PREMO, a developer of RFID automotive antennas, has launched a new 3D-coil with double functionality in both Low Frequency (125 kHz) and High Frequency applications (13.56 MHz). This innovative and extremely compact antenna has a high surface resistance NiZn ferrite core material (>10Mohm/mm) and medium initial permeability to work at high and low frequency. This provide a very stable performance in a wide range of temperature (-40ºC to +85ºC). The 2D1D15 Series, has the same format as 3DC15 (125kHz) transponder family and they can be provide with same mechanical performance: label, cap and/or foam.
The new 2D1D15 Series, provides 2D orthogonal coils designed for working at low frequency (standard 125 kHz) and a third orthogonal coil with this low frequency 2D which works at high frequency (standard 13.56 MHz). This Series is offered with 4.77 mH @125 kHz and 6 uH @13.56 MHz as standard inductance values. This antenna can be ordered with custom inductance parameters to fit the desired performance.
The surface mount device (SMD) configuration allows for easy integration in the automatic printed circuit board assembly process (lead-free reflow), avoiding damange to the winding wires when handled manually.
The 2D1D15 Series meets the AEC-Q-200, one of the most restrictive quality standards for electric components in automotive applications. The inductance and “Q” factor of the NFC coil has been measured at 13.56 MHz and are suitable for RFID applications with ISO15693 (vicinity: I-CODE) and ISO 14443 (proximity: MIFARE) interface.
