About Nanohenries
The nanohenry (nH) equals 10⁻⁹ H, the everyday unit for RF inductors, PCB trace inductance, and package parasitics. A 10 mm PCB microstrip trace is about 10 nH; surface-mount RF chokes range from 1 to 1 000 nH; bond-wire lead inductances are 1-20 nH; resonant LC tank circuits for Bluetooth and Wi-Fi use inductors of 1-100 nH. 1 nH = 10⁻³ µH = 10⁻⁹ H.
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.
