Fixed Inductors

Inductors are electronic components used in electrical circuits to store energy in the form of a magnetic field. Fixed inductors, sometimes called chokes, are used to selectively remove high-frequency signals or to reduce the current passing through a circuit. The SPM4030T-R60M is an 11mm x 11mm x 6.2mm surface mount inductor suitable for high-frequency applications, such as power supplies and DC-DC converters.

SPM4030T-R60M Application Field and Working Principle

The SPM4030T-R60M is a typical fixed inductor and is suitable for high-frequency applications such as DC-DC converters, DC-AC inverters, and power supplies. It provides a stable inductance in a wide frequency range, from 20 kHz to 30 MHz, by maintaining a current flow in the windings of the inductor. As the current is flowing through the windings, a magnetic field is created, storing energy which is then released back to the circuit.

When the current through the inductor is increasing, the magnetic field around the windings also increases, storing more energy. When the current is reduced, the magnetic field collapses, releasing the stored energy back to the circuit. This is how the inductor works, allowing it to maintain a stable inductance while filtering out high-frequency signals.

In addition to providing stable inductance, the SPM4030T-R60M also features a low DC resistance which helps to reduce the power losses associated with inductors. It is also capable of operating at temperatures from -40°C to +85°C, making it suitable for a wide range of applications. The inductor is rated at 6A and is suitable for use in enviroments where high moisture levels, high temperature extremes and variable heat sources are common.

The SPM4030T-R60M is a low-profile, surface-mount inductor which is designed for use in high-frequency applications. It is rated for 6A and provides a stable inductance in a wide frequency range, from 20 kHz to 30 MHz. The low DC resistance helps to reduce power losses and the inductor is capable of operating in temperatures from -40°C to +85°C, making it suitable for use in many different situations.
