Introduction
SRU3014-4R7Y is a type of fixed inductor produced by Ever River Electronics under its SRU3000 series. It is a square 5.8mm × 5.8mm board mountable type with a current rating of 2A and a 0.2Ω DCR. Its application field and working principle are discussed in the following sections.Application Field
SRU3014-4R7Y belongs to the family of fixed inductors under the SRU3000 series. The device is compliant with low voltage, low profile, and fine grain size requirements for the mobile board market. SRU3014-4R7Y is mainly suitable for providing parallel and series circuit with return flow for a variety of electronic circuits, such as audio, digital camera, and PC-based applications.Under the SRU3000 series, SRU3014-4R7Y is applicable for use in numerous power and switching converter circuits, low-frequency radio-frequency signal processing circuits, artificial wells, signal filtering circuits, and low-power DC-DC converters. Design application of SRU3014-4R7Y also includes providing low-cost choke coils and storage coil applications.Working Principle
When electric current passes through SRU3014-4R7Y, the device stores the energy in a magnetic field produced around it and generates counter emf that opposes the flow of current. The resistance against the current flow is called inductance, which is measured in units of henries (H).Originally, SRU3014-4R7Y acts as a short circuit when no current is flowing. As current starts to flow, the initial current is high as the magnetic field essentially provides resistance. As current passes, the magnetic field increases, thus reducing the current. The current eventually reduces to low levels as the saturation point is reached.SRU3014-4R7Y also works on this same principle when the current is interrupted. The residual magnetic field builds up a counter emf, which opposes the sudden change of voltage. This causes the current to continue flowing from the inductor and resist the voltage change.Conclusion
To summarise, SRU3014-4R7Y is a type of fixed inductor that is mainly used for providing parallel and series circuits with return flow for various electronic circuits. It operates using the principle of self-induction where a magnetic field is generated when a current passes through the device. This magnetic field provides resistance against the current flow as well as counter voltage when current is interrupted. SRU3014-4R7Y is mainly used for power and switching converter circuits, low-frequency radio-frequency signal processing circuits, artificial wells, signal filtering circuits, and low-power DC-DC converters.The specific data is subject to PDF, and the above content is for reference
