  We have designed superinductors made of strongly disordered superconductors
for implementation in "hybrid" superconducting quantum circuits. The
superinductors have been fabricated as meandered nanowires made of granular
Aluminum films. Optimization of the device geometry enabled realization of
superinductors with the inductance $\sim 1 {\mu}H$ and the self-resonance
frequency over 3 GHz. These compact superinductors are attractive for a wide
range of applications, from superconducting circuits for quantum computing to
microwave elements of cryogenic parametric amplifiers and kinetic-inductance
photon detectors.
