capacitor

Would like to make a simple car side-mirror simulator circuit. The side mirrors I installed (for better blind spot) do not have a dimmer circuit and I am getting LIN bus errors since the dimmer wires are disconnected. Would like to DIY something that fools the car into thinking it is...

Hi All, This is probably a very easy question, but if I have a 3.7v lipo battery attached to a voltage regulator outputting 3v, and I have a 100nF filtering capacitor to filter out noise, should I put the capacitor before or after the voltage regulator. Also, would I just want the voltage...

I put the 1nF capacitor for ESD protection in the LIN interface node. After testing 6kV, impedance deterioration before and after was measured in the measurements. Does this mean that insufficient capacitance values are likely to be applied?

Hi all, I have this IC which creates a linear voltage ramp proportional to the input voltage based on the capacitor on the output in parallel to ground. I then have to do some analog computation using op amps. When I connect the output of this IC to an op-amp, the ramp is ruined. Is there any...

Hi everybody, I'm taking a beginners DC circuitry course and I'm trying to learn on my own time about analog circuitry, something which has fascinated me for a while now. One of the things I'm trying to start with is, as the title states, a voltage follower, since this is (supposed to be) a...

Hi, I am trying to make a simple fm tuner as per the circuit diagram attached. Problem is, BF494 transistors are not readily available in my locality. Hence, I have used 2N3904 transistors as an alternative choice but the tuner doesn't seems to work. Can this transistor be used in this circuit?

Can anybody tell me what type capacitor isthis?Is it polyproplyne ,polyester or ceramic? Is it good for audio coupling?

Hello All, How I can choose right Capacitor for EFT burst on Supply line or I/O Port, it is related to clamping voltage, Peak current, time of Burst. it will helpful me and others also, Thank You

YouTube video with the sound What is this sound, and why does it happen? After discharging the motherboard (turning it on without a power source), and then powering it with a battery, it makes that high pitched noise (before the buzzer beep). Is it the capacitors charging? It makes the same...

Hi all, I got a Delta 50-761 dust collector second hand and it has been giving me trouble. It turns on, fan runs, but it blows the start capacitor within seconds. I replaced the capacitor and it did it again. I looked at the centrifugal switch, thinking it might not be functioning and causing...

Hello, My battery powered hair clipper has not enough power for my purposes. Therefore, I decided to remove the battery in order to get a larger DC Motor in it. I have already made a modification of the case and installed the new DC motor properly. Here are some stats of the new DC Motor...

Hello! First of all, I'm sorry for the bad English, I'm using Google Translate for most of the text. I'm doing an internship at university in an electronics lab and I've been asked to print a capacitor using a Protomat E33, however, it's my first time using such a machine, I'm not sure I'm...

Hello, I am a farmer not an electrical engineer, but I have recently been trying to learn more about the electronics we use in farming. I have been trying to troubleshoot the grain loss system on our combine that hasn't worked in years. Keeping in mind that I am a farmer, as I understand it the...

Recently,i snnaped ,a capacitor,from my motherboard supermicro x9dae...im a newbee on things related to circuits...i try to find the capacitor online for replacement...but is so confusing for me...if anybody can read my post,maybe can guide me to find ,or a link where to find it...many thanks..i...

Hello I made a circuit that turns on/off the fan according to the temperature and controls the FAN speed(PWM) and this is my PCB design this is 2 layer board and both GND plane the FAN Speed Control motor is 3A and the Comp FAN motor requires 4 A power before this circuit, there was no...

Hi Ladies / Gents - I am trying to understand this concept a little better. C = I / (2 x f x Vpp) "Vpp = the minimum ripple (the peak to peak voltage after smoothing) that may be allowable or OK for the user, because practically it's never feasible to make this zero, as that would demand an...

Hi All, I have a issue I am trying to resolve. I am using a timed output relay (Redarc TIM05) as a kill switch. Once a momentary button is pushed, an output is set at 30 seconds, supplying 12v to pin 86 of a 30amp relay that runs inline with the starter motor trigger. The issue I am having, is...

Hello everyone, i am new here and i don't have any education about electronics. I have just learnt very basic things from internet and by breaking, modifying and damaging electronics..!! I have done assembling computers and repairing motorcycles.. i love fiddling with electronics.. Anyways...

Hi, I do understand that the C5, L3, C6 form a pi filter. But what is the purpose of the other capacitors i.e C8 and C7? What purpose do they serve?

Me and my friends have been building a project for a couple of months now and we got stuck on on something we dont have much experience with. We need to connect 4 charged capacitors into series in order to have a higher voltage than the supply, we have been using relays and a arduino nano to do...
