Prompted by new legislation in the US that requires new vehicles to be fitted with a low tyre pressure warning system as a safety device, TDK has developed its TPL series of transponder coils. The TPL series is ideal for automotive systems including tyre pressure monitoring systems, passive keyless entry devices and engine immobilisers.
The TPL transponder coils offer high reliability and durability provided by a full moulding, which protects the coil during assembly. The full moulding and flexible terminal ensure that the TPL series can withstand extreme bend and drop tests, and provide best in class shear force resistance. This makes the TPL series ideal for automotive systems that demand high performance.
TDK's expertise in manufacturing ferrite cores means that the TPL transponder coils have been designed to the highest quality and sensitivity, ensuring their reliability in safety applications such as tyre pressure monitoring. Each coil houses a ferrite core made from advanced magnetic materials and manufactured to an optimum design, following extensive magnetic field analysis and Spice simulation by TDK.
The TPL transponder coils demonstrate very stable electrical characteristics, due to the high quality of the ferrite core. The coils have a high self-resonance frequency made possible by TDK's special winding process, carried out during manufacturing. This ensures that the inductance characteristics of the coils remain stable. TDK has designed the TPL series using lead free ferrite, terminals and solder.
