Types of Inductance
Air Core Inductor Inductance Calculator. See our other Electronics Calculators.. The following is a design tool which calculates the inductance of an air core inductor.
The carbon composition resistor exists over hundred years. In the beginning of the twentieth century, the resistors were produced without coating. The lead wires were directly soldered onto the resistor body. The only available resistor types until the 1960s, were wirewound and carbon composition. In the 1960s and 70s there was a shift in use of carbon composition resistors to other types like the carbon or metal film resistor.
Resistors designed specifically for use at high frequencies are made of metal film, to avoid creating the coil shape and reduce the parasitic inductance. Reactance and inductance calculations In AC circuits, Electrical impedance is the measure of the opposition that a circuit presents to the passage of a current when a voltage is applied.
Any core size line that intersects the LI² coordinate represents a workable core for the inductor if the core’s A L value is less than the maximum value obtained on the chart. 4. Required inductance L, core size, and core nominal inductance (A L) are known.
• Saturation of the core material means that the inductor will “lose” its inductance value for power signals higher than the saturation value. If I played 300W of music through the iron cored inductor above, it would behave more like the air cored inductor for signals larger than say, 200W.
What is a powder core? Powder cores are distributed air gap cores that possess many outstanding characteristics--high resistivity, low hysteresis and eddy current losses, and excellent inductance stability under both DC and AC conditions. Magnetics’ powder cores are not pressed with an organic binder, and therefore do not exhibit any thermal aging effects, as observed with powdered iron cores.
Before knowing what is inductor we should first know the definition of inductance. Definition of Inductance If a changing flux is linked with a coil of a conductor there would be an emf induced in it. The property of the coil of inducing emf due to the changing flux linked with it is known as inductance of the coil.

What is a Multilayer Inductor? A multilayer inductor contains a first conductive coil pattern and a second conductive coil pattern which are arranged in two layers in the upper part of a multi-layered body and are connected electrically in a consecutive manner in series to 2 more conductive coil patterns disposed in the lower part of the multi-layered body and therefore forming a spiral coil.
The parasitic inductance of thin film can be higher if it is executed as a cylindrical helix (metal film resistor). This higher performance comes with a cost, which can be factors higher than the price of thick film resistors.

Wire wound resistors naturally have some capacitance and inductance. Because of this, they influence the current flow in an alternating current circuit. This effect is usually not wanted.
