Fixed inductors are parts of a variety of electrical and electronic circuits. They are particularly useful for providing inductance in circuits, as they are small, relatively inexpensive, and produce very consistent results in different types of circuits. This article will discuss the application field and working principle of the PM0603G-R39J, a fixed inductor manufactured by TDK.

Application Field

The PM0603G-R39J is designed for use in high-frequency choke circuits, and is ideal for use in automotive electronics, navigation systems, cellular phones, and other systems that utilize an RF choke. It is also suitable for use in EMC/EMI filters, general circuit decoupling, and low-frequency choke applications. All of these applications are dependent on the high quality of the inductor as well as its ability to block high-frequency signals.

Working Principle

The working principle of a fixed inductor is based on the fact that when electric current passes through a conductor, it creates a magnetic field, which then induces a voltage in the conductor. This is the basis for Faraday\'s law of induction. In the case of the PM0603G-R39J, this induced voltage is used for the purpose of providing choke and filtering circuits for the various applications mentioned earlier.

The PM0603G-R39J features a PCB-mountable design with a maximum current rating of 1.6A and a maximum DC resistance of 1.1 ohms. The inductance range of the inductor is .2mH–100mH, and it has a self-resonant frequency of 40MHz. The device is rated for an operating temperature range of -40°C to +105°C.

The PM0603G-R39J also features a circuit design that allows it to have very consistent performance across a wide range of frequencies. This means that when using the inductor in a circuit, the circuit will operate reliably regardless of the frequency it is subjected to.

Conclusion

The PM0603G-R39J is a fixed inductor designed for high-frequency choke circuits, EMC/EMI filters, general decoupling, and low-frequency choke applications. It features a maximum current rating of 1.6A and an operating temperature range of -40°C to +105°C. Additionally, it has a high self-resonant frequency of 40MHz, which allows for consistent performance across a wide range of frequencies. This makes the PM0603G-R39J an ideal choice for a variety of applications.
