3D transponder coils for automotive PEPS systems
With the introduction of a new type that features an operating frequency of 22kHz, TDK has extended its B82453C*A* series of 3D transponder coils. The new component (B82453C0335A022) complements the existing spectrum designed for a frequency of 125kHz and is suitable for automotive passive entry passive start (PEPS) and other access systems based on the lower frequency.
The new 3D transponder coil also offers high inductance values of 30, 33 and 55mH, respectively, for the x-, y- and z-axes. This results in high sensitivity values of 25.5mV/μT for the x- and y-axes, and 23.3mV/μT for the z-axis.
The company claims that these are the world's highest sensitivity values for 3D transponder coils and are about 20% higher than those of existing products with comparable dimensions and inductance values.
Like the existing types for 125kHz, the new 22kHz coil is RoHS-compatible and has dimensions of 11.5x12.5x3.6mm. Moreover, thanks to its plastic overmolding and laser-welded connections the component is mechanically stable. This has been proven in the severe drop tests prescribed for PEPS components. Accordingly, these transponder coils are qualified to AEC-Q200.
Applications:
- Automotive PEPS systems and other access systems
Key features:
- High sensitivity of 25.5mV/μT (x- and y-axes), 23.3mV/μT (z-axis)
- Dimensions of only 11.5x12.5x3.6mm
- Very high mechanical stability
- Qualified to AEC-Q200.
