RFID Transponder Coils – 5315TC

Document 311 -1

Document 311-1 Revised 02/19/09

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 surfaces

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, includ-

ing 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 ana-

lyzer at 125 kHz. For recommended test procedures, contact Coilcraft.

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 “Mea-

suring 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.
