Fixed inductors are essential components of modern electronic circuits, and they can be found in a wide variety of applications. In recent years, there has been an increasing demand for highly reliable and robust inductors that can handle extreme environmental conditions while offering superior performance. The SDR1307-4R7ML is a perfect example of such an inductor, combining superior performance with reliable operation.

The SDR1307-4R7ML is a robust fixed inductor with a rated operating temperature ranging from -30°C to +85°C. It is constructed of RoHS compliant materials and utilizes a 4.7mH inductance value. This specific model comes in four different winding types offering either through-hole or SMD installation options. The rated current of the SDR1307-4R7ML ranges from 0.9A up to 4A, depending on the specific winding option chosen.

The SDR1307-4R7ML is capable of handling high voltage transients up to 200V, and supports high current switching speeds of up to 900kHz. This makes the device ideal for use in motor control and power supply applications where high frequency load changes and high voltage transients are a concern. It is also well-suited for high power filters, dc-dc converters, and RF amplifiers.

The working principle behind the SDR1307-4R7ML is quite simple. It consists of a copper core that is wound with 1 or more layers of wire. This wire is insulated by a special varnish which prevents short circuits. When current is applied, a magnetic field is generated which induces an electromotive force (EMF) in the windings. This EMF is then converted into a voltage that can be used by the application.

The SDR1307-4R7ML is a reliable and robust fixed inductor that provides superior performance for a wide range of applications. Its robust construction and high operating temperature range make it an ideal choice for applications that demand reliable operation in extreme environments. Its ability to handle high current switching speeds and voltage transients make it well-suited for a range of motor control, power supply, filter, and RF amplifier applications.
