Mr. Hansen, just wanted to say thank you for making public your API mod and DI stuff.  Your web pages are something I return to often!

This PC card must be mounted in a metal box, and especially in this case where the OEP transformer is used, since it does not have a mu-metal screen.


But you can get a MuMetal can for the OEP.

The metal needs to be ferrous - ie steel (not aluminium) to provide any shielding of a transformer against magnetic fields

Of course it is best with the option mu-metal screen, but even if this was already mounted on the transformer, the PC card must be mounted in a metal box.

Oh yes the case is best a metal case in any err... case.
Just pointing out that there is an optional can for the OEP transformer.

Hi everybody !

Does someone still have the self-etching papers  ?
Links in this topic and in the Bo's website seams to be dead...

It would be helpful !

Thanks !

Good day to everyone.

I noticed that there are two issues with the Mouser project list, namely that 512-1N4004 is discontinued and 71-RN60D3901F is backordered until 9/2019. 

Will it be a problem to replace the rectifier with Mouser's suggestion? https://www.mouser.com/ProductDetail/863-1N4004RLG?&bdprt=1&projectguid=E23CB3E7-9EF8-4003-898F-8416D6654D75&projectid=87542205

Unfortunately I am not very knowledgeable about specific components, so can someone recommend another resistor to avoid waiting until September to complete this project? I've checked a few other distributors but haven't found RN60D3901FB14 available anywhere yet.

Thanks in advance for your help!

1N4004 is a rectifier diode, you should be able to substitute another brand 1N4004 without problem.

I assume this is a through hole PCB layout... I didn't see spec sheet data on the other part.  If they are the same package the electrons will not care.

I will confirm what JR said from building several of these. Any through hold 1N4004 will do. I would just do a part search on Mouser (or whomever you prefer to use) and which ever one came up that was in stock and inexpensive I would use that.

Thanks!

I cant imagine the voltage swing in this being more than 100v. Is there a particular reason 1n4004's were used vs 1n4001-4007 or will any of these do in this application?

I meant to say "through hole" not "through hold," but I think you get it.

Pushbroom,

As many have already said, you can use the 1 amp. diode of any of 1N4001 to 4007 series, why I just chose 1N4004 is that it is most commonly used.
