Fixed inductors are passive electrical components that store energy in the form of magnetic fields.

The fixed inductor ER1537-70JR is a general-purpose, high-frequency, shielded ceramic-core inductor that provides efficient energy storage for DC and AC electrical applications. It can be used for signal C filtering, output filters, power supply EMI suppression, and other applications.

The inductor ER1537-70JR features a molded shield, high inductance, and a robust construction. It is designed to provide excellent shielding characteristics and low DC resistance. This fixed inductor has a low ESR and high power levels for efficient signal filtering in low-frequency applications.

The ER1537-70JR consists of a metalized polyester film which is wound on a high-performance ceramic core. This core material offers low magnetic loss and high insulation resistance. The combination of these two materials makes the inductor resistant to temperature changes without sacrificing performance.

ER1537-70JR fixed inductors provide effective energy storage in a compact, low-profile package. They offer excellent frequency response across a wide range of frequencies and are designed for easy mounting on printed circuit boards. They are suitable for use in switching power supply circuits, and other high-frequency applications.

To understand the working principle of the ER1537-70JR, it is necessary to understand the basic principle of all inductors. An inductor is a device that stores energy in purely magnetic form. It consists of a coil of wires, usually around a core material, such as ferrite or iron powder. When an electric current passes through the coil, a magnetic field is created, which stores energy that can be retrieved later.

When an AC signal passes through the coil, the magnetic fields form and collapse at the rate of the AC signal. This energy is stored in the form of magnetic fields. As the current reverses direction, the energy is released again to the circuit, producing a voltage equal to the rate of change of the current. This process, known as Faraday\'s law of induction, is what makes inductors useful for filtering signals, suppressing noise, and other applications.

In the case of the ER1537-70JR, the combination of a high-performance ceramic core and metalized polyester film provides the necessary energy storage for DC and AC applications. The combination of materials also reduces noise and improves frequency response. As the inductor is shielded, it is particularly suitable for use in noisy or high-frequency applications.

The ER1537-70JR fixed inductor is suitable for use in many different applications, from signal filtering to power supplies and EMI suppression. It is a versatile and reliable device that can handle a wide range of frequencies and provides effective energy storage for efficient signal filtering.
