Fixed Inductors

Fixed inductors are electrical components specifically designed to constrain the flow of electric current to a certain level. The magnetic field generated by the coil of the inductor adds a reaction force to the flow of electrons. The PT250R-1500 is a fixed inductor that offers excellent ripple current and noise suppression for a voltage of 150V.

Application Field

The PT250R-1500 is primarily used in applications that require a large electric current carrying capacity and the suppression of undesired noise within the circuit. It can be found in a wide range of applications that include high-frequency switching power supplies, low-frequency power supplies, motor drives, electronic ballasts, and LED lighting.

Working Principle

The PT250R-1500 inductor works on the principle of electromagnetic induction in which electrical energy is transformed into a magnetic field. When a conductor is introduced to a magnetic field, it induces an electron flow and thus creates a current flow. The magnitude of the current induced depends on the magnitude of the inductor’s magnetic field.In the PT250R-1500, the current is induced by a mass of very thin wires wound tightly together to form a coil. The coil is generated using a special technique called “wind-winding”, which means that every single turn of the coil is wound to a specific tightness. Together, these turns form a closed loop that confine the electric field and enable it to amplify the magnetic field.This amplified magnetic field is what constrains the current flow to the desired level. As the current passes through the inductor, the windings cause a reaction force that opposes the electrons’ flow. This reaction force is what causes the current to remain at a consistent level, allowing the desired, regulated current to flow through the circuit.

Conclusion

The PT250R-1500 is an ideal device for power supplies, motor drives, and LED lighting applications. It has a large electric current carrying capacity and provides excellent ripple current and noise suppression, making it an invaluable component for these applications. The PT250R-1500 works on the principle of electromagnetic induction, using a coil of tightly wound wires to constrain the current flow to the desired level. With its superior features and great performance, the PT250R-1500 is a great choice for those looking for a reliable and efficient fixed inductor.
