Low Cost Power Inductors
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
• Hot Solder, pre-tinned leads for easy PC board mounting
• Operating frequency to 100kHz
• Competitive pricing due to high volume production
• Manufactured in ISO-9001:2000, TS-16949:2002 and
ISO-14001:2004 certified Talema facility
• Fully RoHS compliant
Electrical Specifications @ 25°C
Test frequency: Inductance measured @ 10kHz/10mV
Test voltage between windings: 500Vrms
Operating temperature: -40°C to +125°C
Climatic category: IEC68-1 40/125/56
Applications
Switching Power Supplies • EMI/RFI filtering • Output Chokes
