Fixed inductors, often referred to as chokes, is a type of inductor with a fixed inductance and QR code value. Commonly used in power supplies and RF circuits, fixed inductors are often required to maintain stability and consistent output voltage. The PM20-1R2K is a series of fixed inductor manufactured by Ferro Solutions, and it offers a wide range of applications due to its stability and reliability.

The PM20-1R2K is classified into two categories based on their inductance values – 0.5uH and 0.1uH. These two inductance values offer two distinct levels of power: lower frequencies and higher frequencies. The 0.5uH inductor is designed to handle frequencies up to 100kHz, while the 0.1uH inductor can handle frequencies between 200kHz and 250kHz. Having this wide range of power allows the PM20-1R2K to be suitable for various applications including high-end audio applications, switching power supplies, large motor drives, and RF circuits.

The PM20-1R2K is housed in a ferrite core molded plastic casing that is designed to be resistant to vibration and ensure proper heat dissipation. This makes it an ideal solution for automotive applications where the environment is often dynamic and harsh. The casing is also designed to prevent oxidation, which can effectively increase the life of the part. Additionally, the part is designed to be cost-effective and UL certified.

The inductance value of the PM20-1R2K is determined by the ratio of turns in the inductor and the core material. By operating the inductor in a desirably ideal state, the ratio can be manipulated to achieve the desired inductance value. This is known as the “ratio of turn and magnetic material” technique, which ensures that the PM20-1R2K inductor is properly operating regardless of the application. The low temperature coefficient also ensures that its performance is consistent under varying temperature conditions.

The PM20-1R2K provides several advantages over conventional chokes, including higher efficiency, reliability, and improved performance. The improved efficiency of the inductor reduces power losses, which can help manufacturers reduce costs. The improved performance and reliability of this part also makes it suitable for use in mission-critical applications, such as medical and aerospace. Additionally, the component’s low temperature coefficient ensures a consistent and stable output even under varying temperatures.

When selecting a fixed inductor for a specific application, the PM20-1R2K should be considered as an excellent alternative to traditional chokes. The wide range of application fields, exceptional performance, and improved reliability offered by this series make it ideal for high-end audio, large motor drives, and RF circuits.
