  1. 1. RFID Transponder Inductors RFID Transponder Inductors Introduction An RFID system PREMO RFID Components is a leading RFID is a method of wireless data manufacturer in transponder inductances interchange by using an electro-magnetic for SMD assembly processes focused field as media. mainly on automotive market applications, The use of RFID in tracking and access animal identification and industrial- applications first appeared during the logistics applications. In 1995 PREMO 1980s; RFID quickly gained attention RFID Components launched the first because of its ability to track moving transponder inductor in SMD for the objects. automotive market. His strong bet for continuous development and innovation An RFID system always has two elements: leads PREMO RFID Components to -The transponder, which is located on the introduce in 1999 the first isotropic 3D object to be identified. coil for KES in the world and in 2003 a -The interrogator or reader, which, new chip-on-ferrite solution for animal ID. depending upon design and the Innovative products with the latest technology used, may be a read or available technologies and higher possible write/read device. quality incorporated to revolutionary designs make our competitive difference. The transponder (tag) normally consists on a coupling element and an electronic Most of transponders produced in PREMO microchip which processes the data RFID Components work at 125 kHz for transmitted and/or received in the automotive applications and at 134 kHz communication reader-transponder. for animal ID applications. 125-134 kHz A reader typically contains a radio belongs to the Low Frequency range for a frequency module (transmitter and common classification of transmission receiver), a control unit and an antenna. frequencies in RFID (Radio-Frequency PREMO RFID Components can supply Identification): both elements and design them in order -Low Frequency (30 kHz - 300 kHz). to achieve the maximum power -High Frequency/Radio Frequency (3 MHz transference. - 30 MHz). -Ultra High Frequency (300 MHz - 3 GHz). -Microwaves (>3GHz). 125 kHz is a suitable frequency for RFID applications classified into the worldwide ISM frequency ranges (Industrial-Scientific- Medical). In this catalogue you’ll find a broad range of standard transponder inductors for RFID applications to help you accomplish your electrical mechanical and functional targets. Besides, customized Transponder unit into a magnetic field generated by an products are designed and prototypes built antenna in our R&D department according to customer requirements for those products Reader sends out electromagnetic waves not fitting into the standard product design through an alternating current passing by because of special features needed or the reader antenna.

At present, some of the main uses of 125 kHz systems are: 125 kHz RFID systems operate by using inductive coupling. Specific absorption 1.

Therefore, long range systems need an auxiliary battery. In this application, transponder coil is required high sensitivity and high stability Low-frequency (LF: 125 - 134.2 kHz and in a wide range of temperature that usually 140 - 148.5 kHz) and high-frequency (HF: is -40 ºC up to +125 ºC. 13.56 MHz) RFID tags can be used globally without a license. It has been shown, that into adverse road conditions, tyre defects or their combination play an important role in road accidents and thus the use of an intelligent tyre/wheel system is a high potential of accident prevention. 31
  3. 3. RFID Transponder Inductors RFID Transponder Inductors immobilization, the vehicle sends a challenge to the transponder and verifies its response by operating with different crypto-algorithms. If communication protocol between the reader (generally an air coil located around the key slot) and the key transponder is correct, car’s ignition is released. Generally, electronic immobilizer and door locking system are integrated into the same transponder in the ignition key. These transponders are required to perform the same features than RKES application transponders. PREMO RFID offers a wide variety of transponders specially designed for TPMS applications. 2. Automotive RKES (Remote Keyless Entry System). Many vehicles are nowadays equipped with a Remote Keyless Entry System (RKE), typically including an encr ypted transponder and a controller chip (or an ASIC). When the transponder is detected inside the magnetic field generated by the reader antenna, the controller generates a rolling code that is being transmitted to the vehicle. Then, communication protocol process between the reader antenna and PREMO RFID offers a wide variety of transponders specially the key begins. The reader antenna is designed for RKES applications. located in the door-handler connected to the drive unit and generates the magnetic 4.

Transponders also have a much higher storage capacity than In this application, transponder is required: conventional barcodes. Therefore, -Very high sensitivity. additional information can be attached -Very high stability in the operating to objects to be tracked.

  4. 4. RFID Transponder Inductors RFID Transponder Inductors applications for automatic feeding and calculating productivity), transmission and coding procedures are provided by the 1996 ISO standards. Different populations of animals are tracked, controlled and identified with a transponder: from pets (cat and dogs), cows, salmons, insects. In this application, transponder can be placed under the animal’s skin – so called glass transponder - , in kind of ear-ring (ear tag), inside a rumen bolus or around the neck in a collar. Transponders sensitivity and reduced dimensions are the most valuable characteristics in this applications. 6. New revolutionary uses. Combined with sensors to monitor body functions, these devices can provide monitoring for patients. In general, any kind of identification can be performed so the number of different applications is unlimited. For instance, Mexico City police department has implanted approximately 170 of their police officers with the Verichip, to allow access to police databases and possibly track them in case of kidnapping. One disco Club in Barcelona uses an implantable Verichip to identify their VIP customers, who in turn use it to pay for drinks with discount. The closest future opens inf inite application possibilities for transponders technology. Current development lines are aimed to reduce size as well as to increase sensitivity and to enlarge reading distance. 33

  9. 9. TR1504 15x5x2 mm SMD Ferrite Transponder Inductor (7.20 mH – 0.29 mH) RFID Transponder Inductors Materials The TR1504 series is the large core volume alternative for Surface mountable low profile, ferrite wound transponder inductor.
