RFID Transponder Coils – 4308RV
Coilcraft’s 4308RV antenna coils are high performance devices intended for RFID applications at 125 kHz.
These low profile parts have an extended length that allows longer read ranges. An encapsulated top ensures
reliable pick and place operations. Core construction and
encapsulation are rated for 125°C, which makes these
transponders ideal for higher temperature applications.
For harsh environments, please consider the 4312RV or
5315TC, which were developed for tire pressure monitoring systems.
The 4308RV transponders coils are available in 5% and
2% tolerances. In addition to the standard models shown,
Coilcraft can design coils to operate at other frequencies.
Coilcraft Designer’s Kit C383 contains four samples of all
5% inductance tolerance parts. To order, contact Coilcraft
or visit http://order.coilcraft.com.

1. When ordering, please specify tolerance and packaging codes:
4308RV-905XJLD
Tolerance: G = 2% J = 5% (Table shows stock tolerances in bold.)
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.
3. Tolerances in bold are stocked for immediate shipment.
4. Read distance measured using the KEELOQ® Transponder Evaluation
Kit part number DM303005 from Microchip. Distance was recorded as
the voltage across the resonant circuit dropped below 10 mV.
5. Sensitivity measured in accordance with Coilcraft application note
“Measuring Sensitivity of Transponder Coils.”
6. Matching capacitor value required for parallel resonant circuit operating
at 125 kHz.
7. DCR measured on micro-ohmmeter.
8. SRF measured using Agilent/HP 8753D network analyzer.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
