RFID Transponder Coil – 4513TC
The 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.
The coil is wound on a plastic base, providing great
durability and allowing this part to withstand harsh
mechanical shock. With operating temperature range
to 125°C, these coils are ideal for a wide range of
applications.
In addition to our standard models, Coilcraft can design
transponder 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).
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 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.

Ambient temperature range:
–40°C to +125°C
9.
Storage temperature range:
Component: –40°C to +125°C
Packaging: –40°C to +80°C
10.
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.
11. Electrical specifications at 25°C.
12. Temperature coefficient of inductance: +50 to +210 ppm/°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
