About Femtohenries

The femtohenry (fH) equals 10⁻¹⁵ H, the scale for PCB via inductances, short bondwires, and on-chip spiral inductor parasitics in millimetre-wave design. A 0.5 mm gold bondwire has about 0.5-1 fH inductance at mm-wave frequencies; differential pair stubs in 100 GHz SerDes are modelled in femtohenries; Josephson junction loop inductances in superconducting circuits are a few hundred fH. 1 fH = 10⁻³ pH = 10⁻¹⁵ H.

About Microhenries

The microhenry (µH) equals 10⁻⁶ H, the standard unit for power-electronics inductors, EMI filter chokes, and AM radio coils. DC-DC converter inductors in smartphones are 1-100 µH; ferrite-core EMI common-mode chokes are 10-10 000 µH; AM broadcast loop antennas are 200-500 µH; automotive ignition coil secondary inductances are a few µH. 1 µH = 10⁻³ mH = 10⁻⁶ H.
