I have been looking for a very basic book on electronics, but many of them explain what the components do (and how they are made) and then go into designing circuits that do stuff. They tell you to ...
I'm trying to understand a schematic of an RFID reader. Circuit: What capacitors are used - electrolytic or ceramic capacitors? I've seen schemes of RFID readers that use electrolytic capacitors, ...
I have designed a simple LC band stop filter with a center frequency of 433MHz. The schematic looks like: The caps are NP0 0603 and the inductors are from the Coilcraft 0603HP series. The values ...
When thinking about substituting components, I know that resistors are easily substituted within their 10%/5%/1% tolerances. But what about wattage on a resistor? Is it safe to do substitutions, say ...
I have a ceramic disc capacitor that got cooked in a power surge due to a faulty generator. The capacitor was between the fuse and transformer of a circuit board for a pellet stove. It is RED ...
In the answer to another question, I read that it's bad to short-circuit electrolytic capacitors. Why is that? What happens if I do?
I've got one of these cabinets, which I intend to use for storing electronic components: It has 24 drawers (each 175 x 69 x 37mm). Every drawer can be subdivided into up to six compartments by ...
