TR1102
SMD Ferrite Transponder Inductor 11x2.6x2.2 mm (0.29 mH - 16.2 mH)
Features
The TR1102 series of surface mountable ferrite
wound inductor is the very rst 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.
This component is also functional to 20kHz and
134kHz.
