’s $50 Thunderbolt cable contains a total of 12 larger, inscribed chips, and tons of smaller electronic components, an iFixIt teardown has revealed.
Once the casing was gone, we had to perform a significant amount of desoldering and cutting in order remove the metal surrounding the connector. Peeling back the metal (which appears to be plated brass) revealed the hardware underneath.
We found two Gennum GN2033 chips in the connector, one on each side. They were flanked by other, much smaller chips that surely added to the cable’s cost: two chips labeled S6A 1JG on one side, and chips labeled 1102F SS8370 and 131 3S on the other. Of course, there were tons of little resistors (providing impedance as needed) all around the larger chips.
Take a look at unwrapped cable below…
