Document 461-1 RFID Transponder Coils 4312RV AEC The 4312RV series of transponder coils is designed for + Q200 125C RFID applications at 125 kHz. It is Coilcrafts smallest transponder coil developed specifically for the harshest mechanical environments. The coil is wound on a plastic base, providing great du- rability and allowing this part to withstand physical shock. With operating temperature range to 125C, these parts pass AEC-200 Grade 1 (-40C to +125C) qualification and are ideal for use in a wide range of automotive ap- plications. 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: Weight 210 240 mg 4312RV-905XGLD Ambient temperature 40C to +125C Packaging: D = 13 machine-ready reel. EIA-481 embossed plastic tape (3000 parts per full reel). Quantities less than Storage temperature Component: 40C to +125C. full reel available: in tape (not machine ready) or with Tape and reel packaging: 40C to +80C leader and trailer ( 25 charge). Resistance to soldering heat Max three 40 second reflows at B = Less than full reel. In an effort to simplify our part +260C, parts cooled to room temperature between cycles numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30C / change the last letter of your part number from B to D. 85% relative humidity) 2. Inductance and Q measured using Agilent/HP 4192A impedance Temperature coefficient of inductance +300 to +1100 ppm/C analyzer at 125 kHz. For recommended test procedures, contact Packaging 3000 per 13 reel Plastic tape: 24 mm wide, Coilcraft. 0.3 mm thick, 8 mm pocket spacing, 2.49 mm pocket depth 3. Read distance measured using the KEELOQ Transponder Evaluation Kit part number DM303005 from Microchip. Distance was recorded as PCB washing Tested with pure water or alcohol only. For other solvents, the voltage across the resonant circuit dropped below 10 mV. see Doc787 PCB Washing.pdf. 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.
