    High Frequencies RF SMD Power Inductors Flat Top Air Core Chip Coil 3.85nF 1.6A Round For Surface Mounting


    High Frequencies RF SMD Power Inductors Flat Top Air Core Chip Coil 3.85nF 1.6A Round For Surface Mounting


    General


    Aolittel's ultra-miniature single layer coil has two advantages. Firstly, like all air core coils, it is free from iron losses and the non-linearity. Secondly, single layer coils have the additional advantage of low self-capacitance and thus high self-resonant frequency. Air Coils is known as "Spring Coils". Aolittel manufactures all types of air coils inductors.

    Single layer air coil windings formula and the Q factor can be referred at Equations of Single Layer Air Coil Winding Formula and Methods.

    TRAD's inductance is unaffected by the current it carries. This contrasts with the situation with coils using ferromagnetic cores whose inductance tends to reach a peak at moderate field strengths before dropping towards zero as saturation approaches. (TRAD) series features better Q-factor, greater efficiency, greater power handling, Highest possible SRFs, and less distortion.

    Aolittel RF chip inductor non-flat top air core inductor conforms to the RoHS directive and Lead-free. Application of specific designs also available including different inductance values and Q specifications adjusted to frequency requirements.

    The Advantages of an Air Core Inductor (coils)


    Its inductance is unaffected by the current it carries. This contrasts with the situation with coils using ferromagnetic cores whose inductance tends to reach a peak at moderate field strengths before dropping towards zero as saturation approaches. Sometimes non-linearity in the magnetization curve can be tolerated; for example in switching converters. In circuits such as audio cross over networks in Hi-Fi speaker systems you must avoid distortion; then you need an air coil. Most radio transmitters rely on air coils to prevent the production of harmonics.

    Air coils are also free of the 'iron losses' which affect ferromagnetic cores. As frequency is increased this advantage becomes progressively more important. You obtain better Q-factor, greater efficiency, greater power handling, and less distortion.

    Lastly, air coils can be designed to perform at frequencies as high as 1 Ghz. Most ferromagnetic cores tend to be rather lossy above 100 MHz.

    The Flat Top Air Core AM Inductors are lead-free and RoHS compliant. Please contact us for details with your specific needs.
