Fixed inductors are passive two-terminal electrical components that store energy in the form of magnetic flux. A variable resistor or variable inductor is used to adjust the current. The fixed inductor is used to maintain the current.

The IR02EBR39K is a fixed inductor from the IR02E Series manufactured by TDK. It is a compact radial-leaded inductor that has been developed for use in impedance matching circuits, filters, and noise suppression circuits. The IR02EBR39K has a high inductance of 39µH in a small surface-mount package. It is also rated for a high current rating of 1.2 Amps.

The IR02EBR39K is characterized by its low DC resistance, high self-resonance frequency, and high Q factor. Its operating temperature ranges from -40°C to +125°C and it has a rated temperature rise of 40°C. It also features a core material of ferrite, which makes it suitable for use in power circuits.

The IR02EBR39K can be used in a variety of applications, including power supplies, communications systems, automotive systems, and computing systems. It can also be used in audio systems, TVs, and portable appliances. Its high current rating and low DC resistance make it ideal for use in power circuits. The inductor can also be used as a filter or as a low-pass filter.

The working principle of a fixed inductor is based on Faraday’s law of electromagnetic induction. This law states that changing magnetic fields on a conductor produces an electric field around it. This electric field, in turn, produces an EMF (electromotive force) that produces a current in the circuit. The current flowing through the inductor creates a magnetic field, which stores energy in the form of magnetic flux.

When a current is applied to the inductor, the magnetic field created induces a EMF which opposes the original current. This is known as inductance. The inductance of an inductor is the ratio of the EMF produced to the rate of change of the current flow. As the current flow increases, the magnetic field increases, and thus the inductance increases.

The IR02EBR39K is an ideal component for applications where inductors are required to store energy in the form of magnetic flux. Its low DC resistance, high self-resonance frequency, and high Q factor make it well suited for use in a variety of circuits. Its compact size and high current rating also make it a good choice for power circuits. With its range of applications, the IR02EBR39K is a versatile fixed inductor that can be used in many applications.
