Unfortunately, I soldered everything in place before thinking about checking the output power, so no numbers from there, suffice to say that each LED was glowing as bright as if they were individually powered at a nominal 3. Vsat is very important. The vatasheet is supposed to be able to handle heaps of current as it is supposedly used in high frequency power amplification.

Would it provide any improvements over a common A? Positive ; Output Voltage Type: Delivery times 2sc vary, especially during peak periods. I know the circuit suggests 2N or 2N mainly because he was looking at only 1 LED maybe a maximum of 3so the current draw isn’t very high. Select a valid country. I definitely made a mistake somewhere.

Thank you for your suggestions. Will changing the core material, the wire thickness or the number of turns change the efficiency or output power? I suggest you look into salvaging this part from a disposable camera flash? The item is Cat No.

I did test it out on a simple satcure circut, but was disappointed with the output. It dxtasheet based on 2cs2500 circuit and this circuit. It’s just the inductor I’m dztasheet about.

Please enter a 2sc less than or equal to 2sc See all condition definitions — opens in a new window or tab Ships 2sc days, Delivery estimate: Note from the graphs that things are ‘falling rapidly off’ as currents go up and it sounds like you need to raise yoursyou need more ‘margin’ you need to be further away from the drop off.


That’s why it can have a common label. It’s a complex deal, having to do with the number of available carriers and the physical sizes of the parts of the transistor structure.

Should that be high or low? You didn’t make any mistakes I know of, the current through each string should be the same as the ‘base string’. Reviews from the Datasneet site English. First off, I’m not sure 2Ns are a good choice. And of course, the thickness of the winding wire will help, since thicker wire reduces resistance.

There seems to be a problem serving the request at this time. Sign up for newsletter. Add to Watch list Watching. I’m going to try and fix that and see what happens.

Actually tried this step during breadboarding and didn’t notice any change in brightness between 6 in series or 6 in parallel. I was given the impression that this was capable of handling much higher currents, that is why I’m using them.

Another Mod regulated SatCure circuit Photos of the mod can be found here. That’s about as small as I can resolve with 2sc2050 aging, diabetic eyes ‘o mine. I think running the original bulb would have been as efficient. Another Mod regulated SatCure circuit Doug: And also I’m guessing a high Ic should be good too? Minimum Current Transfer Ratio: Thread Tools Show Printable Version.

I enjoy playing around with things like this circut to see if I can get a little better performance out of it a leftover from my days as a mechanic while in college, I’m sure.


Doug mentioned that it should be the lowest F number you can find. But I do wonder 2s2500 the balance of this. Another Mod regulated SatCure circuit Doug, thank you so much for your help. As we go to higher and higher voltages, this ‘extra’ needs to be a larger and larger percentage of the total, further increasing the need for yet more power.

At the kinds of Ic you’re running they’re running out of gain rapidly, keeping them saturating as they heat up you’re on the wrong side of the curve already could be problematical. Datzsheet shipping on first 0. I’ve made the fix. I tried running a SPICE simulation for the circuit I actually built as oppposed to the circuits shown on the 2 websites but according to the simulation, the LEDs shouldn’t light up or should have blown up already.

2SC (Toshiba) – Transistor (strobe Flash, Medium Power Amplifier Applications)

Front Page What’s New? Notice that one of the authors of the sites you point to discusses how important this is and suggests a source for the special sort of transistor you want, camera flash circuits.

But who do I think I am, Peter from Arc? BTW, with two transistors and plain old RF chokes, much easier than hand winding ferrite beads but prob. I wouldn’t worry about Vbe, it’s Vce we need to get as low as possible. Another Mod regulated SatCure circuit I recently datashdet another mod.
