UCD3138: RHA vs RJA

Jack Tan80

Part Number: UCD3138

Dear UCD expert,

I see RJA was highly recommended to use in datasheet. But can you please help me know what are the risks of using RHA compared with RJA? Since currently RJA seems shortage in market, but RHA better. Thanks...

Hello Jack,

Please refer to the second page in the UCD3138 Datasheet.

I understand that in some Telecommunication applications, where the PCB is very thick and BLR cycling test results are critical, the RJA offers the required level of reliability.

Hi Yizik,

Thanks for this info.

Can you please help give some numbers about the thick PCB? In my cases, the PCB has 12 layers, can I call it as thick PCB?

Hello Jack,

I believe you can call your PCB thick.
