lead to the failure of |
135 |
other components. I replaced two 2nd tier caps in a power inverter not |
136 |
long ago. Luckily it was on the power input and I had the switch turned |
137 |
off. They blew their smoke as soon as I touched the wire to the |
138 |
battery. No damage, just smelly. |

Good luck to those who tinker. :-D |
