Epcos - Inductor range expanded to include automotive transponder coils

With its newly developed transponder series, Epcos has expanded its broad range of inductors with a series of high-performance and robust products.

In addition to their 'outstanding' electrical properties, the components are distinguished by their high mechanical strength, making them ideal for demanding applications such as immobilizers and tyre pressure monitoring systems (TPMS). For the immobilizer, the coils are incorporated in the car key and in the TPMS, they are directly in the wheel, where they are exposed to high mechanical and dynamic stresses.

This extrusion-coated series designated B82450A was developed in close cooperation with the automotive industry and has significant stability advantages over competitor products. Their automated and flexible, manufacture also allows a rapid response to customer-specific demands. Apart from these two applications in automotive electronics, the coils are suited to other application areas that also require high mechanical ruggedness, says the company.

The transponder coils are designed for a frequency of 125kHz and can be operated in the temperature range from -40C to +125C. They are RoHS-compatible, suitable for lead-free reflow soldering to JEDEC J-STD-020C and can be processed with automatic SMD placement systems.
