The series 3DC09AOI features three orthogonal coils, side metallization for automatic optical inspection during the soldering process. The pads have a gold finishing for excellent connectivity. The device measures 10.5 x 9.5 x 3 mm and is highly stable with its windings fully protected by a polymer matrix. It supports a double lead free reflow (270 °C at peak) and operates in the -40°C to 85°C temperature range.
The antenna is offered with a standard inductance value of 14mH with sensitivity greater than 9mVpp/App/m at 20 kHz and a Q factor of 6. The antenna is AEC-Q-200 qualified.
