Its definitely an inductor - quite likely a linearity coil (polarising
stripe is an obvious clue) close examination may reveal that the ferrite
bobbin has an extra bit glued on the end opposite the leadout wires, this
will be magnetic which is easily confirmed by offering it the tip of a
screwdriver.

Could you elaborate on this type of inductors?
Polarized? what does the magnet do?

Makes it easier to saturate the core with current in one direction than the
other.
