About Henries
The henry (H) is the SI derived unit of electrical inductance, equal to 1 volt-second per ampere (1 V·s/A = 1 Ω·s = 1 kg·m²·A⁻²·s⁻²), named after Joseph Henry (1797-1878). Mains-frequency (50/60 Hz) power transformers have primary inductances of 1-100 H; loudspeaker crossover woofer inductors are 1-5 mH; large power-line reactors are 0.1-10 H. 1 H = 10³ mH = 10⁶ µH.
About Picohenries
The picohenry (pH) equals 10⁻¹² H, the practical unit for short PCB traces, decoupling capacitor equivalent series inductance (ESL), and bond-wire inductance in RF packages. A 1 mm PCB trace (50 Ω microstrip) has about 1 nH/mm; SMD bypass capacitors have ESL of 0.1-2 nH; gold bondwires are 1-5 pH/mm. IC package lead inductances are typically 1-10 nH = 1 000-10 000 pH. 1 pH = 10⁻³ nH = 10⁻¹² H.
