For an ideal current source and an ideal capacitor, there is indeed no DC steady state. … But in practice the source impedance is finite, and the capacitor will have some leakage resistance in parallel. So the voltage will be limited by that. …

Both don't offer large capacitances, so this is often one spot where capacitor compromises have to be made. Edit: I always mention class II and class III ceramics together. …

Diameter of 3 mm, height of 5.3mm. But you could also just look at the footprint. If your desired dimensions are not in the library, then you have to draw a footprint yourself.

If there is at least some series resistance in Vin: measure the series resistance by a DC resistance measurement between B+ and B-. Short B+ to GND and measure Z(f) between B- and GND -> Calculate C …

The capacitance formed between copper planes in different board layers is typically much smaller than the capacitance from discrete capacitors. but it has a very low parasitic series inductance and th …

According to the Arrhenius law, capacitor 2 will be the longest-lived with about 20 khrs at 85°C or 1280 khrs at 25°C. …

It is typical for device in floating scenarios to acquire high voltages and subsequently get destroyed when they are grounded. It can be even enough to bring them in contact with another floating, but …

It seems possible to "abuse" a X2Y cap as a feedthrough cap: namely by passing the line through its two transverse pads and attaching GND to the two capacitor pads. Has anyone done/tested this? …

Wrapping your value with {} will allow dynamic evaluation..You can then use variables such as q and x. However, these variables much be defined, e.g. in a separate .param q=1.602e-19 x=5 statement.

I've never used Ta caps so far. IMO, they are essentially Al polarized caps, but with higher density, higher price, higher ESR, potentially higher durability. If you need none of these, an Al electrol …

If you consider a standard two electrode capacitor, such as virtually all electrolytics and most ceramics, the ESL is given by the loop area that the current has to travel around when passing through the …

Your average Al electrolytic has a wonderful ESR-capacitance product in order to double as a snubber against nasty ringing at the MHz ballpark. This is cool because such ringing can easily appear due …

Here is an active circuit that eliminates several parasitic influences, like the scope probe and doesn't require another small and known capacitor (only a known resistor). …

How much effective charging current could I expect worst case (say the capacitor terminals just end in the air with no additional precautions)? …

There is no 1st order filter (I mean RC or LR) with a bandpass response. A single reactive element only makes half a bandpass. Therefore, for a 1st order bandpass you need already 2 reactive elements …
