Title: Need recommendation on sourcing the SMT capacitors for component video board
Post by: turbokon on June 03, 2013, 12:06:24 AM

I'm running into some snag with component video boards. There are some incorrect traces on the board so I had to cut a few traces and jump a some wires. I'm also running into issues with the SMT caps I'm using. Any particular SMT caps I should use for the 22uf, 220uf and 470uf? Both the 220uf and 470uf are polarized. I switched out the ceramic SMT caps for the thu hole aluminum electrolyte and the board works.

Looks like I'm going to have to scrap the idea of using 1206/1210 SMT cap size for the 220uf and 470uf that the component video boards need. I'm gonna have to go with the bigger radial leaded aluminum electrolytic caps.

solved
board works using 22uf caps for all locations

do either of you know how much amperage this pulls?
