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 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...
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...
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.
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...
If there are high slew rate signals or high-impedance circuits, layout matters. Otherwise, it usually doesn’t. Slew Rate (SR) in the time domain translates to bandwidth in the frequency domain, so...
I have a hat board that has some high power solid state switches (mosfets). The hat is controlled by the main board. The hat and the main board are connected via pin headers, like an arduino. Th...
I would suggest finding the root cause of all the noise and eliminate as much of it at the source. Baluns, active guarding, double shielding, buffering, current source control and matched impedanc...
Your current FIFO acts as a standard FIFO. What you desire is a First Word Fall Through (FWFT) FIFO or a showahead FIFO. Changing the rd_data to be combinational logic instead of registered logic i...
This looks like the block diagram was done by a technical writer, not the designer. It is someone's conceptual misunderstanding of a linear servo with feedback relays and optional FET drivers with...
The voltages from the raw microphone are quite small and fairly high impedance. That's why an amplifier at the mic is needed in the first place. The signal on the wire would be way too small comp...
Fault Codes (Page 38) PE ground is mandatory to be functional and is tested. Typical standards expect < 25 Ohms for residential zones. RCD's and similar testers use as test resistor to forc...
I changed value of resistor R318 from 10 kΩ to 1 kΩ, and that alone significantly improved off-time. From 200 μs to around 25 μs. That is much better. So I looked into datasheet again. I found t...
Some optos are really slow. What off time is yours specified for? Your circuit could be better. The transistor is turned on thru 1 kΩ, but off thru 11 kΩ. You are also giving it way more base c...
