DP - Compact Power Chokes, Low price - DPO, DPC, DPB, DPV, DPF.

Return to normal view DP Series Power inductors provide an excellent, low cost alternative to conventional chokes or inductors. Used in EMI filtering and energy storage, these compact, low radiation inductors are extremely effective in controlling AC output ripple of Switch Mode Power Supplies.

Features

  • Broad range of inductance values and current ratings
  • Low cost, no radiation design
  • Compact size, for high density packaging 
  • Hot solder, pre-tinned leads for easy PC board mounting
  • Operating frequency to 100 kHz
  • Competitive pricing due to high volume production
  • Manufactured in ISO-9000 approved facility
   DP - Compact Power Chokes, Low price

Applications

  • Switching Power Supplies
  • EMI/RFI filtering
  • Output Chokes

Notes:

  1. The µJoule rating (0.5 x LI2) is the ability of the inductor to store energy
  2. Inductance is measure at 0.10Vrms @ 10kHz without DC Current and 0.25Vrms @ 10kHz with DC Current.
