ptn4050 parts list double check

[Cvilledustin]

hi guys, building a list for the parts i need following breaktru .44 boost mod. got me the ptn 4050 coming already. heres the parts i looked up, just double check me make sure thats what i need

100k trimmer
Invalid Request

100uf tantalum cap
Invalid Request

still need to find the resistors but what do you guys think? correct or wayyyyyyy off?

Well. Just noticed. My links are no good

the links are good

So far so good. I believe 16v minimum is recommended for caps, but 10 should do. Some argue that you don't need any for a vaping application, but some is better than none.

Break tested without and said it gives a longer vaping time with. I may have that post confused with the 08100 tho but yeah he said he noticed a longer vape on same batts with caps.. I use caps on mine hits up to 37 watts (may go higher) with a lipo liion capable battery hugely underated on data sheet or on borrowed time. Using it everyday @24watts.

Love this mod.. Boosters so hard to find happy theres one that is awesome for us modders.
Heres a great addition for it. I am considering adding to a 4050 box mod
like Mamu's passthru with omnitester.

I just checked and the caps should be rated higher than twice your output voltage , so 10v is good for under 5v output and 16v caps to 8v output. Page 10 of the datasheet has recommended caps, including Kemets, just not those.

I fully agree with Visus about these boards, just got some more today along with a 8100. For myself the best feature is the small size as it allows much more compact builds. I personally prefer to forgo VV and set the voltage to 4.43 with a fixed resistor and just vary my coils. The 8100 gets the same treatment and is set to 4.6v for an even smaller build.

asdaq did ya know they fit with the pcb pins removed inside an ego. I was gonna make a mod out an old 1100 twist with a 650 mah batt and 4050 but have breaks aa box 1200mah round madness lol.. Soon lol maybe a year or two but its parts are put together and aside..

Good find asdaq about the caps. I'll up it to a higher one. Board should be here tomorrow so need to find the other goodies for it soon

I guess I could just make it easy on myself and grab one of the 100uf caps the data sheet says too. Lol

Visus a 1100 mAh twist sounds loooong. I don't recall the ID but I get it into a 15.1mm OD brass tube that has a thicker wall than the SS of an eGo, with caps and resistors and LED and a PTC fuse. It sounds like a similar fit to the ego tube. The 4050 can be pushed past its limits, but they dont last as long, on ones that have failed it seems to always be one of those SMD resistors has cooked, if I can find a cause...

I look forward to getting some VTC4's and purple efests to push these two chips, soon, soon. Right now I'm using red efests acquired last summer.

Cville, grab TWO.

You can also use low ESR Aluminum Electrolytic capacitors as long as they are no less than 17 milliOhm (ESR). 10V or higher caps are fine. The datasheet shows some at 6.3V which I have also used.

So I stopped by my local RadioShack to try and minimize the stuff im ordering and give me something to do today they had these

But they seem kinda big really. Maybe it was just me
