Fixed Inductor

Fixed inductors are parts used to store energy in the form of a magnetic field. They are static components, meaning the values of their inductance do not change over time and are intended to remain constant. Fixed inductors are commonly used to facilitate current or voltage control, serving a variety of functions including signal filtering, energy storage, and signal coupling. They are widely used in television receivers, receivers, and modern automation systems. One example of a specific fixed inductor is the PL9227.

PL9227

The PL9227 is a fixed inductor that is copper-based, high-performance, and features a low profile of 6.2mmx7.2mm. The inductance range of the PL9227 is 0.51µH-100µH, with tolerance values of plus or minus 1%, plus or minus 2% or plus or minus 5%. It is capable of a Qmin up to 40. The parts feature a temperature instability of 100ppm/°C max. The PL9227 is RoHS compliant and halogen-free.

Application Field

In the field of consumer electronics, the PL9227 can be used as a filter coil in television receivers. Additionally, the PL9227 can be used in BGA packages to support products such as power amplifiers. The device also has a wide variety of industrial applications, such as in motor driver circuits that require a stable current, and any low-profile circuits that require a fixed inductor component.

Working Principle

The working principle of the PL9227 is based on the idea of inductance. Inductance is the ratio of the magnetic field that is generated when current is passed through a wire loop or coils. The PL9227 contains copper wires wound in a coil, which creates a fixed magnetic field when electrified. This magnetic field stores energy in the form of a magnetic field and induces a current when a different voltage is applied to the coil. This current flows through the winding and results in a voltage across the component.

Overall

The PL9227 from Pulse Electronics is a high-performance, copper-based, fixed inductor component. It has a wide-ranging application field including consumer electronics, BGA packages, motor driver circuits, and low-profile circuits. It operates based on the principle of inductance, with a magnetic field generated when current passes through its copper wire wound coils. The magnetic field stores energy, resulting in a current that flows through the winding.
