I am using TPA2000D1 class D audio amplifier in my PCB. Now we are going for CE certification for which we have to do through EMI/EMC tests. If you see the datasheet of the amplifier (page: 16) they have told to use ferrite chip bread and they have given part number also NEC/Tokin: N2012ZPS121 but it is not available with any electronic distributor (Digi-Key, Mouser) . Can you suggest any active in stock part that can be used instead of NEC/Tokin: N2012ZPS121.
For the radiated emission the frequency measurement starts at 30 MHz and the max frequency generated by the class D amplifier is 300 KHz, so how it will affect the radiated emission.
Can we use LC filter, how LC filter compared against ferrite chip bread filter.
Regards,
Tapas
