What are ideal inductors?
An ideal inductor is an electrical component that has no resistance and no capacitance and has only inductance. Since an ideal inductor has no resistance it will not radiate or dissipate any energy. Inductance depends on the shape of the coil, the number of turns, and the permeability of the core.
How do I choose a coil?
As a rule of thumb, the higher the wattage level of your device or the lower the resistance level of your coil, the smaller your coil may be. Small coils will give you stronger, richer flavor, while large coils will give you bigger clouds.
What should be considered when choosing an inductor?
What type of inductor, leaded, SMD inductor, value, resistance and many other aspects of the performance need to be considered before the final choice is made. The first and most important stage in the inductor selection process is to know the application for the inductor.
What kind of inductors are used in surface mount?
Component format: For large scale production, virtually all the components used are surface mount. Although many leaded inductors are available, there is also a very good selection of SMD inductors. In fact SMD inductors are available for most applications.
What do you need to know about RF inductors?
Apart froth inductance of the inductor, there are some other key parameters that need to be considered when selecting and buying an inductor for RF applications. One of these is the Q of the inductor. The Q factor essential describes the ratio of the reactance of the inductor to its resistance.
Which is larger a power supply or an inductor?
Those for power supplies will tend to have larger inductance levels, they will have a larger current capability, and will often be physically larger than those that might be used in, for example, RF applications, where much smaller current levels, higher frequencies and smaller sizes are the order of the day.
