Replacing ASUS RT-N16 router capacitor

madlife23 187 124 May 3, 2014 at 11:38 AM More eBay Deals
The router stopped powering up and I decided to open it and noticed a blown capacitor.
The label on it says 680uF 16v 105*C and the brand looks like it says HERMEI it is purple and silver. I was wondering if these capacitors I found on ebay would be a good replacement? Is there anything else I should be checking for compatibility?
Thanks !

check the power supply's voltage with load. if bad caps in it, replacing cap in router will happen again.

can be replace with "bigger" ones(volt, capacity), so it's easier to find one on old parts.

if you can't find one and live in NYC, i can give you one.

First of all, there seems to be only one reputable capacitor dealer on Ebay, and it's http://stores.ebay.com/PC-MotherB...tors-Store

Lots of counterfeit caps are sold on Ebay, but the ones in your link seem genuine. Here's Panasonic's data sheet for those FR caps:

http://www.DigiKey.com is an authorized dealer of high quality capacitor brands like Nichicon, Panasonic, and Chemicon, and while their prices aren't the lowest, they're fairly cheap for small orders (no more than 8 ounces) because they ship by US mail.

http://www.BadCaps.net is another seller of high quality capacitors, and its forums are a great source of information about selecting the right ones. In addition to getting the capacitance, voltage, and temperature ratings right, you may have to also consider ripple current and ESR. Generally lower ESR is better, but in practice too low can cause unwanted oscillations in certain applications.

I agree buy from Digikey or Mouser, likely faster shipping too.

mouser doesn't seem to have any cheap shipping option, but an order from digikey [digikey.com] would be ~$4 which is about the same as the ebay deal (but it's a reputable seller, won't run into shenanigans with fakes/etc.)

although honestly I am not sure if it's even worth faking cheap components like this... the ebay deal is probably fine as well

I am on the page of the seller you linked for all 16 680uf caps, would any of these be a good replacement or do I need to check other things?

Probably any of them, but try to roughly match the impedance or ESR of the original Hermei. Also change only the suspect cap and try out the router, before changing any more, just in case the ESR/impedance is too low.
