Fixed inductors that are specifically designed for high-frequency switching power supplies or telecom power supplies use PT750-1700HM as an example. Their main purpose is for filtering, frequency selection, oscillation, noise control, and impedance transformation in various applications. As a result, this type of inductor is widely used in the industry.

The PT750-1700HM fixed inductor is a type of self-shielding toroidal core inductor. It has a wide working temperature range from –60°C to +125°C and is designed for high-frequency and high-current applications as well as low-flow and high-capacity power supplies. It is also suitable for switch-mode power supplies and voltage-controlled oscillators.

The working principle of the PT750-1700HM is based on the induction law – when the current flowing through the inductor changes, a self-induced electromotive force is generated, and this electromotive force is opposite to the external current, thus making the inductor realize impedance conversion. It is a non-linear device whose properties change with the operating frequency. Due to its low resistance, the device allows for the transmission of high-frequency signals while ensuring minimal signal loss.

In terms of application, the PT750-1700HM fixed inductor can be used for filter and impedance transformation in switching power supplies, DC to DC converters, PFC circuit, AC to DC converters, LED lighting, and other electronic devices. Moreover, because of its low DC resistance, it is often used in voltage-controlled oscillator circuits to generate necessary voltages for certain procedures. They are especially applicable for high-temperature working conditions or noisy environments. The PT750-1700HM fixed inductor is also suitable for use in high-frequency circuits where spurious frequency components must be attenuated significantly, like storage devices, communications systems, and power phase control systems.

In conclusion, the PT750-1700HM is a type of fixed inductor that has an extended working temperature range and is designed for applications in high-frequency, high-current, low-flow, and high-capacity power supplies. It is mainly used for filtering, frequency selection, oscillation, noise control, and impedance transformation. Through its working principle and application range, the PT750-1700HM proves to be a reliable and robust device for the completion of various tasks and is an important component in the industry.
