Fixed inductors, also known as fixed chokes, are passive components used to introduce inductance into a circuit. The SRU2016-470Y inductor is a high-energy, high-frequency, low-loss inductor designed for use in power supplies, RF, and microwave applications. This component provides stable impedance across a wide range of frequencies and temperatures.

The SRU2016-470Y is a fixed inductor, meaning that it has a fixed inductance and size; no additional components or tuning is necessary. It is constructed with a large ceramic core, which provides a low DC resistance. This is then wrapped with a shielding copper sleeve and air, which helps limit flux leakage and reduce inductance. The inductor is then encapsulated, which ensures high EMI/RFI immunity and low thermal resistance.

The SRU2016-470Y provides high energy density, high current capacity, and a high electrical performance at high frequencies. The high current capacity is due to its high DC resistance and the ability to withstand up to 25A peak current without saturating. This allows the inductor to be used in high-current applications such as switching power supplies, DC-DC converters, and motor drivers.

In addition, the SRU2016-470Y has a wide operating temperature range of -55°C to +125°C. This allows the inductor to be used in automotive and aerospace applications. The inductor also has a high vibration resistance and is UL94V-0 certified, so it can be used in harsh environments.

The working principle of the SRU2016-470Y is based on Faraday\'s law of inductance. When an alternating current passes through the inductor, an electromagnetic field is generated. This induces a magnetic flux, which in turn creates a magnetic field. This magnetic field induces an electromotive force into the conductor, causing a current to flow. As the alternating current varies, the magnetic field changes, inducing a voltage drop in the inductor. This voltage drop is what creates the inductance of the inductor.

The SRU2016-470Y is a versatile inductor suitable for many applications. It provides high inductance, low DC resistance, and low EMI/RFI emissions, making it suitable for use in power supplies, RF, and microwave circuits. It is also highly robust, with a wide operating temperature range, vibration resistance, and UL94V-0 certification, making it suitable for harsh environments.
