Fixed Inductors

Fixed inductors, also called choke coils, are commonly used in radio-frequency (RF) applications. They are designed to provide shielding from interference and passivity in circuits and reduce the negative effects of RF signals. In general, inductors are comprised of a coil of wire wound in a specific pattern, which helps to store and release energy over a certain period of time.

LQH32MN121J23L application field and working principle

The LQH32MN121J23L inductor is a type of fixed inductor designed specifically for RF applications. It is a shielded power inductor that can handle 1.4A current and has a rated inductance of 12uH with saturation current of 3.8A. Its ferrite core material is an important component of its construction, as it allows the inductor to have low DCR and high efficiency in its operation. Additionally, the LQH32MN121J23L inductor is RoHS compliant and has a maximum operating temperature of 150°C.

When used in RF applications, the LQH32MN121J23L inductor helps to suppress electrical noise from harmonic frequencies. This helps to ensure that any RF signals sent through the circuit will not be affected by the noise, allowing a consistent signal quality and making it possible to pick up even faint signals. The LQH32MN121J23L also serves to filter out unwanted noise from the signal, helping to improve signal-to-noise ratios.

The LQH32MN121J23L fixed inductor also helps to provide increased stability for DC-input signals. This is achieved by its inductance, which prevents the current flow from changing too quickly, allowing the signal to remain consistent. As such, it is commonly used in products that handle large currents, such as power amplifiers and switching power supplies.

Overall, the LQH32MN121J23L is an ideal choice for RF applications, as it is a highly efficient, shielded power inductor that can isolate weak signals and help to reduce the negative effects of harmonic frequencies. Additionally, its low DCR and RoHS compliant construction make it a reliable component that can be used in a variety of different circuits.
