With its high inductance values of 30 mH, 33 mH and 50 mH for the X, Y and Z axes, the new 3D transponder coil achieves very high sensitivity values of 25.5 mV/µT (X and Y axis) or 23.3 mV/µT (Z axis). This means that it currently offers the highest sensitivity values in a global product comparison, which are around 20 percent higher than those of predecessor products with comparable dimensions and inductance values.

Like the existing models for 125 kHz, the new 22 kHz coil is RoHS-compatible, has dimensions of only 11.5 x 12.5 x 3.6 mm3 and is mechanically very stable due to plastic extrusion-coating and laser-welded connections. This has been proven by the stringent drop tests prescribed for PEPS components, and these transponder coils are correspondingly qualified according to AEC-Q200.
