December 14, 2011 - Premo releases 3DC15-HF 3D-coil isotropic magnetic antenna for NFC applications (13.56MHz). In the last few years, Communication technology by Near Field Communications (NFC) has experienced a lot of improvements. New tablets, smart phones, etc, have been announced with NFC functionality. The antenna has a high surface resistance NiZn ferrite core material (>10Mohm/mm) and low initial permeability to work at high frequency.
This provide a very stable performance in a wide range of temperature (-40ºC to +85ºC). This series has the same format as 3DC15 (125kHz) transponder family and they can be provide with same mechanical performance: label, cap and/or foam. 3DC15-HF is offered with 3, 6, 9, 18 and 60uH inductance values. A user can use all previous inductance value independent or combine them to produce the standard inductance values of 1, 2, 3, 6 and 20uH connecting the 3 axes in parallel. Its Surface Mounting Device (SMD) configuration allows an easy integration in an automatic printed circuit board assembly process (lead-free reflow), avoiding handling of the piece that could damage winding wire of the piece.
