Tantalum caps are tiny party grenades. :party:
By which you mean they work great in low voltage scenarios like this? :face_with_monocle:
Seriously though, what exactly are you implying?
Well, those should be fine here. Just triple check polarity and de-rate the marked voltage 33%. They are notorious for exploding and flaming, plus they often fail shorted, so I always think of how fun they can be in some places. Personally, when possible, I avoid them.

Makes sense.
Ceramics use to be more limited in uF or larger in size for an equal uF but they’ve improved, less need for tantalum now. And no polarity to care about.
Sorry for the OT. Simon, you say that your version of the LD25 is 3000mA, 700mA and 80mA yet your aliexpress store says modes are 100, 40(1200mA) and 6% (180mA). Please update your store information.
convoy-flashlight:no ,not this version ,the mode of LD25 in my stock is different ,
it’s
Lo (80mA) > Mid (700mA) > Hi (3000mA);
Double half-press: StrobeThis LD25 or another? This one has two groups. Do you have LD25 with 4 groups/stars?

sorry ,there is no star version LD25

I have two version LD25
sorry ,there is no star version LD25
Thanks for clarifying!
Did you ever carry/make a Nanjg 7135 driver that had moonlight low (I think it was 5mA mode) as well as H-M-L? I am trying to find a driver like this but can only find old discussions of it.

Are you not referring to the Qlite from IOS?

I'm not sure if these are low enough for you but are four modes. Supposedly .03 amp on low.

:_( I notice that Ric did not bother posting 17mm pictures, both listings show the 20mm version. Do you have these? If so will you measure the spring for me? Mostly I’m interested in what diameter it is where it sits on the PCB.
Can do but you will have to remind me when I get home from work in 9 hours as I will forget.
Sure! If I had 9hr of work I’d forget where to go home to.

Yes, that was it. I don’t think they sell them anymore. I do have an Atmel programmer somewhere but it’s just easier to buy a new driver.

Thank you for the links! I didn’t know about these.

AFAIK IOS and MTN both carry them.
$4.7 seems a bit expensive!

Plus it has two medium modes. >.< Reflashing looks like the way to go.

IOS has them listed, but I have been getting them from Mountain Electronics.

if you usually use the moolight mode ,i think LD25 driver is better ,LD25 has no pwm
and of course ,i can make moonlight mode version 7135 driver
