Fixed Inductors: MS1813-8SH application field and working principle

Fixed inductors are an essential component in modern electronic circuits, and the MS1813-8SH is a common example of this component type. Understanding its application field and working principle is vital in properly selecting it for an electronic circuit.

Application field

The MS1813-8SH is a four-terminal surface-mounted inductor specifically designed for use in common-mode noise suppression filters, RF (radio frequency) circuits and, in some cases, power supplies. It is a high-inductance type, with inductance value ranging from 0.1 to 33mH. This means this component can withstand large current flows, making it suitable for larger circuit applications.

Typical circuit applications include use with low- and high-frequency filters, and power supplies. Common-mode noise suppression filters, for example, are used in a wide range of electronic devices, such as Power Amplifier circuits, as well as numerous industrial components. The MS1813-8SH inductor has been designed for maximum efficiency when used in this context.

Working principle

In the most basic sense, an inductor is a passive electrical component consisting of a coil of wire. This wire carries a current, the flow of which induces a magnetic field. This magnetic field stores energy in the form of a magnetic field, set up by the flow of current.

The working principle of the MS1813-8SH is very similar. It consists of two coils of wire, connected at either end. Inside the device, there is a core, usually made of ferrite, which is surrounded by the wire. Inside the core, there is an inductor which is used to slow down the current, and to store energy, while the core material helps to reduce the effects of interference.

When a current is sent into the device, the current flows through the coils, and this induces a magnetic field. This magnetic field is then used to store energy, and when the current stops flowing, the magnetic field slowly collapses, releasing the stored energy. This energy is then used to send current back into the circuit, known as inductive reactance.

Conclusion

In summary, the MS1813-8SH is a four-terminal surface-mount inductor specifically designed for use in applications such as common-mode noise suppression filters, RF circuits and power supplies. Its working principle is based on the conductive flow of current through the coils, which induces a magnetic field that is used to store energy. This stored energy is then used to send current back into the circuit, often referred to as inductive reactance.
