📖 Inductance Conversion Guide
🎯 What is Inductance?
Inductance is the property of a conductor to oppose changes in current. It's measured in henries (H) and relates to the magnetic field created by current flow.
  • Henry (H) is the base unit
  • Higher inductance = more opposition to current change
  • Creates magnetic field when current flows
  • Stores energy in magnetic field
🔧 Unit Prefixes
Understanding metric prefixes is essential for working with inductance values in electronics.
  • nano (n) = 10⁻⁹ (0.000000001)
  • micro (μ) = 10⁻⁶ (0.000001)
  • milli (m) = 10⁻³ (0.001)
  • kilo (k) = 10³ (1,000)
⚡ Inductor Behavior
Understanding how inductors behave in circuits is fundamental to electronics design.
  • Opposes changes in current
  • Passes DC, opposes AC
  • Current buildup follows exponential curve
  • Energy storage E = ½LI²
🚀 Selection Guidelines
Choosing the right inductor requires considering multiple factors beyond just inductance value.
  • Current rating > maximum circuit current
  • Consider DC resistance (DCR)
  • Saturation current limits
  • Core material affects frequency response
🔬 Common Applications
Inductors serve many functions in electronic circuits and power systems.
  • Power supply filtering and energy storage
  • EMI filtering and noise suppression
  • RF tuning circuits and antennas
  • Motor drives and transformers
📏 Design Considerations
Proper inductor design requires understanding of core materials and winding techniques.
  • Core permeability affects inductance
  • Turns ratio squared relationship
  • Frequency-dependent behavior
  • Thermal considerations at high currents
