Document 597-1 Z-Axis RFID Transponder Coils – ZXC • Z-axis RFID coil can be used with any of our other RFID coils for a complete three-dimensional solution. • Only 10 mm square and 2 mm tall • Four mounting pads for exceptional board adhesion Core material Ferrite Terminations RoHS matte tin over nickel over phos bronze. Other terminations available at additional cost. Weight 53 – 56 g Ambient temperature –40°C to +125°C Storage temperature Component: –40°C to +125°C. Packaging: –40°C to +80°C Resistance to soldering heat Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles Temperature Coefficient of Inductance (TCL) +25 to +200 ppm/°C Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C / 85% relative humidity) Mean Time Between Failures (MTBF) 26,315,789 hours Packaging 500/7″reel; 2000/13″ reel Plastic tape: 24 mm wide, 0.3 mm thick, 12 mm pocket spacing, 2.24 mm pocket depth PCB washing Only pure water or alcohol recommended Part number1 ZXC-255XJL_ ZXC-495XJL_ ZXC-715XJL_ ZXC-116XJL_ ZXC-156XJL_ Inductance2 at 125 kHz ±5% (mH) 2.48 4.90 7.10 11.4 14.8 Q min2 57 64 65 60 55 Read distance3 (inches/cm) 33 / 83.8 33 / 83.8 31 / 78.7 31 / 78.7 31 / 78.7 Sensitivity4 (mV/µT) 9.75 18.0 25.0 50.0 77.0 Matching capacitor5 (pF) 654 331 228 142 110 DCR max6 (Ohms) 37 43 62 110 160 SRF typ7 (kHz) 1975 1370 1220 990 815 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. Specifications subject to change without notice.
