capacitor

Hello, the tachometer in my 1st gen 4runner suddenly died, and I pulled it open to look inside to see if it was damaged inside. Upon looking inside, I saw rust on some of the traces and what i believe is capacitor fluid on the chip and a capacitor. The chip doesn't have any visible damage except...

I have with me a tablet motherboard EM-H8811-178B to be specific. It developed a slight fault whereby the whole thing is confusing the Power Management IC is the AXP288C and the capacitors around it some show 0 on continuity others show low readings like 37,38 or 22 which should I remove or...

I’m developing a TPMS transmitter, and we initially used a chip antenna. It performed well in field tests and even had a reasonable transmission through a metal container. However, when I installed it on a truck, the transmission became terrible. After researching, I found that wire antennas...

Hi, I am an electronics noob. I have some questions regarding a particular application. I have to move a small cylindrical rod using a solenoid (whose capacity is 1.5kg lifting force and rated at 12V). My application requires me to energize the solenoid only when I get a signal from somewhere...

Hi all, Not sure this is the right place but Im looking for some expertise/help in understanding design of a simple circuit. Im looking to make something that would make a noise after being triggered by either impact or a magnet. Looking for this to be very very small also. Smaller than a...

I have an older laptop ASUS UX510UWK bought in January 2019. In about last 2 years I have random few seconds dropouts on my external 4K monitor connected over USB-C. I think the problem maybe be caused in the lifetime expiration of electrolytic capacitors on the laptop PCB. I think their...

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...
