1. When ordering, please specify **packaging** code: 

## **ZXC-725XJLC** 

**Packaging: C** = 7″ machine-ready reel. EIA-481 embossed plastic tape (500 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. 

   - **D** = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2000 parts per full reel). 

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.
