Notes

When ordering, please specify packaging code: 4312RV-725XGLD
Inductance and Q measured using Agilent/HP 4192A impedance analyzer at 125 kHz. For recommended test procedures, contact Coilcraft
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.
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 on micro-ohmmeter
SRF measured using Agilent/HP 8753D network analyzer

Termination:

RoHS compliant gold over nickel over phos bronze.

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (3000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
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 D.
