Introduction:

Fixed inductors, or sometimes referred to as ‘inductors’, are windings of insulated wire around a core, designed to provide a specific inductance in a circuit. This inductance is caused by the magnetic field generated by the current flow through the winding. Fixed inductors come in various shapes and sizes. The common type are axially leaded, wire-wound, and surface mount.

1226AS-H-2R7M=P2 Application Field

The 1226AS-H-2R7M=P2 fixed inductor is a surface-mount inductor specifically designed for high-frequency, high-temperature applications. It features low DC resistance, very low AC losses over a wide frequency range, and excellent high frequency characteristics. The 1226AS’s maximum operating temperature of 260°C is well above the maximum operating temperatures of other fixed inductors, which range from 120°C to 180°C. This makes the 1226A ideal for uses in high-temperature environments, such as automotive, aerospace, and industrial light fixtures.

Working Principle

The 1226AS-H-2R7M=P2 fixed inductor’s working principle involves the combination of magnetic induction and self-induction. Magnetic induction is what causes current to flow through the inductor when a voltage is applied. Self-induction is the reversible reaction of magnetic induction, whereby the inductor generates an opposing voltage that opposes the applied one. This combination of magnetic induction and self-induction is what creates the inductor\'s “fixed” inductance. The amount of inductance depends on the number of turns in the device, the diameter of the coil, and the permeability of the core materials.

Fixed inductors also feature two basic characteristics – impedance and inductance. Impedance is a measure of the opposition of an electrical current to flow through the inductor. The electromagnetic field generated by the inductor causes this impedance. Inductance, on the other hand, is the measure of the amount of magnetic coupling between the windings. This coupling determines how much of the current is stored in the inductor’s magnetic field.

When a fixed inductor is in operation, the self-inductive effect is induced, causing the inductor to store energy in its magnetic field. This energy is not used directly, but rather, the action of the magnetic field on the inductance induces an electrical current in the circuit, which can then be used to power other components. The size of the inductor and the amount of current it can store in its magnetic field depends on the number of turns in the windings.

Conclusion

In conclusion, the 1226AS-H-2R7M=P2 fixed inductor is designed for use in high-temperature and high-frequency applications. Its surface-mount design and high-temperature operating range make it suitable for use in a variety of automotive, aerospace, and industrial applications. It works through the combination of magnetic induction and self-induction, storing energy in its magnetic field. This energy is then released in the form of an electrical current to power other components.
