WHAT TYPE OF INDUCTOR?
Suppose you have been shown a circuit requiring a 10nH choke. Can any type of 10nH choke (inductor) be used? How many different types of 10nH inductors are there? How do you know which type to use? The answer to this very complex. There are many different 10nH inductors and most circuit diagrams do not provide sufficient information for you to get (or make) the correct type. The value “10nH” is like saying a resistor is “1k.” It does not tell you all the features you need to know such as wattage or tolerance. The same with a 10nH inductor. The value tells you nothing about its physical size, the size of the winding etc. A 10nH inductor can be created by winding thick wire or thin wire onto a core of magnetic material. The inductor using thick wire will be larger and the resistance of the coil will be less. The two 10nH inductors will perform completely differently when connected to some circuits. The following circuit shows a typical use for an inductor. It is connected across a piezo
