Hahaha this is so funny! I am happy that someone is still using my device!

Hi Guys,
?
Like to check with you all some things 
?
I check the spec on RONJA web site and the BOM list state the Value for the cap is 
?
5u/16 V but when I did a check with the www.distrelec.com web site which state the part ?812217 ( as in Ronja web ) it is a 4.7u 50 V chip NTC-T475K50TRD So is it a 50 V part or a 16V part? 
?
next is case D too big? Cause I am having soldering it as I got from Kemet T491D475K050AT . Can this work ? 
?
Thank you 

Wallace Yaw 

Cheers always!!! Stay Happy My friends!

That is just the voltage rating, the voltage rating doesn't effect the
capacitance, so any voltage rating above 16V (if that is what was called
for) would work as long as the capacitance is close enough.

Maybe the network is somehow misconfigured?

It is an at-least-16V part.

Case D is OK

thanks for the reply , but no , it's not a network issue , it turned out to
be soldering issue .. the thing is working fine now .
