Document 461-1 RFID Transponder Coils – 4312RV The 4312RV series of transponder coils is designed for RFID applications at 125 kHz. It is Coilcraft’s smallest transponder coil developed specifically for the harshest mechanical environments. The coil is wound on a plastic base, providing great durability and allowing this part to withstand physical shock. With operating temperature range to 125°C, these parts pass AEC-200 Grade 1 (-40°C to +125°C) qualification and are ideal for use in a wide range of automotive applications. The uniquely shaped termination provides excellent board adhesion. In addition to our standard models, Coilcraft can also design transponder coils to operate at other frequencies.

When ordering, please specify packaging code: 4312RV-725XGLD Packaging:D=13″ machine-ready reel. EIA-481 embossed plastic tape (3000 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. 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.
