Unknown component
(OP)
Hi all,
I am trying to find out that a particular component is. You will find information about this component with a picture in the attached file.
This component is used in the tuned circuit of a TDA1576, a Fm demodulator.
Any comments will be welcome!

The chip is basically a quadrature demodulator. "In the quadrature demodulator, the modulated carrier is passed through an LC tank circuit that shifts the signal by 90° at the center frequency."
I've lost count how many mysterious components I've seen with "ZA" printed on them.
