Fixed inductors are vital components used in a range of applications, such as radio frequency (RF) electronics, power supplies, and circuit boards. The SD20-6R2-R inductor is one such device, used for a variety of purposes.

SD20-6R2-Rs are smaller than other inductors, but have a wide inductance range, to cover most needs. They feature radial leads for use in circuit board designs and have a wide temperature range, making them suitable for a variety of applications. The SD20-6R2-R is primarily used as an inverter output inductor, although it is also a great choice for other applications, such as switching power supplies, DC-DC converters and EMI suppression.

These inductors offer several advantages over other, larger inductors. Firstly, they have a high current capacity – up to 2A RMS. Additionally, their compact size makes them ideal for prototyping and design. Finally, they can operate over a wide range of temperatures, making them suitable for both high- and low-temperature applications.

The SD20-6R2-R is manufactured using a magnetic material, such as Nickel-Iron (NiFe). This material enables the temperature stability and. robustness needed to be suitable for higher current capacity, as well as a wide temperature operation range.

The figure below shows the typical inductance versus current relationship of an SD20-6R2-R. As can be seen, the device maintains consistent inductance over a wide current range.

In operation, an SD20-6R2-R functions on the principle of electromagnetic induction. An electric current is applied to the winding of the inductor, creating a magnetic flux that induces a backlinking voltage in the winding. This voltage opposes the applied current and reduces the rate of change of the current. This effect is also known as “winding resistance”, as it resists current flow.

The SD20-6R2-R provides excellent thermal handling and robustness, while maintaining consistent inductance over a wide current range. It is ideal for applications such as inverter output inductors, DC-DC converters, EMI suppression, and switching power supplies. Due to its small size, it is also perfect for prototyping and design.
