Fixed Inductors

An inductor, also known as a coil, chok or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. Inductors are used in a wide variety of applications and are particularly important in oscillators, filters, tuned circuits and inductive power supplies.

The ILSB0805ERR39K is a general purpose axial-leaded inductor from the ILSB series. It supports DC operate up to 1GHz and features 220 Ω / 100nH with SRF 18.9GHz and Q min of 63. The part has an inductance tolerance of ±10% and can handle up to a maximum operating temperature of +125°C. The ILSB0805ERR39K is designed to be used in cellular phones, GPS, Wi-Fi, Bluetooth, RFID, and other wireless and digital electronic systems.

ILSB0805ERR39K Working Principle

The ILSB0805ERR39K is a fixed –wire wound inductor. A wire is wound around an insulated core. With wire wound inductors, the higher the number of turns, the higher the inductance. This can be used to produce a specified inductance.The core is a non-magnetic material such as ferrite or air. This determines the maximum amount of inductance that can be achieved. The higher the permeability (magnetic properties) of the core material, the higher the maximum value of inductance.

When current flows through the wire wound coil, magnetic flux is generated that is proportions to the amount of current flowing through the coil. This flux produces an opposing voltage that tends to limit the current flowing through the coil. This is known as inductance.A certain amount of DC resistance is always present, which causes heating of the coil and power dissipation. The higher the number of turns, the higher the DC resistance and the resulting power dissipation.

Conclusion

The ILSB0805ERR39K is a general-purpose axial-leaded inductor from the ILSB series. It supports DC up to 1GHz, 220 Ω / 100nH with SRF 18.9GHz, and Q min of 63. The inductor is designed for use in cellular phones, GPS, Wi-Fi, Bluetooth, RFID, and other wireless and digital electronic systems. It is a fixed-wire wound inductor, and works by generating an opposing voltage that tends to limit the current flowing through the coil. With wire wound inductors, the higher the number of turns, the higher the inductance and DC resistance and, hence, the power dissipation of the coil.
