SDF-0.63-400 Datasheet, PDF (1/3 Pages) Nuvotem Talema – SD Series High Efficiency Storage Chokes
SD Series • High Efficiency Storage Chokes
SD Series storage chokes provide excellent efficiency and field modulation
when used as loading coils for interim energy storage with switch mode
power supplies. The use of MPP cores allows compact size, a highly stable
inductance over a wide bias current range and high "Q" with operating
frequencies to 200kHz.
Features
• Operating frequency to 200kHz
• Small size and high "Q"
• Highly stable inductance with changing bias current
• Fully encapsulated styles available meeting class GFK
(-40°C to +125°C, humidity class F) per DIN 40040.
• Manufactured in ISO-9000 approved factory
Electrical Specifications at 25°C
