There's lots of specialized tools for various through-hole components overall, all of them generally called "lead benders". For TO-220 it appears that the term is lead bending/forming pliers. And t...
On paper you can measure the input impedance of an amplifier circuit by attaching a voltage source to the input, shorting the output, and calculating the resulting impedance from the voltage and cu...
A different type of solder, other than using lead-based solder, is probably not going to help. There are two causes to your problem: Crappy tips. Higher temperature required due to lead-free sol...
After some research I found some reasoning behind the voltage range: 1500V is sufficient to destroy the somatic nervous system, which is responsible for consciousness and feeling of pain. After ap...
Catching a flyback pulse is actually a rather easy application for a diode. Many of the diode parameters don't matter much. The basics are: Reverse voltage. This is simply the maximum voltage t...
The Codidact team has recently informed us that it is now possible to have different rep bumps on different post types. See this new answer by Monica to the old meta discussion that created the Pa...
It is common to have a series resistor to limit the current trough an LED. I saw a circuit using the LED driver: stp16cpc26. but instead having the series resistor, they are in parallel. This LED...
I see a lot of common collector amplifiers with the output taken across an emitter resistor. What is the purpose of doing it this way instead of connecting your load directly to the emitter? I sh...
Are BOM/PCB assembly cost cost optimization questions on-topic here? I can see how chasing down specific parts, prices and vendors ought to be off-topic, so I don't mean outright shopping/second so...
1 - Signal 2 - GND 3 - PWR 4 - Signal This seems to be common advice, especially on the 'net someplace, but that doesn't make it good. Stop and actually think about what problem you are trying to s...
Roughly around 27 MHz is the old "CB" (Citizen's Band, 11 meter) frequency block. The advantage of this band is that it is free to use with limited power. This is the band "walkie talkies" used t...
Just to let you know: if one day you have to use the LM337 negative voltage regulator, protect everything with TVS or Zeners. This is the most failing component I've ever seen (and I'm not the only...
You haven't provided any context, so there is little to say about this particular design. For all we know from what you told us, this could be homework from a student that just made a mistake. How...
I always had trouble understanding the terms "digital" and "analog" A digital signal is intended to indicate one of a finite set of discrete states. The number of discrete states is usually two fo...
When soldering Micro-USB or USB-C connectors by hand, flux is applied generously. This sometimes results in flux getting inside the connector housing, making it sticky and creating high physical re...
Direct answer How to clean off flux depends on what type of flux was used. Most electronic parts can handle being washed in clean water. In fact, boards often go thru what amounts to an industri...
You are forgetting that the transmitter plays part of it too. ACK is dominant simply because the transmitter sends ACK as recessive and any receiver must be able to override the recessive state of ...
Don't put the "protective" series resistor: connect directly your regulated power supply to the diode (with a short wire) and measure the current: the voltage regulator is all what you need to prot...
Allow me to address the MOSFET only as a source follower. this has very unpredictable linear use without voltage = current feedback as the RdsOn at threshold has a wide tolerance.(>20%) (Many...
I have boycotted the SE and neither asked or answered any questions so am happy to have a new home here. I'm glad you're here. You might also want to mention this in your SE profile, and point pe...
"Also, if there is a way to control this drop (without using an oamp), what are the design rules, or perhaps the rules of thumbs ?" "I reformulate this question:do you see any reason to use a FET ...
FET source-followers are generally less predictable than BJT (bipolar junction transistor, like NPN or PNP) emitter-followers. An emitter follower output is one diode drop below the input. The vo...
[I’m asking this question out of curiosity. I understand that this aspect of the CAN bus specification is what it is, and can not change.] The ACK bit in any CAN data frame is dominant. Each rece...
I'm curious about the market trend of certain kind of components (specifically, 0603 ceramic capacitors) and if I should start worrying about these getting phased out. I started to write a question...
