Fixed Inductors

Fixed inductors are components that store energy in a magnetic field when current is flowing through them. They are used in electrical circuits to control current flow and voltage changes as well as to provide signal filtering and RF protection. A fixed inductor is composed of wire loops wound around a coil form and encased in a housing that is usually made of ceramic or plastic. The SCEP105L-7R2 is an Chip Inductor that is part of the Fixed Inductors family.

SCEP105L-7R2 Application Field

The SCEP105L-7R2 chip inductor is a small size, low profile, surface mount inductor. It is designed for general purpose RF, IF, and impedance matching applications in the frequency range of DC to 1GHz. It has high current handling capability and low temperature coefficient. It is suitable for portable electronic units such as cellular phones, portable audio equipment, and satellite radios.

SCEP105L-7R2 Working Principle

The SCEP105L-7R2 is constructed with a self-supporting ferrite core and solderable tinned leads. The core is made of ferrite which allows the current to flow through the core with minimum loss, making it suitable for high frequency applications. When current flows through the windings of the inductor, the core stores the energy in the form of a magnetic field. This energy is later released, through the inductor, producing a voltage that is proportional to the amount of current flowing through it.The SCEP105L-7R2 has a low DC resistance and excellent Q-factor, making it suitable for high-Q, impedance matching applications. Its high self-resonant frequency reduces core losses at high frequency, making it suitable for high-frequency applications. The inductor has a wide operating temperature range from -55°C to 125°C and excellent high temperature stability which makes it suitable even for high temperature applications.The inductor also has a high current saturation capability, making it very efficient even at high frequencies. It also has low electromagnetic interference which reduces unwanted noise in the circuit.

Conclusion

The SCEP105L-7R2 is a small size, low profile, surface mount inductor that offers excellent signal fidelity and stability for a variety of applications. Its wide operational temperature range and low DC resistance makes it suitable for high-frequency applications, impedance matching, and high Q-factor applications. Its high temperature stability and low electromagnetic interference make it suitable for applications such as cellular phones, portable audio equipment, and satellite radios.
