| Document 223-1 RFID Transponder Coils - 4308TC NOTE: This product has been replaced by the 4308RV series. The new series is footprint compatible and offers better read distances and an expanded temperature range. Coilcraft's family of antenna coils are rugged, high performance devices intended for RFID applications at 125 kHz. These low profile parts have an extended length that allows longer read ranges and higher sensitivity. The coil is constructed of ferrite laminated onto a ceramic base, which makes it more rugged and impact resistant than all-ferrite constructions. An encapsulated top ensures reliable pick and place operations. In addition to the standard models shown, Coilcraft can design transponder coils designed to operate at other frequencies.

When ordering, please specify packaging code: 4308TC-815XJLD Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (3000 parts per full reel). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter D instead. 2. Inductance and Q measured using Agilent/HP 4192A impedance analyzer. For recommended test procedures, contact Coilcraft. 3. Read distance measured using the KEELOQ(R) Transponder Evaluation Kit part number DM303005 from Microchip. Distance was recorded as the voltage across the resonant circuit dropped below 10 mV. 4. Matching capacitor value required for parallel resonant circuit operating at 125 kHz. 5. DCR measured on micro-ohmmeter. 6. SRF measured using Agilent/HP 8753D network analyzer. 7. Operating temperature range -40C to +85C. 8. Electrical specifications at 25C. See Qualification Standards section for environmental and test data. Specifications subject to change without notice. Please check our website for latest information.
