Notes

When ordering, please specify termination and packaging codes: e.g. ZXC-156XJLD
Inductance and Q measured using Agilent/HP 4192A impedance analyzer at 125 kHz. For recommended procedures, contact Coilcraft.
Read distance measured using the KEELOQÂ® Transponder Evaluation Kit part number DM303005 from Microchip. Distance was recorded as the voltage across the resonant circuit dropped below 10mV.
Sensitivity measured in accordance with Coilcraft application note Measuring Sensitivity of Transponder Coils.
Matching capacitor value required for parallel resonant circuit operating at 125 kHz.
DCR measured at 25°C on a micro-ohmmeter. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using Agilent/HP 8753D network analyzer. Details

Refer to Application Notes Transponder Coils in an RFID System and Measuring Sensitivity of Transponder Coils for additional information.

Termination:

L = RoHS compliant matte tin over nickel over phos bronze
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (500 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (2000 parts per full reel).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
