Ultra Low Profile Surface-Mount Toroidal Power "Chip" Inductors available up to 220 µH



Standex Electronics patented ST and SP series toroidal "chip" inductors are ultra low profile, surface-mount toroidal inductors encapsulated in high temperature plastic to provide a "pick and place" compatible, surface-mount package.

Use the ST Series for:

  • High efficiency battery operated regulators
  • Discontinuous mode converters up to 1.5MHz
  • Storage inductor applications
  • Operating temperature up to 85ºc

ST series in the .pdf format

Use the SP Series for:

  • Input filters
  • Continuous mode converters up to 500KHz
  • Operating temperature up to 155ºc
  • When the very lowest stray field is required

SP series in the .pdf format

Features:

  • Ideal for DC-DC power converters in portable electronics

  • Patented insert molded packaging is smaller in O.D. and height than other components with similar electrical characteristics

  • Toroidal core - lowest stray field for close component placement

  • Very low DC resistance for very high circuit efficiency

  • Saturation current is as much as 50% higher than similar components
