Inductive reactance
The size of the blocking effect of inductance coil on AC current is called inductance XL, and the unit is Ohm. Its relation with inductance L and AC frequency f is XL = 2 π FL
Quality factor
Quality factor Q is a physical quantity indicating the coil quality. Q is the ratio of inductive reactance XL to its equivalent resistance, that is, q = XL / R.
The higher the Q value of the coil, the smaller the loss of the loop. 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 shield or iron core, and the influence of the skin effect of high frequency. The Q value of the coil is usually tens to hundreds.
distributed capacitance
The capacitance between turns of coil, between coil and shield, between coil and substrate is called distributed capacitance. The existence of the distributed capacitance makes the Q value of the coil decrease and the stability become worse, so the smaller the distributed capacitance of the coil, the better.

1. Application of patch coil: it is widely used in common mode filter, multi frequency transformer, impedance transformer, balanced and unbalanced conversion transformer, EMI noise suppression of electronic equipment, USB line of personal computer and peripheral equipment, LCD panel, low voltage differential signal, remote control key of automobile, etc.
2. Fixed inductance coil includes: loop coil, choke coil, common mode coil, ferrite bead, power inductor, with patch type and pin type to choose from. It is widely used in network, telecommunication, computer, AC power supply and peripheral equipment.
3. Characteristics and application of high current surface mount power inductor in closed magnetic circuit: ideal DC-DC conversion inductor, high power, high saturation inductor, small DC resistance, suitable for high current, with or in combination with roller packaging for automatic surface installation, applied to video recorder power supply, video recorder power supply, LCD TV, laptop, office automation equipment, mobile communication Communication equipment, DC / DC converter, etc.
4. Use of radio frequency inductor: widely used in mobile phone, VCO, TCXO circuit and radio frequency transceiver module, global positioning system, wireless network, Bluetooth module, communication equipment, LCD TV, camera, notebook computer, inkjet printer, photocopier, display monitor, game machine, color TV, video recorder, CD player, camera, digital camera, car electric Sub products, etc.
Magnetic core
The inductance of the coil depends on whether there is a core or not. Inserting ferrite core into the air core coil can increase the inductance and improve the quality of the coil.
Copper core coil: copper core coil is widely used in the ultra short wave range. The position of the copper core coil is rotated to change the inductance, which is convenient and durable.
Inductance
The inductance L represents the inherent characteristics of the coil, independent of the current. In addition to the special inductance coil (color coded inductance), the inductance is generally not specially marked on the coil, but marked with a specific name.
Inductive reactance
The size of the blocking effect of inductance coil on AC current is called inductance XL, and the unit is Ohm. Its relation with inductance L and AC frequency f is XL = 2 π FL
