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 frequen-
cies to 200kHz.
