Fixed inductors are important electrical components used in many applications. The SRU2013-470Y is a type of fixed inductor that is commonly used for circuit protection. This article will discuss the application field and working principle of the SRU2013-470Y.

The SRU2013-470Y is a radial-leaded, through-hole, fixed inductor that is used primarily in consumer electronics. It provides superior inductance performance with a low DC resistance and is ideal for use in power conditioning circuits, filter circuits, and line protection circuits. This inductor is rated for an operating temperature range of -40 °C to +85°C.

The SRU2013-470Y has a magnetically shielded construction which helps to reduce the effects of near-field interference caused by other components in the circuit. The coil structure is wound on an insulated core with a self-supporting magnetic structure that effectively reduces leakage fields. The SRU2013-470Y\'s self-supporting magnetic construction also reduces the need for additional shielding and helps to keep its size and weight to a minimum.

The SRU2013-470Y is composed of a sealed, cylindrical body that houses an internal wound coil. The coil is made of a high temperature-resistant enameled copper wire and is wound on an insulated ferrite core. This helps to ensure that the coil structure is stable and robust during usage.

The SRU2013-470Y has an inductance of 470～520mH when measured from 10kHZ to 500MHz. The inductance can be adjusted by changing the number of turns of the copper winding. The DC resistance of the inductor is typically 0.15 Ω. This low DC resistance allows the SRU2013-470Y to handle large current flows without generating too much heat.

The SRU2013-470Y\'s working principle is based on Faraday\'s law of induction. When current passes through the inductor, a magnetic field is created which induces an electromotive force (EMF). This EMF opposes the change in current, causing it to decrease and the current to eventually stabilize to a certain level even when the voltage stays the same. This allows the SRU2013-470Y to be used in circuits as a filtering and protection component.

In conclusion, the SRU2013-470Y is a radial-leaded, through-hole, fixed inductor that is primarily used in consumer electronics. It is rated for an operating temperature range of -40 °C to +85°C and offers superior inductance performance with its low DC resistance. Its magnetically shielded construction and self-supporting magnetic structure reduce the need for additional shielding. The SRU2013-470Y\'s working principle is based on Faraday\'s law of induction, which helps to protect circuits from voltage and current fluctuations.
