Fixed Inductors, including the PT500R-1750HM, are passive components that store and release electrical energy in the form of electromagnetic fields. They are essential parts of many electrical and electronic circuits.The PT500R-1750HM is a particular type of fixed inductor developed by Panasonic. It is an ink-filled core with up to 5000uH induction at 100kHz and 1V. It has low power loss, high temperature stability, and good ripple noise suppression.The most common application for the PT500R-1750HM is in power supplies and power factor correction (PFC) circuits. It can be used in both AC and DC circuits, making it a highly versatile and cost-effective part. In addition, it is suitable for use in compact devices, where its small size and high inductance make it suitable for applications that require a small, high-performance inductor.The key principle of operation for the PT500R-1750HM is Faraday’s Law of Induction. This states that when a conductor is moved in a magnetic field, or when a magnetic field is changed, it induces a voltage in the conductor.In the case of the PT500R-1750HM, an alternating current (AC) is applied to the inductor. This generates a magnetic field which then induces a voltage in the inductor. This voltage is then fed back to the input of the inductor, creating a closed circuit. The voltage induced in the closed circuit is proportional to the rate of change of the magnetic field.The voltage induced in the PT500R-1750HM is then used to control the power supply or PFC circuit. It can be used to regulate the voltage, current, and ripple in the circuit, ensuring proper operation of the device or system.The PT500R-1750HM is also often used in rectifier circuits. A rectifier circuit is used to convert AC input power to regulated DC output power. The inductor is used in conjunction with a diode, capacitor, and resistor to control current flow and create a steady output. The inductor is used to limit inrush current when the power supply is first turned on. It also helps to regulate the ripple voltage produced by the rectifier circuit.In addition to these applications, the PT500R-1750HM is also suitable for use in signal processing, radio receivers, filter circuits, and other applications. Its small size and high inductance make it suitable for high frequency and low voltage circuits.Overall, the PT500R-1750HM is a versatile and reliable fixed inductor, suitable for a wide range of applications. Its high inductance and low power losses make it suitable for use in power supply and PFC circuits, rectifier circuits, and other low-voltage applications that require a compact, high-performance inductor. It is a popular choice for many electrical and electronic circuits.
