As part of an antenna module for two-way smart key systems for vehicles, a variety is used and six to nine are used per vehicle.
Materials(Mn-Zn Ferrite) : SM-23T , SM-43T
Required characteristics : Stable inductance between -40℃ ~ 80℃.
Operating frequency : 125kHz or 135kHz
Core Shape : Bar type
Winding : Direct or bobbin type
It will wind coils around the fair core and make antenna modules through POTING, which will be mounted in locations such as 4DOOR and trunk console boxes on vehicles.
