Fixed inductors are passive components that play an important role in electrical circuits. They store energy in a magnetic field when power is applied, and then release it when the current is removed. Fixed inductors such as the SRP4012-R47M are specifically designed to be reliable and efficient in electronics applications such as power supplies, high-end audio equipment and motor control.

SRP4012-R47M, or a surface mount power inductor, is an ideal device for a wide range of power electronic applications including switching power supplies such as DC/DC converters, or various kinds of battery chargers. It is characterized by low DCR (direct current resistance) and low current noise. The SRP4012-R47M is available in multiple inductance values, and is compatible with lead-free reflow soldering processes.

The core of the SRP4012-R47M is made of ferrite, a non-conducting material, which makes it ideal for applications that require high currents. The coil winding consists of enameled copper wire which is then covered with polyurethane to increase insulation and protect the device against short circuits. The device also features an electro-plated nickel-containing layer on the surface which improves solderability and therefore enhances assembly efficiency. This type of inductor is also resistant to high temperatures and humidity.

The working principle of the SRP4012-R47M is based on the principle of inductance. When a current is applied to the coil it creates a magnetic field that stores energy. Depending on the value of the inductor, the stored energy in the form of a magnetic field can be released gradually or instantaneously.

The SRP4012-R47M is designed to withstand high temperatures and high currents, making it an ideal device for applications such as power supplies, high-end audio equipment and motor control. The device is also suitable for use in a wide range of power electronic applications such as DC/DC converters and battery chargers.

In summary, SRP4012-R47M is a versatile and reliable inductor designed for electronics applications. Its core is made of a non-conductive material and its coil is insulated by polyurethane. It is fully compatible with lead-free reflow soldering and can withstand temperatures up to 125°C. The device has low DCR and very low current noise and can be used in high current applications. The working principle is based on the principle of inductance, which allows the device to store energy and then slowly or quickly release it when the current is removed.
