PD75R-273K

Fixed Inductors

Fixed inductors, often referred to as chokes, can be found in nearly every electronic device from computers and cellphones to stereos and home appliances. The PD75R-273K is one such fixed inductor component that is widely used in power supplies to filter out any undesired high frequencies or help maintain power levels during a change in load. With so many applications in modern electronics, understanding how a fixed inductor like the PD75R-273K works and how to use it is essential for anyone working with electronics.

PD75R-273K Specifications

The PD75R-273K is a high-quality, lead-free fixed inductors designed for use in a wide variety of power supply applications. It consists of a 2.7 UD7 axial metal core, 500 mH inductance, and a 2.4 A current rating. It also features a ± 5 percent tolerance, a 0.02 Ω DC resistance, and a maximum operating temperature of 125 °C. The PD75R-273K is designed to operate at frequencies up to 100 kHz.

Application Field

The PD75R-273K is a versatile component with numerous applications in the world of electronics. It is primarily used in power supplies due to its high inductance and ability to filter out high frequency components. Additionally, it can be used to keep power levels steady during a sudden load change or to maintain a high level of precision in switching power supplies. It is also commonly used in amplifiers, antennas, clocks, sensors, medical equipment, and many other electronic devices.

Working Principle

The working principle of a fixed inductor like the PD75R-273K is fairly simple. It uses a single core of metal which is wound tightly with insulated wire to create a magnetic circuit. When an electric current is passed through the wire, it induces a magnetic field within the core which resists the flow of the current. As the current passes through the wire, it is "slowed down" and converted into a magnetic field which can be used for a variety of applications.

In a power supply, the PD75R-273K acts to filter out any undesirable high-frequency components that could cause interference or damage other components. It is also used to keep power levels stable during sudden changes in load. In amplifiers, it can help reduce distortion by controlling the input and output voltages. In antennas, it can act as an impedance matching component and help increase the efficiency of the system. And in medical equipment, it is often used to maintain precision in electrical signals.

Conclusion

The PD75R-273K is a versatile fixed inductor component with many applications in the world of electronics. It consists of a 2.7 UD7 axial metal core, 500 mH inductance, and a 2.4 A current rating with a ± 5 percent tolerance and a 0.02 Ω DC resistance. It uses a single core of metal which is wound tightly with insulated wire to create a magnetic circuit which resists the flow of current and can be used to filter out undesired high frequency components, keep power levels steady, and reduce distortion in amplifiers. This makes it an indispensable component for anyone working with power supplies, antennas, medical equipment, and many other types of electronics.
