Re: tplink vr600 modem router - Capacitor
It's a solid capacitor , it's not matter what brand you must test it with a multimeter that has a capacitor test on it, out of circuit.but in my experience, i never replaced this type of capacitor and you may say what's the modem router problem ? -
Re: tplink vr600 modem router - Capacitor
why do you want to replace it fist place? Test it with an ESR meter.Comment

I read EBOOK of Testing Electronic Component and found that
"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."
Is it really possible to test small ceramic disc capacitor with analogue... -
I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm
And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,... -
Hi people, I hope this is the correct spot to post this, I'm new to the forum.
I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.
I hope these photos make it clear which component I am referring to:
(yes, the soldering is a bit botched from removing the blown one, I know)
I have found the board schematic (attached), but there does not seem to be a boardview available. I have never... -
Hi all,
It's gonna be a long intro, so please buckle in, as it's a problem that's been bugging me for several days now. Thanks in advance.
So, I have 2 modems/routers, whatever the proper nomenclature is, one from ISP and one mine. I want to power them via USB-C rather then their original mains adapters (for reasons, that are hard to explain to sane people). Both routers come with 12V/3A mains adapters.
For this purpose I acquired USB-C charger with 250W and 5 ports, 2 of which can supply max 20V/3A. Since 12V isn't a standard PD voltage option (and to future proof,... -
I've been writing a program in Java that is really just a robust front end for the use of GitHiub Gists, providing a nice interface for developers to organize, maintain and access code snippets that we tend to need from time to time in our different projects.
One of the features of the program is the ability for people to share their Gists with others who use the program over a LAN or over the Internet. The program just basically serializes a Java class and encrypts it then wraps it into a UDP datastream and sends it over to another user.
So I decided to implement UPNP...
