Z Axis RFID Coil

RoHS compliant
The PA6512-AE z-axis coil is optimized for 13.56 MHz NFC/RFID tag applications and requires 85% less board space compared to antennas designed for a PCB, yet still has 50% of the read distance.
  • Optimized for use for the Z axis in Near Field Communications systems.
  • Evaluation was done using the STMicroelectronics CR95HF NFC Transceiver Reference boardwith the PA6512 connected to the STMicroelectronics M24LRxxE Dynamic NFC/RFID Tag.
  • Requires 85% less board space (123 mm2 vs 800 mm2) compared with antennas designed for a PCB yet still has approximately 50% of the read distance.

  1. When ordering, please specify packaging code: e.g. PA6512-AED
  2. Inductance measured at 100 kHz using Agilent/HP 4284A impedance analyzer or equivalent.
  3. Read distance measured using the ST Microelectronics CR95HF RF transceiver demo board.
  4. DCR measured at 25°C on a micro-ohmmeter using a Keithley 580 micro-ohmmeter or equivalent. For other operating temperatures, use this DCR at Temperature calculator


  • Tin over nickel over phos bronze


  • D = 13″ machine-ready reel. EIA-481 embossed plastic tape (1000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
  • B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to D.
