PTKM100R-50H

Fixed inductors are electrical components that store energy in the form of a magnetic field when a current passes through them. The PTKM100R-50H is a fixed inductor that is specifically designed for high-frequency, high-current applications. It is an ideal choice for high-frequency inverters, switched-mode power supplies, and RF (radio frequency) circuits. This article will discuss the application field and working principle of the PTKM100R-50H.

Application Field

The PTKM100R-50H is designed primarily for high-frequency, high-current applications. It is used in inverters, switched-mode power supplies, and RF circuits. It is ideal for applications where the frequency is greater than 500kHz and the current is greater than 2A. It is also suitable for use in automotive applications, including DC-DC converters and power supplies for electric vehicles.

The PTKM100R-50H’s main advantage is its excellent high-frequency performance. It has a wide operating frequency range from 0.5MHz to 10MHz and can handle up to 10 A of peak current. This makes it suitable for high-frequency applications such as RF circuits and high-density power converters. It also has a high frequency stability, making it ideal for use in applications where frequency stability is important.

The PTKM100R-50H also offers excellent temperature performance, with a temperature coefficient of 0.1%/°C. This ensures that the inductance remains constant over a wide temperature range, making it suitable for use in temperature-critical applications.

Working Principle

The working principle of a fixed inductor is based on Faraday’s Law of induction. When a current passes through the inductor, a magnetic field is formed, which stores energy in the form of a magnetic field. In the case of the PTKM100R-50H, this magnetic field is used to induce a voltage in an adjacent circuit. The magnitude of the induced voltage is proportional to the rate of change of the magnetic field. As the frequency of the current increases, the magnetic field changes more rapidly, and the voltage induced in the adjacent circuit increases.

The PTKM100R-50H inductor is wound with a special type of wire that has a high resistance. This helps to limit the current and reduce losses in the inductor. It also helps to reduce stray magnetic fields that can interfere with other nearby electronic components.

Conclusion

The PTKM100R-50H is a fixed inductor designed for high-frequency, high-current applications. It has a wide operating frequency range and can handle high currents without losing its performance. It also has excellent temperature performance, making it suitable for temperature-critical applications. The working principle of a fixed inductor is based on Faraday’s Law of induction, and the PTKM100R-50H is designed to maximize performance.
