Description

  • 3.8mm x 3.8mm shielded drum cores available in two heights: 1.2mm and 1.4mm
  • Current range from 4.44 to 0.100 Amps
  • Inductance range from 0.47 uH to 680 uH
  • Ferrite shielded, low EMI
  • Ferrite core material

Applications

  • Digital cameras, cellular phones, CD players, and PDAs
  • PCMCIA cards
  • GPS systems Environmental Data
  • Storage temperature range: -40°C to +125°C
  • Operating ambient temperature range: -40°C to +85°C (range is application specific). Temperature rise is approximately 40°C at rated rms current
  • Solder reflow temperature: +260°C max for 10 seconds max. Packaging
  • Supplied in tape and reel packaging, 4,150 parts per 13" reel SD38 Series Low Profile, Shielded Inductors (1) Test Parameters: 100KHz, 0.100Vrms, 0.0Adc. (2) RMS current for an approximate ∆T of 40°C without core loss. It is recommended that the temperature of the part not exceed 125°C. De-rating is necessary for AC currents. (3) Peak current for approximately 30% rolloff at 20°C. (4) DCR limits @ 20°C. (5) Applied Volt-Time product (V-uS) across the inductor at 100kHz necessary to generate a core loss equal to 10% of the total losses for 40°C temperature rise. De-rating of the Irms is required to prevent excessive temperature rise.
