Fixed inductors are inductors with a fixed inductance value and are one of most commonly used components in electric circuits. The 103-153G series are a type of fixed inductor, generally designed for surface mount applications and are available in a standard, small, low profile package and an option with radial termination with a patented design for enhanced performance. The 103-153G series is an excellent choice for high-current, low-profile applications.

This 103-153G series of fixed inductors has a wide range of applications. In power supply systems, they are used as a filter of AC noise, as transformers for higher voltage due to their large inductance and to protect circuits from voltage surges. In automotive applications, they are used to suppress EMI and as buffering coils for DC/DC converters. They are also used in industrial motor controls, robotics, PC board and LED lighting applications.

The 103-153G series of fixed inductors can be categorized into high temp insulation, high current density, low profile, low noise level, low cost and wide frequency band. High temperature insulation ensures the power device can operate in extreme temperature environment and can bear high insulation voltage. High current density feature of this series can reduce the chip size while maintaining the power output. The low profile feature can help reduce the installation space requirement for the application. Low noise level performance of this series ensures the circuit can work stably under extreme environment and wide frequency band feature makes this series suitable for a range of applications.

The working principle of these fixed inductors is based on the Faraday’s law of induction, in which a changing current in a conductor will generate a changing magnetic field in its surrounding space. When the current in the conductor increases, the flux density increases and thus creating a magnetic field in its surrounding space. This changing magnetic field will induce current, generating back electromotive forces in the circuit. The magnitude of induced current in the circuit is determined by the inductance of this particular inductor and this establish the working principle of fixed inductors.

In conclusion, the 103-153G series of fixed inductors are designed for surface-mounted applications. It has a wide range of applications, such as in power supply systems, automotive applications, industrial motor controls, robotics, LED lighting, etc. It can be categorized into high temperature insulation, high current density, low profile, low noise level, low cost and wide frequency band. Furthermore, the working principle of this series is based on the Faraday’s law of induction.
