Thanks. As you may know, I am an "innocent" when it comes to this.
I cannot see needing more than 30/50 volts. I am thinking a range of 100pF to 1 uF should suffice. At this point in my studies, I am playing with bypass and coupling in transistor circuits, basic filters and ICs like the 385 and timers like the 555/556.
I am following Boylestad/Malvino/Real analog and so basically trying to replicate a college curriculum. If I outgrow the box, not a big loss; but that is unlikely.
Ease of use and a small footprint would be helpful. I have come to appreciate the importance of capacitance in just about any circuit.
For L, I do not have enough experience to know how to respond to your request. I am not doing much over a few 100 kHz and 30 VDC. Inductance is my next sequence.
I am jumping around a little with some active circuits, but nothing yet has had much to do with inductance other than transformers which I "understand" on a middle school level. And I do understand EMF and electromagnetism, rt hand rule, etc. But that is about it. Nothing with real analysis.
