About Attohenries
The attohenry (aH) equals 10⁻¹⁸ H, the scale for parasitic inductances in on-chip metal interconnects and quantum-device bondwires. Metal traces in sub-10 nm CMOS processes have via-to-via inductances in the attohenry range; superconducting qubit junctions are modelled with loop inductances of tens to hundreds of attohenries; microwave integrated circuit (MMIC) vias at 100 GHz are characterised in aH. 1 aH = 10⁻³ fH = 10⁻¹⁸ H.
About Millihenries
The millihenry (mH) equals 10⁻³ H, the scale for audio-frequency transformers, relay coils, and resonant filter inductors. Telephone voice-frequency transformers use 10-200 mH; relays and solenoids have coil inductances of 1-100 mH; tunable AM IF transformers operate at 200-500 mH; loudspeaker crossover inductors (2-8 kHz) are typically 0.5-5 mH. 1 mH = 10⁻³ H = 10³ µH.
