Nichicon HM/HN/HZ scheduled for discontinuation

Re: Nichicon HM/HN/HZ scheduled for discontinuation

At my, now, previous employer I compared HD with HE for a very different usage than what folks here do. I was not impressed. Then again, I was subjecting the things to 7X-10X (not a typo!) the rated ripple current, not anything like P/S or VRM usage. Generally, Nichicon PW, PA & HE, Panasonic FC & FM, Rubycon ZL, and UCC LXZ and KZE series did best in my torture test. That was over 3 years ago, BTW.

Did anything blowup in your torture test? And how did you torture them?

Its a shame that they are discontinuing them.

No, HV is miniaturized HD ...

M would be MEGA (one million) ... m would be milli

milli - a thousand

it's subdivisions of SI units ... 1 meter = 10 decimeters = 100 centimeters = 1000 millimeters

1 inch = ~ 2.54 cm

Re: Nichicon HM/HN/HZ scheduled for discontinuation

lots of power supplies have > 16V caps, and most polys have really low capacitance at such high voltages. This can throw things off on power supply type circuits

we don't have to find a certain brand series, just any series that is equivalent in specs (and reliability). This is why i'm making the cap database. zeerrrg let me ask you guys a question, is M ohm ohms / 100 or 1000

Re: Nichicon HM/HN/HZ scheduled for discontinuation

One option might be to insert a current sense resistor in series with the cap to compensate for the lower ESR when recapping with poly caps.

I think I might could understand where Nichicon is coming from on their decision to discontinue the series in question... I can only wonder about sales figures... I think that most newer mobos nowadays are being designed with poly caps... there might not be enough demand for those series to justify taking the time and effort to continue doing production runs for them.

By the way, the table says you replaced the 220uF 16V RLS on the -12V with 330uF 6.3V SEPs.

No. Not unless you modify the feedback loop

Re: Nichicon HM/HN/HZ scheduled for discontinuation

Could poly-modding power supplies be routine practice too?

Re: Nichicon HM/HN/HZ scheduled for discontinuation

So poly-modding motherboards will become routine practice. Right?

Re: Nichicon HM/HN/HZ scheduled for discontinuation

That is all sad news indeed .

Time to really start hoarding

Indeed.
I have a good source of used Nichicon HN and HZ in only a few certain sizes, as well as MCZ. Time to heat up the iron and start pulling them.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

Shoot, they're a step higher in ESR than HM. :/

This looks like short-sighted management at Nichicon.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

The thing that strikes me as odd - not questioning the basic news story - is that I don't see a replacement for these series. Is the HV series as good or better? If not, are some news series about to be rolled out? Or have they come to the conclusion that these series are too finicky to manufacture with consistent quality? Is Nichicon's lunch being eaten by cheap crap combined with short-sighted customer decisions? I'm just trying to figure out what Nichicon is doing in business strategy.

Looks like we may have to use HD. HD seems fine for motherboards.
My Asus A7N266-VM has HDs along with HMs. It has HDs next to the DIMM slots.

Looks like Nichicon is trying to shove us to HD. :/

Re: Nichicon HM/HN/HZ scheduled for discontinuation

No, HV is miniaturized HD, so it's equivalent to Panasonic FR series. And I don't think I've ever seen it stocked anywhere...

Re: Nichicon HM/HN/HZ scheduled for discontinuation

did I do good master? did I do good??

heh really I wish I would of brought it to your attention earlier but while I was going adding nichis to the database and trying to figure out which ones were already schedule to be discontuned I discovered that disturbing little fact

now all we have to do is hoard. Perhaps you should contract with rubycon to make badcaps brand capacitors! No wait, putting 'badcaps' on a capacitor might not be a good idea

Yup...I guess that's that. Time to really start hoarding, they haven't stopped accepting new orders.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

People don't buy PCs anymore... When they do, it's either bottom of the barrel stuff they would never get repaired, or really high end stuff that uses good polymers. We'll have to rely on shady Chinese new old stock. I think Samxon stopped making GC/GD a long time ago. And HZ was the only capacitor of its class in production.

The frenzy of fanaticism for polymers also caused this... There's only a few good polymer makers out there, but the plethora of inferior polymer manufacturers have contributed to this... The difference with inferior polymers and inferior electrolytics is that inferior polymers don't usually bloat. Asus and kin will now be able to get away with selling junk.

You have to admit though, they have good reason to discontinue it. I've wondered myself who is actually buying new stock besides ourselves.

Re: Nichicon HM/HN/HZ scheduled for discontinuation

I have heard rumbles about this from a couple unofficial sources, but nothing 'straight from the horses mouth' so-to-speak....but I am stocking up just incase....
