EPCOS is now offering automotive electronics developers a sample kit with transponder coils. The types with dimensions of 7.8 x 2.7 x 2.7 mm3 and 11.4 x 3.5 x 3.5 mm3 are designed for polarization in the x-y coordinates (B82450A* series). They cover inductances of between 1.0 and 7.0 mH. These transponder coils have a sensitivity of between 10 and 51 mV/µT.
A type with dimensions of 7.7 x 7.7 x 2.65 mm3 is contained for polarization in the z coordinate (B82451N* series).
The transponder coils can be used for non-contacting tire pressure monitoring systems, immobilizers as well as passive locking and starting systems in motor vehicles. These rugged inductors are designed for a frequency of 125 kHz and can be operated in a temperature range from -40 to +125 °C. They are RoHS-compatible, suited for lead-free reflow soldering to
JEDEC J-STD 020C and can be processed with SMD automatic placement systems.
