SMD antenna for near-field communications
Premo
SDTR1103-HF series
Premo has expanded its SDTR1103 offering with the SDTR1103-HF series, an SMD antenna for signal reception at 2MHz and/or 13.56MHz Tx/Rx for near-field communications applications.
The antenna has a high surface resistance NiZn ferrite core material (>10Mohm/mm) and low permeability to work at high frequencies.
This is said to provide a stable performance in a temperature range of -40C to +85C.
The series has the same format as 125kHz transponders, the SDTR1103 range.
SDTR1103-HF is offered with 290uH/2MHz and 20uH/13.56MHz inductance values.
Its surface mounting device (SMD) configuration allows an easy integration in an automatic printed circuit board (PCB) assembly process, avoiding handling of the piece that could damage winding wire of the piece.
This Super Drop Test Resistance coil is said to be particularly suitable for applications that require high (drop-tests) requirements, such as mobiles and key fobs.
SDTR1103-HF2-0020K is tuned at 13,56MHz and suitable for RFID applications with ISO15693 (vicinity: I-CODE) and ISO 14443 (proximity: MIFARE) interface.
