Premo NFC Antennas

SDTR1103-HF2 -SMD Drop Resistant Transponder Coil High Frequency

The SDTR1103-HF2 Series of Surface Mount ferrite wound inductor is the best solution when high electrical and mechanical performance is needed. Its length and cross sectional area are optimized to achieve the maximum sensitivity in the coil axis. The construction of the coil offer high mechanical performance due to the plastic base and ferrite laminate.

Key features:

  • High stability in temperature
  • Operation temperature (-40ºC to +85 ºC)
  • Good mechanical Performance
  • Drop test: more than 500 times x 1 meter
  • Tape & Reel: 3000pcs / reel

3DC1515-HF SMD 3D Coil 17.5×16.0x4.0 mm (3uH – 18uH)

In the last few years, Communication technology by Near Field Communications (NFC) has experienced a lot of improvements. PREMO enlarges its NFC product range with the new 3DC15-HF series. A combination of 3 single coils oriented in the 3 space axis. The new 3D coil from PREMO RFID offers the possibility of mounting a single component instead of three, thus reducing cost, saving PCB space and increasing the circuit reliability. Sensitivity, low profile and small size are the key of this RFID innovative component. Best choice for keyless entry systems the three tri-rectangular windings ensure optimum field sensing regardless position.


Key Features:

  • Size:17.5×16.0x4.0 mm
  • High drop test resistance (up to 500 times 1 m) due to a maximized pin area
  • High stability in temperature (-40ºC to +125ºC)
  • Isotropic version available
  • With cover cap or labelled
  • Taped & Reeled
  • Designed for 13,56MHz


ZC1003HF New High Sensitivity, Low profile NFC Z-axis Antenna

Due to its compact dimensions and low profile (height less than 3,1mm), the new ZC1003HF Series, based on NFC technology, is ideally suited for slim Smartphone designs by improving communication distance due to its high performance material and enhanced performance over metal ground planes or batteries.


The Near Field Communications (NFC) market is growing rapidly worldwide. Global shipments of Smartphons equipped with Near Field Communication (NFC) technology will surge by more than a factor of four from 2013 to 2018, reaching 1.2 billion units, according to IHS Technology.


One of the most popular NFC applications is cashless payment but it is increasingly being used in applications such as, physical access, driver identification, keyless entry systems, peer-to-peer file sharing, and credential storage and exchange.


In an effort to meet the growing demands for NFC antennas, PREMO has developed a new Z-axis SMD ferrite antenna suitable for signal reception/transmission at 13.56MHz.


The ZC1003HF series is a highly sensitive and compact solution (10mmx10mmx3.1mm) specifically designed for those NFC applications where component size is critical. This innovative antenna requires less board space compared with PCB printed loop antennas and offers up to 30% longer reading distances. Furthermore, this Z-axis coil’s design offers an outstanding electrical performance and mechanical robustness, providing an excellent reliability, as they are designed and validated with automotive standards.


The ZC1003HF series is offered with a 2.5uH inductance value and 13,56MHz operating frequency but can also be tailored according the customer’s specifications.


The ZC1003HF antenna includes a high performance NiZn ferrite core material (>106 Ohm•m) and low initial permeability to work at high frequency. It provides a very stable performance over a wide range of temperature (-40ºC to +100ºC). Additionally, the ZC1003HF series offers better performance over metal ground planes or batteries devices.


Its surface mount (SMD) configuration and tape and reel packaging configuration allows for easy integration into an automatic printed circuit board assembly process and avoiding handling of the piece that could damagethe very fine gauge coil wire.


The ZC1003HF can also be used in RFID applications with ISO15693 (vicinity: I-CODE), ISO 14443A&B (proximity: MIFARE) interface, ISO18092, and Felica.

The ZC1003HF Near Field Communication antenna has been designed to match NFC chipsets from among others AMS: AS3953.
