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 en-
sures reliable pick and place operations. Core con-
struction 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-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.
