The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. Furthermore, the Vbe will be about 0.

What you need to learn first cannot be explained here in a few lines. LEDs have a very sharp voltage-current relation. OK, some comments on your new schematic: Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.

I believe that your cap is adequate. Post as a guest Name. Take a look at this: You think you control Vce by changing R2 but you’re not.

2SC3866-2SC 3866-C3866 TRANSISTOR-N 900V 3A 40W

The only hold-up is that I have tried two different NPN transistors salvaged from old CRTs and both end up with Vce voltages around 35V causing them to cc3866 up rather quickly since the current is around 1 amp. Andy’s circuit has an inductor but that is because the IC that is used there is a switching converter with current feedback. You have nothing of that sort.

You must choose at what current you want to operate them, make an estimate of the voltage usually around 2. Essentially I know the circuit works. Be able to make power calculations etc.

You still do not have the required current limiting for the LEDs in place, you added L1 but it is useless here. Best Selling in Transistors See all.

So the resistor should be about 10 ohms. See details for additional description. Save on Transistors Trending price is based on prices over last 90 days.

I’ll disagree with Andy about your filtering.

Below is a simplified schematic. Actually, from the transsistor sheet, at 1 amp collector current, a mA base drive will only drop your Vce to 5 volts using the C, so I don’t recommend using it. The rule of thumb is that, when a transistor is in saturation, it has a gain of about 10 to The price may be the seller’s own price elsewhere or another seller’s price.

Let us fix the problem for you. Foremost, the inductor and feedback diode seem like 3c866 very good idea. I have considered and addressed your comment in the one above. Ground at bottom right: Second, I probably should have indicated that I am used 9x 10W 12V LEDs which I did a few tests on before hand to obtain a general range of internal resistance.

Sign up using Email and Password. You must not treat a string of LEDs as having a resistance! No ratings or reviews yet. I have been working on a high-powered LED light bar. You need to keep in mind that, with a 5 volt supply, a putting out. Home Questions Tags Users Unanswered. I have measured the output of the timer at 2V RMS and set the resistor values for each transistor according to their Ib vs Vce graphs around 0. Are you sure you know what you’re doing?

Ok, first of all thank you for your feedback. Email Required, but never shown. Yes but your meter is not fast enough to show you that Vce is not constant, it is a quickly varying voltage.

If you don’t know what I’m talking about, then look it c386 and study it. If the voltage is more than 1 volt, you know you’re trying to pull more than an amp.
