Depending on the type, the transponder coils feature a sensitivity of between 7mV/µT and 23mV/µT at 125kHz. The Q factor of the new components is between 50-58.
The injection-moulded plastic baseplate and laser-welded connections of the winding ensure that the Z transponder coils are extremely robust. The new components are also qualified according to AEC-Q200.
Moreover, the Z transponder coils can be combined very well with the EPCOS B82450A*A* and B82450A*E* transponder coil series for the x- and y-axes. With their footprints of just 11.4×3.5mm and 8×2.7mm, respectively, these components are also very compact.
Solutions using three discrete transponder coils offer high flexibility of design and can save space on the PCB. A design combining the new Z transponder coil with two 8-mm X and Y transponder coils, for example, needs an area of just 100mm². All EPCOS transponder coils are RoHS compatible.
