INDUCTIVE COMPONENTS_SMD INDUCTOR

What Is An Inductor

• Passive components that stores energy as magnetic field
  Allow DC Current to Pass
  Block AC current or change in current
  Can be called “Chokes”, “Reactors”, “Coils”
• Application
  Part of DC DC converter (voltage regulation for circuit operation)
  Coupled with capacitor for filter (noise suppression of surge currents)

Typical CIP Grades

• soft grades
  CIP SQ
  – standard grade, with silica dots – no coating, requires insulation
  CIP SQ-I
  – CIP SQ with phosphate insulation for improved core loss
  CIP SW-S
  – special coating gives high resistance (10⁹Ω) and improved corrosion resistance
  CIP SP-I
  – insulated grade with higher permeability and higher core loss (bigger particles)

• hard grades
  CIP EW
  – standard grade with best core loss around 20 MHz
  H – grades
  – special grades with best core loss around 30 MHz
