SMD isotropic antenna designed for NFC applications
The antenna has a high surface resistance NiZn ferrite core material (>10 Mohm/mm) and low initial permeability to work at high frequency. This provide a very stable performance in a wide range of temperature (-40 ºC to +85 ºC). This series has the same format as 3DC15 (125 kHz) 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 60 µH inductance values. Designers can use all previous inductance values independently or combine them to produce the standard inductance values of 1, 2, 3, 6 and 20 µH, connecting the 3 axes in parallel.
The SMD antenna is easily integrated into the automatic printed circuit board assembly process (lead-free reflow), avoiding handling of the piece that could damage its coil.
the company’s NFC antennas also include the SDTR1103-HF family. PREMO has recently enhanced This family has recently been enhanced with new inductance values from 1 to 20 µH.
The SDTR1103 and 3DC15 series meets AEC-Q-200 requirements (one of the most restrictive quality standards for electric components) in automotive applications — which also ensures performance of the component in applications for both domestic and industrial environments.
The Super Drop Test Resistance coil (SDTR1103-HF2) and 3DC15-HF (in its foam version) are especially suitable for applications which require high (drop-tests) requirements, like mobiles and key-fobs, etc.
The inductance and “Q” factor has been measured at 13.56 MHz and are suitable for RFID applications with ISO15693 (vicinity: I-CODE) and ISO 14443 (proximity: MIFARE) interfaces.
