2.Functions

Flat Copper Wire Coil is used to manufacture insulated wires or windings in electrical products. Also known as winding wire. Electromagnetic wire must meet the needs of a variety of applications and manufacturing skills, the former including its shape, specifications,short and long-term work at high temperatures, and accept violent vibration in some occasions and centrifugal force at high speed,high voltage resistance to corona and breakdown, especially in the atmosphere of chemical corrosion resistance; The latter includes the need to experience stretching, bending and wear during winding and wiring, as well as swelling and corrosion during dipping and drying.

3.Applications

Flat Copper Wire Coil is mainly used in the fields of induction acceptance, prefocus, magnetic card, magnetic head, high current line separation, low voltage electrical appliances, industrial control, household appliances, car electronics, SMT mounting, mobile phones, wireless transceiver, electronic navigation device, power regulator, amplifier, supplier and filter.

4.Specificities

1. Superior high-frequency characteristics
--Low loss: there is no magnetic material core, no hysteresis loss and eddy current loss. Hysteresis loss arises from the energy consumption during repeated magnetization and demagnetization of the magnetic material in an alternating magnetic field, while eddy current loss is caused by the energy loss due to the induced currents generated in the core conductor by the alternating magnetic field. Hollow core inductors avoid these losses due to the absence of a magnetic core, making them particularly suitable for high frequency applications, such as RF circuits at the GHz level, to ensure efficient signal transmission and minimize energy wastage.

--No magnetic saturation: Magnetic materials can become magnetically saturated at high magnetic field strengths, resulting in a decrease in inductance and affecting circuit performance. Hollow core inductors use air as the magnetic medium, so there is no magnetic saturation, and even under high current or strong magnetic field environment, they can maintain stable inductance characteristics, which ensures stable operation of circuits in various working conditions, such as in high-frequency and high-power transmitting circuits, and maintains stable inductance performance.

2. Good linearity
--Low signal distortion: The inductance value of hollow inductor basically does not change with the size of the current, and it has good linearity characteristics. When dealing with alternating signals, it can ensure that the amplitude and phase relationship of the signal is accurate, and will not produce signal distortion due to the nonlinearity of the inductor. In the audio power amplifier, used in the processing of audio signals can ensure high-fidelity sound reproduction, to avoid sound distortion, noise and other problems.

3. Flexible design
--Strong customization: By changing the number of turns, wire diameter, winding method and shape, etc., the inductance value and current carrying capacity of hollow inductors can be flexibly adjusted. For example, the current carrying capacity can be increased by using multi-stranded wire winding, and the inductance value can be fine-tuned by changing the spacing of the windings. This high degree of design flexibility allows them to meet the needs of a wide variety of special circuits, whether it is a miniaturized portable device or a large industrial device with special circuits, all of which can be customized with hollow inductors to achieve specific functions.

-Variety of sizes: Hollow core inductors do not need to consider the limitations of core size and shape, and can be designed in a variety of sizes and shapes to meet the space requirements of actual application scenarios. From tiny chip type hollow core inductors for compact circuit boards to large customized hollow core inductors for high power industrial equipment applications, different space layout requirements can be met.

4. Good heat dissipation performance
--No core heat: Since there is no heat generated by core loss, the main heat source of Flat Hallow Inductor Coils during operation is the Joule heat generated by the winding resistance. Compared with magnetic core inductor, its heat dissipation burden is small. Moreover, air as a heat dissipation medium is conducive to the natural dispersion of heat without additional complex heat dissipation measures, which is advantageous in some application scenarios with high heat dissipation requirements but limited space, such as miniaturized wireless communication modules.
