TR1102 TR1102 SMD Ferrite Transponder Inductor ((2.38mH - 9mH) 

TR1102 SMD Ferrite Transponder Inductor ((2.38mH - 9mH)

The TR1102 series of surface mountable ferrite wound inductor is the very first SMD coil designed for transponder use. Its length and cross sectional area are optimized to achieve the maximum sensibility in the coil axis. Its size is excellent for plastic moulded inmobilizer transponders. 

The TR1102 is the best solution when both cost and high-speed assembly of the circuit components are sought.

  • Size: 11 x 2.6 x 2.2 mm.
  • Terminals: Ag-Ni-Sn100.
  • Wire: H, 180ºC, Solderable.
  • Max. Operating Temperature +125ºC.


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

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.
