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
(-40C to +125C, humidity class F) per DIN 40040.
Manufactured in ISO-9000 approved factory
Electrical Specifications at 25C

THE TALEMA GROUP World Wide Toroidal Specialists
The Talema engineering staff can asist in the design of other inductance values and sizes including pre-designed cable lug models to 63 Amps.
1) The Joule rating (LI) is the ability of the inductor to store energy.
2) Schematic:
1 = one winding
2P = two windings, Parallel Connection
2R = two windings, Series Connection.
3) Inductance measured at 0.10 Vrms @ 10kHz without DC Current and 0.25 Vrms @ 10kHz with DC Current.
4) On larger units and units wound with fine wire, additional mechanical mounting is recommended. See next page for Mounting Styles.
