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 encapsu-
lation are rated for 125°C, which makes these transpon-
ders ideal for higher temperature applications.
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-905X
JLD
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. Operating temperature range
40°C to +125°C.
10. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
