X/Y axis Micro SMD Hard Ferrite RFID Transponder Coil

The TP0602 Series of Surface Mountable ferrite wound inductor is a small transponder inductor solution for automotive applications like TPMS,Keyless Go and Keyless entry systems:


  • Size: 6.6mm x 2.3mm x 1.75mm.
  • Good mechanical perfomace.
  • High sensitivity for 20KHz, 40KHz and 125KHz applications.
  • Good perfomance in thermal shock test.
  • Good cost/perfomance ratio.
  • Available high inductance version for hearing aids applications.
  • This component is also functional to 20kHz and 134kHz. 



Good solution for TPMS moulded solutions. The TP0602 is the smaller SMD transponder coil available in the market.

  • Terminals: Ag-Ni-Sn100.
  • Wire: H, 180ºC, Solderable.
  • Max. Operating Temperature 130ºC.


The specification chart is a reference guide for the most common required values at working frequencies of 125 kHz and 20 kHz. Any other inductance value at LF or tighter tolerances can be provided. Please contact our sales deparment for any inquiry.

 This product has a datasheet available upon request.

TP0602 Pad layout


Recommended reflow profile. 

Reflow soldering, vapour-phase soldering. A maximum soldering temperature of 260ºC during 10 s should not be exceed for (see recommended soldering profile with maximum and minimum temperature-time).



The reflow condition recommended is according to the machine used by our company. Big differences will arise as a result of the type of machine, reflow conditions, method, etc used.
