Fixed inductors are electronic components that are designed to store electrical energy in a magnetic field when subjected to an electrical current. The amount of stored energy is dependent on the inductance of the component. Common fixed inductors include molded, axially wound and multi-layer wound. The LMXS121JM470HTAS is an example of a fixed inductor and is one of the most widely used in the industry.

Application Field

The LMXS121JM470HTAS is designed primarily for use in DC/DC converters, SCR and TRIAC circuits, EMI/RFI suppression, power supply, signal filtering, and other similar applications. It is also suitable for use in AC motor control, motor drive and changing AC line voltage or current. In addition, the LMXS121JM470HTAS can also be used in automotive and industrial equipment, telecommunications systems, medical devices, LED lighting, and other high-frequency applications.

Working Principle

The LMXS121JM470HTAS fixed inductor works on the principle of electromagnetic induction. When electrical current passes through a conductor, it produces a magnetic field, which in turn induces a secondary current in the conductor. This induced current is proportional to the amount of current passing through the inductor, and the strength of the magnetic field. The LMXS121JM470HTAS is designed to maximize the magnetic field generated when subjected to electrical current, thereby maximizing the induced current. This allows the LMXS121JM470HTAS to effectively store and release electrical energy.

The LMXS121JM470HTAS is a self-shielded, low-profile, surface-mounted device. It is constructed from a high-temperature thermoplastic overmold that provides insulation and protection from environmental conditions. The inductor also features an internal plastic bobbin, which keeps the windings securely in place and resists moisture. Additionally, the inductor has excellent EMI/RFI noise filtering characteristics, making it ideal for use in applications that require high levels of noise reduction.

The LMXS121JM470HTAS is designed for use in both DC and AC circuits, and is rated for operation up to 1.25A at temperatures between -40°C and +125°C. Its high inductance makes it suitable for use in both voltage and current regulation, and it is also available with a wide range of packaging options, including surface mount, through-hole, and vertical mount.

In conclusion, the LMXS121JM470HTAS is an efficient and reliable fixed inductor that is widely used in DC/DC converters, EMI/RFI suppression, motor control and other applications. It is designed to maximize the amount of stored energy in the magnetic field when subjected to an electrical current and features excellent EMI/RFI noise filtering. With its wide range of packaging options, the LMXS121JM470HTAS is a versatile and robust fixed inductor that can be used in a wide variety of applications.
