Does brand matter for SMDs in high end audio?

Hi,

I’m looking to replace all the SMDs in my Krell amplifier. Can anyone recommend good replacements? I’ve attached a photograph of the board. Just not sure what the best brand is for these and which part number.

I assume the are 47uf, 35v SMDs rated to 105C. Same question applies to the other SMDs.

Thank you all so much in advance.

I see 2 that are the 47uf, 35V on your board. If you are looking for a replacement, we need to know the dimensions of the plastic base at the bottom. That ensures they will fit properly on the board.

Thank you, i’ll measure straight away. The others - 6v 47uf and 25v 10uf - are they polarised at all ? I don’t see a black mark at all indicating the negative side ?

Hello,

Here is the link for the 47uf 6.3v: Aluminum Electrolytic Capacitors | Electronic Components Distributor DigiKey
link 47uf 25v: Surface Mount Aluminum Electrolytic Capacitors | Electronic Components Distributor DigiKey

You can review the options and choose what is closest to the size you measure on the board.

FYI - SMD = surface mount device

What you are asking about are aluminum electrolytic capacitors, and in the pics they look like through hole mount not surface mount.

Hi Paul,

Apologies I should have been more specific - I wanted a replacement for the SMD capacitors rather than other through hole ones.

Best wishes
