4308RV Series

High Temperature RFID Transponder Coils

RoHS compliant
Our 4308RV Series High Temperature RFID transponder coils are designed for RFID applications at 125kHz. Their low profile and extended length allow longer read ranges and provide higher Q.
  • For RFID applications at 125kHz
  • Low profile and extended length allow longer read ranges and higher Q
  • Encapsulated top ensures reliable pick and place operations
  • Core and encapsulation rated for 125°C
  • For harsh environments like tire pressure monitoring systems, consider our 4312RV or 5315TC.

Notes
  1. When ordering, please specify tolerance and packaging codes: 4308RV-905XJLD. 
  2. Inductance and Q measured using Agilent/HP 4192A impedance analyzer.
  3. Tolerances in bold are stocked for immediate shipment.
  4. 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.
  5. Sensitivity measured in accordance with Coilcraft application note “Measuring Sensitivity of Transponder Coils.”
  6. Matching capacitor value required for parallel resonant circuit operating at 125 kHz.
  7. DCR measured on micro-ohmmeter. 
  8. SRF measured using Agilent/HP 8753D network analyzer

Tolerance:

  • = 2%, = 5%

Termination:

  • RoHS compliant silver-palladium-platinum-glass frit.

Packaging:
