   GIS combined coils What are the classifications of GIS combined coils?


  Classification by inductance form: fixed inductance, variable inductance.


  Classification by conductive magnet characteristics: air core coil, iron core coil, iron core coil, copper core coil.


  Classification by operating characteristics, including antenna coils, vibrating coils, chokes, trap coils, deflection coils, etc.


  Classification by winding structure: single-layer coil, multilayer coil, honeycomb coil.

        GIS combined coils

  The conductor L of the GIS combined coil represents the inherent characteristics of the coil itself and is independent of the current magnitude. Except for special inductor coils (color-coded inductors), inductors are usually not displayed on the coil with a specific name.


  What are the parameters of the GIS combined coil?


  The magnitude of the effect of an inductor coil on AC current interference is called inductive reactance XL, with the unit being ohms.


  What is the quality factor of the GIS combined coil?


  The quality factor Q of a GIS combined coil is a physical quantity that represents the quality of the coil. Q is the ratio of XL to the corresponding resistance, i.e., Q=XL/R.


  The higher the Q value of the GIS combined coil, the smaller the loss in the circuit. The Q value of the coil is related to the DC resistance of the conductor, the dielectric loss of the frame, the loss caused by the shielding film or iron core, the influence of the high-frequency skin effect, etc. The Q value of the coil is usually between tens and hundreds.


  Distributed capacitance


  The capacitance that exists between the turns of the GIS combined coil, between the coil and the shield, and between the coil and the board is called distributed capacitance. The existence of distributed capacitance reduces the Q value of the coil and reduces stability, so the smaller the distributed capacitance of the coil, the better.


  What are the various uses of GIS combined coils?


  1. Uses of GIS combined coils: Widely used in common-mode filters, multi-frequency transformers, impedance transformers, balanced and unbalanced transformers, USB lines for personal computers and peripherals, LCD panels, low-voltage differential signals, car remote keys, etc.


  2. Fixed inductor coils can be selected from toroidal coils, chip coils, common-mode coils, ferrite beads, power inductors, surface mount and pin types. Widely used in networks, communications, computers, AC power supplies, and peripherals.


  3. Characteristics and applications of closed magnetic circuit high-current surface mount power inductors: Ideal DC-DC converter inductors, high power, high saturation inductance, low DC resistance, suitable for high current, can be automatically surface mounted or parallel reel packaged, suitable for regenerative power supplies, LCD TVs, and laptops.


  4. GIS combined coils Wireless transmission applications: mobile phones, circuits and wireless transceiver modules, global positioning systems, wireless networks, Bluetooth modules, communication equipment, flat-panel TVs, cameras, laptops, inkjet printers, copiers, display monitors, game consoles, color TVs, etc.
