Morphology

tank + circuit

Although the constituents 'tank' (a vessel) and 'circuit' (an electrical route) are individually transparent, their combination names a specific technical device (an LC resonant circuit) whose function (energy oscillation between components) is not inferable from the literal meanings. The use of 'tank' here is a specialized/historical metaphor in electronics, so a B1 learner who knows the words but lacks technical exposure would not be able to derive the MWE meaning.

Etymology

The noun tank circuit comes from the picture of a tank that holds something. The electronic circuit stores and moves energy back and forth between parts, so it acts like a small energy 'tank' and makes a steady signal at a particular frequency.
