Fixed Inductors

ER1025-02KS Application Field and Working Principle

Fixed inductors (FIs) are a type of passive components used in electrical devices. They are commonly used for filtering and sooth as part of voltage regulator circuits. Fixed inductors are used on a wide range of electronic devices, including automotive, phone, and radio systems.

The ER1025-02KS fixed inductor is manufactured by EFJohnson Technica. It is a high-performance component that is designed for use in a variety of applications. The ER1025-02KS is especially popular in radio and phone systems, and it can be used in both AC and DC circuits. It is a small component, with a maximum diameter of 12mm and a maximum height of 8mm. The component has a low inductance and a low profile.

In terms of its electrical specifications, the ER1025-02KS has a rated DC current of 0.4A, a maximum DC resistance of 0.085ohm, a SRF of 11.5MHz, an inductance of 0.8-2.2uH, a DC resistance of 0.0011ohm, and a minimum Q factor of 65.

The ER1025-02KS is a classic example of a fixed inductor in terms of its operating principle. It works according to Faraday\'s law, which states that an electro-magnetic field is induced by the movement of a conductor under an externally impressed current. The impedance of the inductor will vary with frequency and current, and this in turn will affect the operation of the overall circuit.

The ER1025-02KS fixed inductor is a reliable component that is designed to withstand a wide range of temperatures and environmental conditions. It is easy to install and its low profile and dimensions create a great deal of flexibility in terms of application. It is suitable for use in a large range of devices, from radios to phones and is an ideal choice for those looking for a reliable radio component for their system.
