TDK B82453C*A* 3D Transponder Coils

B82453C*A* 3D transponder coils

A new series of 3D transponder coils with a high sensitivity level is especially well suited for passive entry passive start (PEPS) and other access systems. Measuring just 11.5 mm x 12.5 mm x 3.6 mm, the B82453C*A* series features six types of 3D transponder coils that offer sensitivity levels from 45 mV/μT to 83 mV/μT and inductance values from 4.75 mH to 13.2 mH. The center frequency is at 125 kHz. Thanks to the optimized core geometry of the new 3D transponder coils, their sensitivity levels are about 20 percent higher than that of predecessor or competitor components with comparable geometries and inductance values. This enables the wake-up function of PEPS in vehicles applications to be activated at greater distances.

The RoHS-compatible 3D transponder coils have a robust overmolded casing and the terminals of the windings are laser-welded. As a result, they feature very high mechanical stability, as is proven by the severe drop tests required for PEPS applications. Accordingly, the new transponder coils are qualified to AEC-Q200.
