RFID Transponder Coil – 4513TC
AECThe 4513TC is Coilcraft’s best performing transponder
coil designed for RFID applications at 125 kHz. It offers
better sensitivity, greater read distance and higher SRF
than other coils its size.

Q200 +125°C

The coil is wound on a plastic base, providing great durability and allowing this part to withstand harsh mechanicalshock. With operating temperature range to 125°C, thesecoils are ideal for a wide range of applications.
In addition to our standard models, Coilcraft can designtransponder coils to operate at other frequencies.

1. When ordering, please specify packaging code:
4513TC-725XGLD
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic
tape (2500 parts per full reel). Quantities less thanfull reel available: in tape (not machine ready) or withleader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to D.
2. Inductance and Q measured using Agilent/HP 4192A impedance
analyzer at 125 kHz. For recommended test procedures, contact
Coilcraft.
3. 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.
4. Sensitivity measured in accordance with Coilcraft application note
“Measuring Sensitivity of Transponder Coils.”
5. Matching capacitor value required for parallel resonant circuit operating
at 125 kHz.
6. DCR measured on micro-ohmmeter.
7. SRF measured using Agilent/HP 8753D network analyzer.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
