Fixed Inductors

Fixed inductors, also known as chokes, coils, or reactors, are utilized in electrical power systems to supply inductance. Inductors are vital components in power electronics applications, most commonly in the form of buck-boost or DC-DC converters, as they are used to filter out ripple current within a power conversion system. In most cases, a fixed inductor is composed of a short-circuited winding formed of a wire with a core as its base. The 77F150K is a fixed inductor that is capable of providing up to 150A of current, with a nominal inductance of 4.7µH and a saturation current of 200A.

The 77F150K is composed of two winding layers. The outer layer is a simulated DC winding and acts as a compensation coil that helps reduce the total equivalent series resistor (ESR) of the inductor. The inner layer is the actual working winding, which is designed to be short-circuited and filled with ferrite, providing a larger inductance value than what is achievable by winding a single coil alone. The combined effect of the two windings creates a large ferromagnetic impedance, giving the 77F150K a high current rating of up to 150A.

The 77F150K is ideal for use in applications such as DC-to-DC power supplies, high-frequency switching converters, server power supplies, lithium battery protection circuits, VCO or PLL applications, or as a noise-suppressing filter. It utilizes low-profile power inductors with excellent power handling capabilities and low DCR values that enable high current operation. The product also has a wide operating temperature range of -40°C to +125°C, making it suitable for use in many industrial applications.

The 77F150K has several advantages over traditional inductors, making it an attractive choice for use in industrial power electronics applications. It has a high-current rating and low DCR values that enable robust operation with minimal heat dissipation during high-current applications. Additionally, the product has excellent power handling capabilities and a wide operating temperature range. Finally, the 77F150K utilizes a unique winding design with both DC and AC simulated windings to reduce total ESR.

In summary, the 77F150K is an ideal choice for high-current DC-to-DC power conversion applications due to its low DCR, high-current capability, excellent power handling capabilities, and wide operating temperature range. It utilizes a unique winding design to reduce total ESR and is capable of providing up to 150A of current. The 77F150K is an excellent choice for various industrial applications due to its superior performance and reliability.
