Fixed Inductors are electrical devices used to introduce inductance to a circuit. A typical inductor is composed of a conducting wire wound into a coil which may have several sections. The inductance is determined by the core material, the number of turns, and the shape of the coil. Inductors are used in many electronic and electro-mechanical applications such as filters, power supplies, switching circuits, and antenna’s to name a few. A popular type of fixed inductor is the PL9219NLT.

Application Field:

The PL9219NLT is a fixed inductor specifically designed for use in switching power supplies and voltage-regulator circuits. It\'s low-profile feature allows it to be installed in very confined places, making it ideal for use in portable applications where space is in short supply. The PL9219NLT is made from high-efficiency ferrite to ensure maximum power density and minimize heat buildup. Its durable construction makes it ideal for industrial applications.

Working Principle:

The PL9219NLT is an inductor made from a coil of conducting wire, the number of turns, and its core material. Its induction is determined by the characteristics of the material, the number of turns and the shape of the coil. A DC current is passed through the coil causing a buildup of magnetic flux. When the DC current is turned off, the magnetic flux will collapse and a voltage spike will be induced across the coil. This induced voltage is used to control the circuit’s power supply or voltage regulator.

The PL9219NLT also features shielded construction to help retain its inductance under all loads. Its unique design allows it to operate without external components, while its EMI filter design ensures that the circuit will be shielded from interference from other electronics in the proximity.

The PL9219NLT is a highly efficient fixed inductor designed for use in switching power supplies and voltage-regulator circuits. Its low-profile feature, excellent power density, and durable construction make it ideal for use in portable applications where space is at a premium. Its shielded design ensures that it will retain its inductance under all loads, while its EMI shield will protect the circuit from interference from other electronics.
