H - type inductance has the characteristic that the general inductance does not have: its characteristic lies in the core two ends each has the circular magnetic disc, its cross section is a body h - type.I-type inductance not only simplifies the winding process, but also improves the coupling between magnetic core and coil, which can save the use of copper wire.
With its own excellent characteristics, the i-inductor is widely used, i-inductor is often used in inkjet printers, photocopiers, display monitors, broadband data machines, game consoles, color TV, video cameras, video cameras, microwave ovens, lighting equipment, automotive electronics and other products.
In order to make the i-inductance play an effective role, the following matters should be paid attention to in the use process:
1. The use of the inductor: moisture and dry, the high and low ambient temperature, high frequency or low frequency environment, will make the inductor show different characteristics.
2. Frequency characteristics of inductance: at low frequency, inductance generally presents inductance characteristics, i.e. only energy storage and high frequency filter characteristics.At high frequencies, however, its impedance characteristics are apparent.There is energy consumption and heating, perceptual effect reduction and other phenomena.
3. The maximum current and corresponding temperature rise shall be considered when designing inductance.
4. When using magnetic rings instead, materials with corresponding AL values should be found.
5. The commonly used wire is enameled wire, gauze wire or bare wire, and the most suitable wire warp should be calculated.
