Hey there Chris,
I'm gonna tag @flannelist, since they have some good insight about the steam deck, and I will also link you to [post|847798|this answer] to help you out, but to give you the short summary the bigger component looks like a current sense R010 and the smaller one is either a 1206 or 0805 capacitor. You can actually see it on [guide|148928|Step 8 of iFixit's Steam Deck Motherboard Replacement|stepid=306467], and I marked it on the photo.
