Fixed inductors are electronic components that use inductance to store energy in a magnetic field. Inductors usually consist of a coil of insulated wire wrapped around a core of ferromagnet or around a ferrite core. This coil is usually wound in a helical shape and a magnet is driven through the winding layers of the coil, inducing a current that flows around the wire windings that generates a magnetic field. The magnetic field created by the coil stores energy, and this stored energy can be released from the magnetic field when it is disrupted by an outside force. Fixed inductors are used in a wide range of applications such as power supplies, communications, automobiles, audio and video applications, and in any electronic circuit that requires a stored or continuous current.

The PL9409T is a fixed inductor range from Pulse Electronics Power Pulse Division that offers high current capability in a low profile – height less than 2mm. It is designed for applications such as DC-DC converters, switching power supplies, output filter, coupling, and current limiting. The inductors are miniaturized, making them an ideal choice for compact electronic devices.

The core of the PL9409T is made from a ferromagnetic ferrite core that improves power handling and provides reliable operation over a wide temperature range. The ferrite core stores the majority of the magnetizing energy and optimizes the inductance performance of the component. The winding layers are composed of windings constructed of small gauge wire, providing a continuous inductance and current flow. The coil is additionally coated with tape to prevent any short circuits. Combined, the ferrite core and the windings provide optimal inductance performance of up to 2.7µH while handling high currents of up to 3.9A.

The PL9409T has applications across a variety of industries due to its low profile and current handling characteristics. It can be used in a variety of DC-DC converter designs due to its high current capability and saturation characteristics. The inductor also finds uses as an output filter component for power supplies, as well as in audio and video applications. Finally, the PL9409T is also useful for current and voltage limiting applications, due to its high-inductance characteristics.

In summary, the Pulse Electronics Power Pulse Division’s PL9409T is a fixed inductor range that provides high current capability in a compact, low profile package. The ferromagnetic ferrite core optimizes inductance performance and helps to improve power handling. The component also provides excellent saturation characteristics, making it suitable for use in DC-DC converters, power supplies, audio and video applications, and for limiting current and voltage. With its high current capability and low profile design, the PL9409T is an ideal choice for many electronic projects.
