Fixed inductors are electronic components designed to generate a magnetic field at a specific frequency to provide inductance in a circuit. The SCH4312-390 inductor is a rigid inductor that is mainly used for bypassing the high-frequency path of decoupling capacitors in circuit designs. It is a high-performance inductor designed to meet the demands of high-frequency applications. It has an excellent heat resistance and is RoHS-compliant.

Appearance of SCH4312-390

The SCH4312-390 is available in a 1210-inch SMD package and designed for use in surface mount printed circuit boards. It has a greenish black organic surface and a white substrate. The top of the device is embossed with a "U" logo and a lot mark.

Technical parameter of SCH4312-390

The SCH4312-390 has the following technical parameters: rated current (Ir) - 1.0A, DC resistance (DCR) - 0.024 Ω, inductance (Idc) - 37.4 nH ± 20%, package - 1210 inch SMD.

Working Principle of SCH4312-390

The SCH4312-390 is an integral part of the high-frequency circuit, as it releases stored energy in a controlled manner through an electromagnetic field generated by the induced current. It works by creating a magnetic field that is maintained by the current flowing through it. When the current changes, the magnetic field also changes, thus creating an induced current in the circuit. This induced current has an opposite polarity to the original current, which creates resistance and helps to control the current.

Application Field of SCH4312-390

The SCH4312-390 inductor is a high-performance inductor designed to meet the demands of high-frequency applications. It is mainly used as a bypass capacitor to filter out high-frequency signals in high-frequency circuits, such as telecommunication circuits, dedicated signal path components on logic boards, and high-frequency power conversion recirculation circuits. It is also widely used in LED lighting, LCD panel displays, and automotive electronics applications.
