Fixed Inductors

Inductors, or coils, are components used in electronics that store energy in the form of a magnetic field. Fixed inductors are inductors with a predetermined inductance value. They are used in many applications such as filters, oscillators, transmitters, and receivers. One particular type of fixed inductor is the SRR1260-390M.

SRR1260-390M Application Field

The SRR1260-390M is a surface-mountable wire-wound inductor with a higher self-resonant frequency, low DC resistance, and high current capacity. It operates at frequencies as high as 400MHz. The inductor is designed to filter out noise in radio-frequency applications, making it ideal for RF systems, VCOs, and wireless communication systems.

SRR1260-390M Working Principle

The SRR1260-390M works on the principle of induction. As an alternating current passes through the inductor, it creates a magnetic field which induces an EMF, or induced EMF, in the coil. The EMF produces a force which opposes the current, creating a voltage drop across the inductor. This voltage drop is dependant on the current and the inductance value of the inductor. This voltage drop causes the inductor to absorb energy, which is then stored as a magnetic field. When the electric current is removed, the magnetic field collapses, releasing the stored energy into the circuit.

Conclusion

The SRR1260-390M fixed inductor is a surface-mountable wire-wound inductor designed to filter out noise in radio-frequency applications. It operates using the principle of induction, where an alternating current passing through the inductor creates a magnetic field which induces a voltage drop across the inductor. This voltage drop causes the inductor to absorb energy, which is stored as a magnetic field. It is an ideal choice for implementing filtering, tuning, and feedback in RF systems.
