capacitor

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 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...

Hello, I have a guitar wireless (shouldn't matter) and it seems that a capacitor has burned out (picture included). But I am not even 100% sure this is a capacitor, the markings do not look like anything I've seen. The good news is that the PCB has several other devices that appear to be the...

What is this .1k in nf on this polyester capacitor?

Any idea what could be the issue or wrong with it?

Hello, I have a schematic in a pdf format (generated by Altium Designer) which has the below capacitors labeled LEC692. My first guess was this must be the Part Number but I didn't find it in the "Miscellaneous devices" library!! And also looking into the internet didn't give anything!! Can...

Ok so I have a twin tub mini washer and I need to replace the capacitor because the washing motor has stopped functuooning. This machine has a round dual capacitor for the spin dry motor (which is still functioning fine) & for the washing motor which runs on high or low speed. It has four wires...

Setup: MPLAB Mindi Simulator in SIMPLIS mode, *.mod model file of capacitor GRM31CC80G227ME11. I have loaded(via model library addition or directly including using .INC file) a Sub circuit model of Capacitor(GRM31CC80G227ME11) to Generic capacitor part in Mindi Simulator and using it circuit...

I have watched recently this video: At the end of it he describe a way to make edge detector by using capacitor and resistor. The thing is i don't see it being discharged in any way. Would't it make it impossible to charge again and in consequence make current flow through the resistor and make...

Hi, I have a question to solve. Why should an starting capacitor only be used in single-phase motors and not in devices non-motorized, for example, a television? The starting capacitor protects the motor, I would like to know if the starting capacitor is equally useful in protecting devices such...

Hello, I have been making circuits as a hobby for 2 years now mainly focusing on trying to make a coil gun, and tried and failed 7 times now, and I am in desperate need of help with the circuit, if you see anything wrong with my diagram please respond as soon as possible. I bought most of the...

This is the cap(the one on the left) on the power board of my monitor. 4700uf 25V. Since the monitor turns off in a few seconds everytime I power it up I tried to take a look. Since it is not egregiously bloating I was wondering when do caps like these stop working or is it already a goner?

hello everyone. i´m doing a voltage source and i want to get approximately 30V-500mA on Vout with the smallest ripple as possible. : i got a transformer 12 0 12 V and a 1000V 2A bridge rectifier and 4700uf 35V electrolytic capacitor. The thing is: after rectifying it it should give me 24 *...

Howdy, It's my first post here, I've been trying to work the issue out myself, but where I'm at currently I've no functioning RDA protection on the mains breaker and I've no sacrificial fuse equipped power bar to plug my project into in case it causes a surge I'm trying to fix my grandma's old...

So I have designed a relay that automatically switch to battery source input if blackout happens, to power my 12V wifi. But the relay has 1 second delay to switch to battery input. Many people suggest me to get a capacitor, to buy time waiting relay to switch. Question is : how much uf...
