Used these as basis to do an internal metal-work design to meet CISPR11 class B with 6 to 10 dB margin for the project using a T3.2 just shipped. Could not use metal box, and did not want expense of plated plastic box, so did a shield for PCB that the T3.2 was mounted on. Added benefit was that, as the signal processing is separate board, ENOB went from 9.8 to 11.2 - woohoo.
Dunno how much this stuff costs to buy pre-mfr, but for raw materials+labor, is under 1.30 USD per box at Mexico factory.
