Replacing Capacitors With Different Values Guide
Once the new capacitor is ready, heat up your soldering iron and carefully remove the old capacitor from the board. If it''s a through-hole component, simply desolder each of its leads separately. If it is a surface-mount component, heat up the solder pads and use tweezers to gently pull it away from the board.
