Inductors are essential components in any circuitry, from power to signal circuits, and they are used in many different types of electronics. In particular, fixed inductors, as the name suggests, have a fixed amount of inductance and are typically used in circuits involving radio frequencies. The FL3215T-220K is a fixed inductor typically used in power supply circuits.

A basic working principle of an inductor is the induction of electromagnetic fields when AC or DC current passes through it. This induces a magnetic field around the conductive coil that confines the current and acts as a closed loop. Unlike a capacitor, which stores electric charges, an inductor stores energy as it passes through its windings. When the current is interrupted, the stored energy is released providing power to the loads the inductor is connected to. This current interruption creates a voltage spike that can be damaging to the electronic components the inductor is connected to.

The FL3215T-220K is designed specifically for use in power supplies and provides significant performance enhancements over other inductor varieties. Comprised of a multiple straight line windings around a cylindrical core, this fixed inductor can reach an inductance of between 0.176uH and 0.225uH. It’s also designed to operate in a wide temperature range from -55oC to +125oC, making it suitable for use in almost any environment.

The inductor is also designed for high-performance, allowing switching frequencies up to 500KHz. Thanks to its durable construction, it’s suitable for use in extreme environments and receives adequate shielding against EMI and RFI interference. Also, due to its large footprint, the FL3215T-220K can sustain higher sustained currents compared to other inductors of similar size, allowing it to accommodate more power while maintaining low heat sinking.

When it comes to its applications, the FL3215T-220K is ideal for point-of-load (POL) power supplies, SMPS, DC/DC converters, mobile phone chargers, and LED drivers. Its ability to withstand extreme temperatures and its streamlined construction allows for increased power efficiency and high switching frequency capabilities, making it perfect for applications that require small form factor and/or high accuracy. In addition, its extensive operating temperature range makes it suitable for use in a wide array of industries including medical, automotive, automotive, and embedded platforms.

Overall, the FL3215T-220K is an excellent choice for high-performance applications, from small form factor devices to medical-grade power supplies. Its wide temperature range, high frequency operation, and low-heat sinking capabilities make it a perfect choice for many applications that require power supplies that can withstand the rigors of extreme temperatures or conditions. In addition, its small form factor and high-level shielding make it ideal for long-term operation and reliable performance even in highly-radiated and highly-conductive environments.
