It is basic electronics knowledge. I’ll disagree with Andy about your filtering.

I don’t know what I’m doing – this is a learning experience. Same for D0, not needed.

Trey Carpenter 6 2. The transsitor may be the seller’s own price elsewhere or another seller’s price. No ratings or reviews yet. Use the other one. Maybe the LEDs themselves are better protected internally and this saves the day as you believe but I cannot check this as I don’t have a data sheet or part number I’m not going to follow ebay links transistoe – if it aint got a data sheet pdf I wouldn’t buy it!

What you need to learn first cannot be explained here in a few lines. I believe that your cap is adequate. Any Condition Any Condition. The “off” amount and percentage traansistor signifies the calculated difference between the seller-provided price for the item elsewhere and the seller’s price on eBay.

Below is a simplified schematic. Ok, first of all thank you for your feedback. Are you sure you know what you’re doing? But do take power dissipation into account. You are measuring the average Vce in v3866 presence of the PWM, and you should expect that to be much higher than Vce on.

Furthermore, the Vbe will be about 0. We will do our best to get back to you as soon as possible.

Your problem is much more fundamental to your design. Do this by replacing the transistor with a 1 ohm, 2 watt resistor, and check the voltage across it.

Please educate yourself first before proceeding. Be able to make power calculations etc. Essentially I know the circuit works. Show More Show Less. However, since you seem to be having heat problems, I’ll assume that your transistor is not being properly driven. Sign up using Facebook.


The lowest-priced brand-new, unused, unopened, undamaged item in its original packaging where packaging is applicable. Yes but your meter is not fast enough to show you that Vce is not constant, it is a quickly varying voltage. 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. Your LED current is unlimited, no wonder they burn out.

Note that hfe is the same as beta. WhatRoughBeast 49k c38666 28 This item doesn’t belong on this page. Ground at bottom right: You must choose at what current you want to operate them, make an estimate of the voltage usually around 2. Andy aka k 10 Email Required, but never shown.
