Interesting.
Thanks for the test! And your nicknames are great! They stuck with me right away. So when you replied with RC and CS, I knew exactly what you were talking about without have to go back and reference the abbreviations. Nice work!
Strange… When was this?
And did you look for 350mA or 380mA?
Recently got 100 of these 350mA:

Look here for pics, also about sanding / filing down:
I did a driver mod. FET+1 modded to 19+1, totalling 20x 7135. Here’s the pics: [image] I’m just not a fan of direct drive, so the FET had to go. [image] Original plan was 12x or 14x 7135 for an Astrolux S3, but: [image] Inside a copper sheet 16mm circle 19 of them will fit. This will fit snugly in most pills for decent cooling (with some thermal goo). [image] Positioned them with grey epoxy before soldering them to the copper enclosure. [image] Added solder paste for …
I got these:
(some are from an other batch)
I ordered 100 packs from them on 1/31 and 2/7, both were Crappy Sailboats. All 350mA

Hmmm… i ordered them on January the 7th…
I don’t want Crappy Sailboats either…
Your pcb/ufo looks like it crash landed into your digital calipers trailing flaming led wires.
…so i search for ‘7135’ on AliExpress, and most of the pictures show the Raptor Claw chips…
I’ll bet sanding the bottom layer would drop the top chip enough for bent pins to actually make contact making the solder connection much easier on stacked set ups.
…but it seems “original Addtek” have the best reputation, they cost more too…
So what should i be looking for when i run out of Raptor Claws?
I’ll bet sanding the bottom layer would drop the top chip enough for bent pins to actually make contact making the solder connection much easier on stacked set ups.
Easiest way to stack (for me) is removing centre pin and super-glueing one (with pins bent down) on top of another.
Then you don’t have to worry about accidentally bridging pins and holding the 7135 in place.
Yes, there’s still that tiny gap, but that’s not a big problem.
It is for me. Having them touch so the solder clings easily to both would take care it. I’m glad you do it well though.
I just received my last order of 100pcs of these regulators and i got “Raptor Claws”. I ordered these April 8th from Fasttech. So it looks like it’s a little lottery for what you get.

Thanks for the update, i’ll put them back on my wishlist.
I found manufacturer of Crappy Sailbot. It’s Chinese company QX Micro Devices Co., LTD

If you want to buy original “raptor Claw”
Nanjing Micro One produces them
I got 1000 ordered on Aliexpress and it came as reel
found also this shop who sells them whith guranteed no fakes
MEL7135PG MICRONE(Nanjing Micro One Elec) US$0.1292 - SOT-89 LED Drivers ROHS datasheet, price, inventory C80214
they also produce known Lithium linear charger ships
The data sheet on that page speaks of MEL71XX, which suggests they make other values too besides the 350mA.
HEard similar rumours before, but never found anything.

Do you have a link or Aliexpress shop name, please ? TIA.
I got the 350mA “Raven’s claw” variety from FastTech over the summer. I have some 380mA versions from both FastTech and Mountain and both have the mark of the stupid sailboat.
