Air coils can be used as current transformers, with the features of wide frequency band, small size, light weight. It's convenient for digital measurement and protection of microcomputers.

I, Applications of air coil

Air core coils are mainly used for induction receiving, focusing, magnetic cards, magnetic heads, high current inductors, low voltage electrical appliances, industrial control, household appliances, car electronics, SMT placement, mobile phones, wireless transceivers, electronic navigators, power conditioners, amplifiers, In electronic products or electronic accessories such as suppliers and filters.

II, The difference and connection between the inductance of the air coil and core coil

The magnetic permeability of the air-core coil is air permeability, and the relative magnetic permeability is 1(This is a constant). The core of the core coil is ferromagnetic, and its magnetic permeability is not a constant. It decreases as the magnetic flux density in the core increases, which means that the larger the magnetic density, the smaller the inductance.

III, We produce and design various air coils

electronic label coil; IC, ID card induction coil; QI wireless receiving coil; Solar swing coil; Fingerprint induction coil; Water meter coil; Special-shaped coil; Vibration motor coil; Horn coil; Card reader coil; High quality miniature SMD coil, etc.

We also manufacture all kinds high frequency transformers, LAN transformers, inductors, EMI filters and other electronic components. Any request, please be free to contact us, we will give you fast reply.
