RFID Transponder Coils – 5315TC
The 5315TC is Coilcraft’s most rugged and lowest cost
antenna coil designed for RFID applications at 125 kHz.
The wrap-around terminals have large mounting sur-
faces to ensure excellent board adhesion. The coil is
wound on a plastic base, providing great durability and
allowing this part to withstand harsh mechanical shock.
Their robust construction and 125°C rating make these
parts suitable for use in the most severe environments.
They were developed for automotive applications, in-
cluding tire pressure monitoring systems.
In addition to the standard models shown, Coilcraft can
design transponder coils to operate at other frequencies.
Coilcraft
Designer’s Kit C369
contains four samples
each of the standard parts shown. To order, contact

1. When ordering, please specify
packaging
code:
5315TC-715XGLD
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 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.
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: +300 to +1100 ppm/°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
