PL9420T

Fixed inductors are passive components that store a certain amount of energy in the form of a magnetic field when current passes through them. The PL9420T is a high quality, surface mount 200mA three-phase, shielded power inductor designed and developed for use in wide range of applications where a reliable inductor is required. Its many features make it an ideal choice for consumer, industrial and automotive applications.

The PL9420T is a shielded power inductor with an integrated metal shield housing with a three phase structure. It has an excellent inductance tolerance, high current handling capability, high Rdc, low noise characteristics and provides superior EMI/RFI shielding. This combination of features makes it ideal for use in a wide range a range of applications, including consumer electronics, power supplies, automotive applications and industrial automation.

The main advantage of the PL9420T is its multi-phase inductor design. This design helps to reduce losses and improve efficiency by combining three inductors into a single package. It also helps to reduce the interaction of the magnetic fields generated by the inductors, which can lead to changes in the inductance value and other undesired effects. It also helps to reduce electromagnetic interference (EMI) and provides superior performance in EMI/RFI sensitive applications.

The working principle of the PL9420T is relatively simple. When the unit is energized, current flows through the inductor. The current causes a magnetic field to be generated around the inductor. This magnetic field then interacts with an oppositely wound coil that is placed around the inductor. This process is known as inductive coupling, and it generates a back-EMF voltage that opposes the current. This back EMF voltage, combined with the internal resistance of the inductor, causes an impedance that results in a reduction in current flow through the inductor.

The PL9420T is an ideal choice for a wide range of applications where a reliable, high quality inductor with superior performance and EMI/RFI shielding is required. It is particularly suitable for high current, high frequency applications such as power supplies, switched mode power supplies and consumer electronics. It is also suitable for use in automotive applications such as charging circuits, ignition coils and starter motors.

In summary, the PL9420T is a high quality shielded power inductor with a unique three-phase structure. It has excellent inductance tolerance, high current handling capability, low noise characteristics and provides superior EMI/RFI shielding. This combination of features makes it ideal for use in a wide range of applications, including consumer electronics, power supplies, automotive applications and industrial automation.
