Fixed inductors, commonly known as chokes, are components that are capable of blocking the AC current in the circuits while allowing the DC current to flow. The MMI303 is a family of fixed inductors, designed for various applications requiring power and current levels ranging from low to high wattage power supplies. As well as providing high efficiency, the MMI303 has a low DCR making it ideal for high-frequency applications.

The standard application of the MMI303 is mainly used for power conversion in AC/DC power supplies, ranging from those required by high-end PCs and modern telecommunications systems to SMPS, DC/DC converter and uninterruptible power supplies (UPS). The rapid response time of the MMI303 is well suited to high frequency conversion applications, including switched mode power supplies and inverters. Additionally, the use of the MMI303 as an inductor can be customized for various fast-start up and short-time load switching applications.

The working principle of the MMI303 is based on Faraday’s law of induction. An inductor consists of a coil of wire wound around a core material such as iron or ferrite. When an electric current passes through the wire, an electromagnetic field is generated in the core material, creating an inductance effect. This inductance has the ability to store energy in a magnetic field and then return that energy back into the circuit once the current is removed.

The MMI303 is built using low DCR foil and an optimized core material, providing higher quality and a lower profile final product. The MMI303 is designed to operate at higher frequencies than other standard inductors, making it suitable for today’s high-frequency applications. Additionally, the MMI303 also has the ability to reduce the power loss or power dissipation due to its thermally enhanced core design and improved heat dissipation.

The MMI303 is available in a variety of sizes and configurations, from a miniature version for portable and consumer electronic applications, to large-scale versions for industrial applications. Regardless of size, the MMI303 provides a low cost, high efficiency, and reliable solution for various AC/DC conversion applications. Furthermore, the MMI303 is RoHS compliant, making it an excellent choice for environmental and sustainability concerns.

Overall, the MMI303\'s high efficiency, low profile design, and high-frequency performance make them the perfect option for AC/DC power conversion needs. Whether utilized in consumer electronics, portable devices, or industrial systems, the MMI303 provides a reliable and efficient solution for various power conversion applications.
