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.

11. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

10. Resistance to soldering heat: Three reflows at >217°C for 90 seconds

12. Temperature coefficient of inductance: +300 to +1100 ppm/°C.

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:

(+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room

temperature between.
