TDK EPCOS Compact Z transponder coils are designed for passive entry, passive start (PEPS) car access systems.
With dimensions of 7.7 x 7.4 x 2.65 mm, the components are compact and feature a low insertion height. The B82451L*E402 series comprises seven transponder coils covering an inductance range from 1.0 to 10.0 mH. Depending on the type, the transponder coils feature a sensitivity of between 7 and 23 mV/µT at 125 kHz. The Q factor of the new components is between 50 and 58.
The injection-moulded plastic baseplate and laser-welded connections of the winding ensure that the coils are robust. The new components are also qualified according to AEC-Q200.
The product can be combined 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 x 3.5 mm and 8 x 2.7 mm respectively, these components are also compact. Using three discrete transponder coils offers flexibility of design and can save space on the PCB. All coils are RoHS compatible.
