I'm in the process of giving the tags page some structure, writing tag descriptions and creating synonyms and some hierarchy. I'd like to know the Community stance on a new tag I'd like to add: b...
I have here an acre-counter or crop counter device like the lykketronic shown below, using two AA batteries. It arrived without working. Upon opening its case, I found that the PCB is missing tw...
First, common mode is something that only applies to a differential signal. When a signal is encoded in the difference between two voltages, the common mode voltage is the average of the two. The...
what is the maximum DC voltage I can bias this connector at I don't see why this shouldn't be treated like any other component that has a maximum voltage stated in its data sheet or documentat...
They don't outright tell you the maximum operating voltage, probably because that would imply a power level beyond what they think anyone would use this connector with. Note that it is intended fo...
I've never been involved with the design of an ESD table, so I can only imagine some reasons to put grounding connections at the front: For convenience. If you've got a table specifically for ESD...
We have ESD tables in the laboratory with Earth Bonding Points: These are directly connected to PE (I measured). It is my understanding that equipment has to be connected to PE directly and ESD m...
If you're talking oscilloscopes, I used to do peak-to-peak measurements for the time period. And then, as you note, invert for the frequency.
I am currently learning amplifier design, after constructing the unity gain amplifier(which is a differential-input single-ended-output amplifier) in the unity-gain feedback configuration I have pe...
Hello,I want to simulate a delayed pulse going from 74ABT04 to the load which is UCC5304 where load with 400K i think. but my pulse source 74ABT04 is not an idial voltage source as shown in the s...
I would like to convert 5V rail I have on PCB to ±12V. Existing solution is using boost converter 5V to 12V, and a buck for 5V to -12V. This feels bulky for what it's needed - here are the requirem...
As of the early 2020s, common technology nodes for SSI (Small-Scale Integration) and MSI (Medium-Scale Integration) ICs include nodes such as 180nm, 130nm, 90nm, 65nm, 45nm, and 28nm. Each technolo...
CAN lines in the most common implementation have 60 Ω impedance between them. Anything that is substantially larger than that won't effect the lines much. I'd use 1 kΩ at least, preferably more. ...
Long-standing bugs ought to be fixed. I got another "500 server error" on an edit suggestion (this is far from the first time): 500 server error It's not your fault. This error has been logg...
I agree with Olin that unknown contact area is the biggest variable. I think the scientific way is to test and verify each contact using a 4 pin kelvin bridge. The sum of 2 pins carrying constant...
The 70.9/40.8 A rating for L.R. is rated only for ; Locked rotor time 19s (cold) 11s (hot) I doubt this meets your requirements unless you modify from a forced air cooling motor to a pumped liqu...
I got a vintage ('64) hifi sideboard for Christmas! It's super awesome. However, I don't understand the grounding. It has two female inputs on the backside that are labeled as "Grounding". There w...
If you choose suitable ultrabright LEDs , there is no need to use 40 mA. I have over 10 thousand LEDs all over 16,000 mcd at 20 mA which is painfully bright for close indicator but works well 100 ...
Remember that RMS measurements assume at least 1 cycle or in your case 100 ms or 10 Hz. So the Ripple Current/rms vs Temp rise is always valid for any duty cycle. This means in theory you can rai...
I've been experimenting with LC filter circuits on the output of a SMPS I recently bought because it was too high for the circuit I'm making. After hooking up many different combinations, I found t...
It is well known that it is difficult to filter the noise generated by switching power supplies, and this difficulty increases as the PSU is supposed to deliver large currents. For example, in a us...
While the terminology is similar to that of microcontrollers, and of CPUs in general, the "register" term here is specific to energy meters. Essentially, this board is a very basic version of a sma...
They aren't specific to the project, but to the MCU. As long as you use the same MCU for multiple projects, they will be code compatible. Some hardware peripherals are even code compatible between ...
I'm curious about FPGAs and would eventually like to get into them sometime during the future, so I'd like to ask three broad questions to help orient myself: In what applications are FPGAs the m...
First, that's an archaic chip that requires a lot of circuitry around it to do anything useful. Why use this particular chip? Second, the datasheet gives you an example of how to use this part as ...
