Just to repeat KlausST's comment about using capacitors as an ESD protection: It is indeed a well-working solution, if the capacitance is sufficient. The easy way of estimating the theoretical maximum voltage is indeed considering the charge transferred. I am using myself the equation Voltage...
The relative humidity plays a large role on conductivity of wood-based construction materials. Therefore it varies greatly, and is not considered an ESD solution. Sometimes it is even too conductive, other times it is just too dry to conduct well enough. All depends on air humidity and other...
As I don't know the format of data (the model) you want to import, I can give you only a general advise and a link to a much wiser guy that what I am:
- It is possible to import "foreign" spice models to LT Spice. However, sometimes I have seen incompatibilities between the definitions in the...
If that component is connected to the tuning dial it is more likely a variable capacitor. Unfortunately the pictures don't show the part too well to be 100% sure. However, nearly all mechanical tuning devices in radios are variable capacitors, especially for AM.
Btw. what is the purpose of the...
LiPo and LiIon batteries are very picky about charging and discharging rules. Also, for instance excessive overcharging not only destroys the battery, but it can lead to catastrophic failure (in other words, an explosion or fire). Similar risk is in case of large over-current (or outright short...
To fully understand potential complications with flip-flops one has to have some understanding how they are constructed: They have usually multiple "latches" (simple bi-stable loops with feedback, usually drawn as two NAND gates with crossing feedbacks)
A typical edge-triggered flip-flop is...
Frankly, I think there might be a mistake in the book, as usually on a data sheet we find MINIMUM hold time - meaning how long the data has to be stable after the active clock edge. Also , usually the MAXIMUM propagation-delay time is specified.
Interchanging the two terms makes at least more...
Have you used the "soft start" feature? Without it, switching on the TPS61500 will generate a very large current spike. Also, as schmitt trigger already pointed out, this kind of chip works best on the 12V supply, and you avoid a lot of trouble when you move it away from the 5V regulator output...
As a matter of fact, by eliminating the receiver termination, you would get 50% of the driver's open circuit voltage in the receiver end, without any problems. That configuration is called "series termination", and there the driver side is terminated correctly. Usually one uses a low-impedance...
If you google "color coded inductors", you get some ideas and can find even calculators converting colors to values.
I have seen some similar inductors before, and if this one is "as it used to be", here the value-defining colors are brown+black+red. That reads 1 0 00 . The tolerance ring is...
Unfortunately your question is impossible to answer, as it is presented. You see, an optocoupler is a component, which usually requires some more circuitry around to do anything specific.
Therefore, would you please tell a bit more what you want to achieve? Analog or digital interface...
If you don't fully trust the internal protection of your micro-controller, you may use two diodes in series, as illustrated here.
The trick is to use low-leakage diode(s), one I have utilized is that SMD dual diode in the schematics
I would analyze some of the failing units: Even if potted, there should be a possibility to "dig in" where the battery is, and then substitute the battery with a power supply and a current meter. That should give an answer if the battery is self-discharging rapidly due to a production problem or...
It is difficult to be sure based on only a photo, but I can't at least see any laser driving output in the picture.
A couple of notes about driving lasers, especially powerful ones: It is NOT trivial, as lasers are inherently difficult to drive. And there are many types of lasers, from laser...
As Betwix pointed out, the phase is always relative. For instance phase of output of an amplifier is expressed relative to the input.
To define a phase in degrees, one has to have a repetitive signal, which then has also a frequency of repetition. As our time goes only forward, the output is...
