00:06you already know that hunting down reliable replacement ICs can be a total headache.
00:11So today, I've tracked down the best deals on the top 5 QFN IC chips and repair essentials
00:16for your electronics workbench that'll save you both time and serious cash.
00:20Kicking things off at just $6.20, we have this pack of 10.7MHz crystal filters.
00:27While this one rocks that classic 3-pin through-hole package alongside our surface-mount lineup,
00:32its sharp narrow-band pass filtering makes it essential if you're fixing radios,
00:36if stages, or communication gear. With thousands sold and a perfect 5-star track record,
00:42it's an easy staple to keep tucked away in your parts organizer.
00:45Next up is a true micro-soldering lifesaver, the BQ Series Battery Management QFN chips,
00:51running around $4.11 for a 5-pack. Whether you need the BQ246,
00:56715 or the popular 735 variant, these are the exact power-charging controllers you constantly
01:02see failing in modern laptops. Having a set on hand means you can revive a completely dead
01:08motherboard that refuses to charge, without waiting weeks for slow shipping.
01:12Coming in at number 3 for just $2.62 a pair, we have the SM41 Series LCD Power Management ICs.
01:20If you ever troubleshoot TV T-Con boards or monitor displays that have sound but absolutely no image,
01:269 times out of 10, one of these little chips is shorted out. They solder down cleanly with a hot
01:32air station, and at this price, it's practically a no-brainer to grab a couple for your next screen
01:36restoration. At number 4, we have the legendary M92T36 QFN40 chip, priced right around $7.66.

01:56without hassle, and with thousands of verified 5-star fixes, it's the ultimate go-to component
02:01for console technicians. Finally, sitting at $7.32, is the NB7N621M QFN38 HDMI Retimer IC.

02:16or signal
02:17dropouts, even when the physical HDMI port looks totally fine. It restores clean digital video
02:23output, and considering how much a replacement console costs, grabbing one of these to bring
