Classic DeltaPulse in new SMD revision

[StarShina]

My personal version. It designed for installation in a small enclosure Gainta G706 and has a PCB size of 10 by 10 cm.

Interesting work thanks a lot for your effort.hopefully the pcb works fine.

StarShina
can you provide pcb file of your project? .

[kt315]

sorry, but my board has the follow features:

1. tantalums on power lines,
2. fastest reset/mod on turn on.

The PCB from kt315 is very excellent quality

What are the advantages of tantalums in DC power supply circuits other than increasing the cost of the final product and the risk of catching fire when the power is increased?

[StarShina]

I think not good tracing of power lines, isn't it?
Do you perform PDN analysis of PCB?

why i have to teach you here by electronics basic course??? yourself. just yourself.
i'm not the Phd of Preston University to teach you.
all my projects are done from garbage. NO need to buy nothing, no increasing the cost.
we call that TRASH TECHNOLOGY, here the link https://www.geotech1.com/forums/show...ash-technology

I would also recommend that you don't get nervous.
You were just asked, what do you see as the advantage of using more expensive tantalum capacitors over cheaper aluminum ones,
if low ESR and low leakage current is not required?
No need to teach anyone, you just need to answer what is the feature?

of using more expensive tantalum capacitors

expensive??? i am taken kilogramms of them from PC boards, HD boards, DVD boards etc. just your fantasy.
DP is doing from trash electronics. but some reserves of CMOS ended, so i bought some on ali with just
aim to give to people links on honest chinese sellers, with 'good tested chips' because they ask.
ask PCs' manufacturers why they set the tantalums on the boards LOL!

Do not find the situation are stupid, I ask you what is actually the feature of replacing electrolytes
in the Delta Pulse metal detector with tantalum and you send me to ask the manufacturers of PCBs?
I smile.
