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-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).
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. Ambient temperature range:
10. Storage temperature range: Component:
Packaging:
–
40°C to +125°C
40°C to +125°C
40°C to +80°C
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.

11. Resistance to soldering heat: Three reflows at >217°C for 90 seconds
(+260°C 5°C for 20 – 40 seconds), allowing parts to cool to room
temperature between.
12. Electrical specifications at 25°C.
13. Temperature coefficient of inductance: +200 to +700 ppm/°C

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.
Specifications subject to change without notice.
