Dual Function Antenna from Ineltek Integrates NFC and LF Comms

Aldermaston, UK: February 8th, 2016 – Ineltek UK, the UK and Ireland arm of Germany’s largest independent semiconductor distributor announces the release of the Premo 2D1D15 antenna series with dual functionality for both Low Frequency (125 kHz) and NFC High Frequency applications (13.56MHz) all in one package.


Premo’s 2D1D15 Series provides 2D orthogonal coils designed at the standard 125kHz LF frequency and a third orthogonal coil to operate at the standard 13.56MHz. 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. Providing very stable performance from -40C to +85C, the 2D1D15 Series is available with 4.77mH @125 kHz and 6uH @13.56 MHz standard inductance.


  • 5mm x 16.0mm x 4.0mm
  • High drop test resistance (up to 500 times from 1 m) due to a maximized pin area
  • High stability in temperature (-40C to +85C)
  • Designed for 125kHz, 134kHz and 13.56 MHz

2D1D15 NFC Antenna

The inductance and “Q” factor of the NFC coil has been measured at 13.56MHz and is suitable for RFID applications with ISO15693 (vicinity: I-CODE) and ISO 14443 (proximity: MIFARE) interfaces.


Ineltek’s design support specialists can consult with client engineering teams to define custom inductance parameters to fit specific requirements and then work Premo to develop the exact solution needed to bring new products to market. Contact Ineltek sales for further information or to arrange to evaluate samples.
