MP A2 Coil Qi Transmitter Coil Supplier - JHCOIL
If you want make an 15W wireless charger with QI certification. MP-A2 coil should be good option for your design and also recommended by WPC for EPP certification.
According to WPC standard, the MP-A2 Coil is of the wire-wound type, and consists of no. 17 AWG litz wire having 105 strands of no. 40 AWG (0.08 mm diameter), or equivalent. The inner size of it is 19mm*19mm, 10 turns of coil winding. The inductance with ferrite is 10.0±10%μH.
Some KNOWLEDGE ABOUT Wireless Charging Design
We Are Committed to Wireles Charging Coil Production, here Belows check some Knowledge about wireless charging
JHCOILS: No magnet can exist in a circle with a radius of 35mm from center of coil module.
JHCOILS: Both single coil and multiple coils can be used in wireless charging EPP certification. The design types of EPP single coil include MP-A1, MP-A2, MP-A3, MP-A4, MP-A5, MP-A6, MP-A7, MP-A8, MP-A9 and MP-A10.
mp a2 coil with slot
JHCOILS: This is OK!
JHCOILS: No requirements for flame retardancy. However, there are requirements for the measures to be taken for the high temperature generated by foreign matters. Otherwise, the high temperature cannot be generated during the work. For example, the product needs cooling measures after the high temperature is generated.

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.
