TR1102CAP
SMD CAP Ferrite Transponder Inductor
Features
The TR1102CAP series of surface
mountable ferrite wound inductor is an
evolution of the TR1102 series, and also
one of the very rst SMD coils designed
for transponder use. Its length and cross
sectional area are optimized to achieve the
maximum sensitivity in the coil axis. And
the use of high quality plastic material for
the cap provides an additional mechanical
protection to the coil with the thinnest
walls, combined with a high performance
in temperature.
The TR1102CAP is a solution that
combines the low cost and high-speed
assembly of the circuit component, with
the high mechanical protection provided
by the cap, and it’s excellent when the
application demands a stronger coil.
