Some KNOWLEDGE ABOUT a11 COIL
We Are Committed to Wireles Charging Coil Production, here Belows check some Knowledge about A11 Transmitter Coil.
According to WPC standard, The Primary A11 Coil is of the wire-wound type, and consists of no. 17 AWG (1.15 mm diameter) type 2 litz wire having 105 strands of no. 40 AWG (0.08 mm diameter), or equivalent. In general, the turns of A11 coil is about 10 turns. the inductance of A11 Coil is 6.3±10%μH(with ferrite shielding)
The structure of A11 Coil
The A11 wireless Charging coil Shielding should be Ni-Zn or Mn-Zn ferrite and should be at least 0.5 mm thick(In general thickness is 1.0mm). The Shielding extends to at least 2 mm beyond the outer diameter of the Primary Coil. The below size of A11 coil ferrite sheet is available from us:
- Round Ferrite Sheet: 50mm*1.0mm
- G50 Ferrite Sheet: 50mm*5mm*1.0mm
- Square Ferrite Sheet: 50mm*50mm*1.0mm

Wireless Power Charging
Wireless Power Charging is becoming more and more common in our daily life,which is widely used in like smart phones,smart wear, car charger,bluetooth,laptop,wallent,etc.With this pace of technological growth we can certainly forcast in the future that we will enter intowireless charging life style without limited in the consumer market.With more and more wireless charging coils and control circuit chips manufacturers & designer hard work,wireless charging module can meet not only for low power standard like 5W,it can also support high power standard up to 100W. Technical Summary Higher coupling, lower physical distance between transmitter and receiver higher turns ratio will ensure higher voltage at receiver and so higher VIN. More turns,higher inductance & resistance. The thinner wire diameter,the higher inductance & lower resistance.
