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 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.

6. DCR measured on micro-ohmmeter.
7. SRF measured using Agilent/HP 8753D network analyzer.
8. Ambient temperature range: 40°C to +125°C
9. Storage temperature range: Component: 40°C to +125°C
Packaging: 40°C to +80°C
10. Resistance to soldering heat: Three reflows at >217°C for 90 seconds
(+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room
temperature between.
1. 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.
11. Electrical specifications at 25°C.
12. Temperature coefficient of inductance: +300 to +1100 ppm/°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
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.
