Document 450-1 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. To request free evaluation samples, contact Coilcraft or visit www.coilcraft.com.

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.” Sensitivity4 (mV/µT) 11.76 19.80 32.80 54.76 76.97 Matching capacitor5 (pF) 4050 1621 681 331 225 SRF typ7 (kHz) 5890 3670 2200 1551 1400 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.
