  1. When ordering, please specify packaging code: 4312RV-725XGLD
  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
