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...
Will shorting a lithium ion battery cause an explosion? Chain Reaction: The release of flammable gases can lead to a chain reaction, where the heat generated by the short circuit causes even m...
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...
Why can the channel capacity C of the additive white gaussion noise (AWGN) channel be denoted in different ways and how do they relate to each other? Examples: C = (1/2) * log2(1 + SNR) [bit?] ...
The other answers are excellent justification to the the industry standards imposed on CMOS logic. The historical migration to smaller lithography CMOS led to lower Cds values which led to faster ...
Adding to what Lundin said (+1): s is seconds, S is siemens (1/Ω). What we write here is inherently HTML. Greek characters like µ and Ω are defined as HTML entities, and can always be writte...
The spec 79V 0.5 ohm 5ms = 62.41 Joules . The TVS must be rated for a low temp. rise at this energy dump or higher. MOV's are limited by the number of discharges as the oxide wears out, but may be...
I've noticed there are a lot of tags referring to general physical quantities (e.g. current, voltage, frequency) I'm not sure if they are useful. For example, what usage would have the tag voltage...
One additional wrinkle not (at present) mentioned is that Class X and Class Y capacitors are used in those specific locations for safety reasons, having to do with the capacitors being connected di...
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’d like to create a stable IR LED light source. I’ve read that LED efficiency changes with temperature. I’ve seen two designs which used feedback through light to correct the LED temperature dri...
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.
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...
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 ...
Moderator Note If this site were mature, this question would be closed because it solicits opinions, or is too specific about particular models. In the interest of site activity, answers are being...
I have a MAX809 with RESET pin connected to the gate of IRLML6344. I will rephrase my question. At 5 V, RESET is also 5 V and the LED lights up. But if I add the fan, RESET drops to 0 V and draws 1...
Before we get into your problem, there are a few things to say about your descriptions. You need to step back and think about what we know and don't know, then learn to communicate specifications ...
