LV2000 vs LV2021 vs LV6100

I thought the general rule of thumb was that tantalums were 'bad'...

Wizard of Wor sound amp fire!

Hi, I am setting up a Wizard of Wor piece by piece. Today the time had come for plugging in the sound amp. Tested the speakers in advance with the good old 9v battery trick, and I was ready to go. Plugged it in, and BAM! The tantalum cap at C1 lit up like a christmas tree! It split right in...

Old TANTS - bad.
New TANTS - not so bad.

Other cap technologies are more tolerant to aging, over-voltage, high ripple, temperature variations and physical abuse, etc.

I like tants because it's easy to tell when they've gone bad.
Seriously though, they do have their place.

They have an equivalent series resistance (ESR) ten times smaller than the ESR of aluminum electrolytic capacitors, which allows for larger currents to pass through the capacitor with less heat generated. Tantalum capacitors are very stable over time and their capacitance doesn't change with age significantly, especially when compared to aluminum electrolytic capacitors. They are very reliable when handled properly and their shelf life is virtually unlimited.

And what about when NOT handled properly?

It's hilarious that despite your talent with electronics, you're unable to tell when I'm baiting you to explain something for the sake of others here.

Well it's pretty fucking clear you're not going to explain anything technical yourself, and you certainly don't have the class or integrity to tell others I'm correct.

And I read the fucking datasheet years ago, dipshit. That's where I noticed the stock design for a regulated dual supply is oddly similar to your LV6100:


Now tell me again about original ideas, and how copying is bad.

What the fuck do you think datasheets and the reference designs in them are are for, assclown?

"Oh no! You designed a circuit the way the manufacturer said it should be designed!"

Maybe you should try actually designing something...

Such a delightful person. I'm surprised Peter was willing to work this person on these. At least that's what spath is insinuating, but it may just be his classic god complex of how he has created everything.

Just another example of how not every design problem has a solution...

Ok, I thought we'd reached peak self-unawareness. But apparently I was wrong.

You criticizing anyone about class or integrity is painfully hilarious. Are you really THAT blind to your own behavior?

Practice what you preach, twinkie.

PS - I explain plenty of technical things here, you're only exposing how little of the forum you read. Maybe try more of that, instead of playing guessing games with PCB's you design that nobody will ever see, for the sole purpose of stroking your own ego.

"Oh no! You designed a circuit the way the manufacturer said it should be designed!"

So when you copy something, it's not copying.

Got it.

It's cute that you think your posts are technical

Got it.

So what you're saying is no circuit should be designed the way the manufacturer intended.
#Got It.

Clown.

Reference designs LITERALLY say "copy this or we won't guarantee it'll work". Many datasheets even include PCB layouts these days.

Funny though -- none of my products have come with documentation saying "copy this and sell it" -- not that you're able to understand the difference.

Tantalums don't react well to overvoltage or reverse polarity.

Neither do electrolytics, and electrolytics have garbage high frequency performance.

For SMD, there are now bulk (or MLCC) ceramic caps that have high enough capacitance to replace tantalums, but I've never seen such caps packed for through-hole applications.

It's cute that you think your posts are technical

And it's cute that you think your posts help people fix things.

 

[tron guy]

you can pm each other just as easily as posting out here. (it is an option)

Then I could waste my time reading other stuff.
