Fixed inductors, also known as chokes, are wound inductors that are typically used for power supply filtering, output coupling, and bias applications. The SD14-1R5-R is an example of a fixed inductor that is used for these applications.

Features

The SD14-1R5-R fixed inductor is a surface mount device with a low DCR of 1.5 mΩ. It is available in a wide variety of packages which include 1210, 1211, 1812, 1813, and other sizes. This part is also available with high temperature options, such as a 150°C to +180°C range, and has a current rating of up to 3.5 amps.

Applications

The SD14-1R5-R fixed inductor is a versatile part suitable for a wide range of applications. It is designed to reduce ripple and noise in power supply filtering to provide improved system noise reduction. It is also used in filter/bypass applications including motor drive, telecoms, power conversion, and power conditioning. In addition, the SD14-1R5-R can be used in DC-DC converters, noise suppression, RFI/EMI filtering, output coupling, and bias applications.

Working Principle

The working principle of a fixed inductor is based on Faraday\'s law of induction. An inductor consists of a coil of wire and a magnetic core. When a current flows through the coil, a magnetic field is created. This magnetic field will interact with the core and generate an opposing voltage. This creates a voltage drop and a high impedance, making the inductor an ideal part for reducing ripple and noise in power supplies.

The SD14-1R5-R fixed inductor utilizes this working principle to reduce noise in power supplies. This part is designed to have a lower DCR than other inductors, reducing the power losses in the circuit. The wide temperature range allows for the inductor to be used in high temperature applications, up to +180°C. The SD14-1R5-R also has an adjustable current rating to meet the needs of different applications.

Conclusion

The SD14-1R5-R fixed inductor is an ideal part for noise reduction and ripple in power supplies. This part can also be used in filter/bypass applications, DC-DC converters, and output coupling. Its low DCR, wide temperature range, and adjustable current rating make the SD14-1R5-R an ideal part for these applications.
