emi filter source

[satde]

Good day to you who are reading this.

Where does one get these emi filters that the saturn is so peppered with?

DSS1NB32A101Q55 looks like what I would want, my usual places do not have these.

Found some japanese vendor that has these but want a min 300 usd order and you have to be a company.

Has anyone used any alternatives successfully? Any tips on where to get these? Is it a good idea to scavange filters from unused lines?

Thank you.

The DSS1NB32A101Q55 has a thickness of 3mm so it probably won't fit. I know I tried the EMI101T-RC before and that was 3.2mm and it was too large - I had to make the filters all angled like a flower bouquet so they all fit in a row. I'm not sure if 3mm vs 3.2mm is enough of a difference for this to not be an issue but this was something I had a problem with.
EDIT: I got the wrong paper, it seems the DSS1NB32A101Q55 is 3.5mm thick, which is most likely way too much, considering that I had problems with a 3.2mm one.

From my research it looks like the DSS6 is the ideal replacement part but I've yet to try it since I still have a bunch of the 101t's remaining.
According to the spec sheet, the DSS6 should be 2.54mm thick only, so it should have no problem fitting in. They are all 101 types, with a capacitance of 100pF, which is what you need according to the service manuals.

The DSS6NC52A101Q55B is what I have written up as a replacement part to order, but it seems to be no longer produced nor offered for sale on the larger shops I checked. Hm.

Looked around a bit, it seems the DSS1NB32A101Q91A is available at Digikey and Mouser. It should be the same as the Q55B part, except that it comes in tape packaging and has slightly shorter leads, which should not be an issue.

However it is still too thick from my experience. You may try that or the EMI101T-RC, but I know for a fact that that one is too thick, and the specs say the DSS1 is thicker.

The DSS6N would have been ideal but it was discontinued in 2019. Damnit.

Scavenging the parts from dead consoles is probably not a good idea. I've heard of cases where they did not do their job anymore and had to be replaced, so it follows that they can get spent/broken, and so they'd need to be replaced with new parts.

Did not expect such a quick, in-depth and relevant reply.
Thank you very very much.

If you do end up replacing the filters, please be a peach and tell us what parts you got and whether they fit.

And what, if any, difference they make. I've done full recap + filter replacement once and it made the console more stable (the reason I did it was because it kept crashing), and it also made the screen more stable and the colours more vibrant. I've only replaced the emi filters on the video output + all the caps on the motherboard.

hi guys sorry for this bump, i was wondering if you guys could tell me which Emi Filter you guys are using for Sega Saturns ? i read the above but it seems like noone really answered which one is ideal since they discontinued DSS6NC52A101Q55B ?

EMI101T-RC is almost perfect. it's a bit too thick (3.2mm) so you need to put the filters in a bouquet shape (the leftmost will need to be bent to the left a bit, and the rightmost to the right side - start from the middle one to fit everything easier). If you just replace 1 piece, it may not fit, but it's better to go all the way and replace all the filters on the A/V out anyway, even if it's extra work.

DSS6NC52A101Q55B was perfect but has been discontinued long ago.

hey thanks for that reply, i really appreciate it and yeah i was gonna replace all of them might as well do it since i already recapped the whole board with exception of the emi filters thanks again   you wouldn't happen to have a picture of that bouquet would ya ?

Sad to say that the EMI101T-RC is now discontinued as well. Is there another replacement avaailable?
