DJ Series • Low Cost Linear Storage Chokes
DJ Series
Storage Chokes offer high storage capacity in a
compact, low cost design. Used primarily in switched-
mode power supplies where low losses are essential at
high pulse frequencies.
Features
• High storage capacity (to 5000µJoules) in compact size
• Low losses at high pulse frequencies
• Operating frequency to 100 kHz
• Low leakage
• Small mounting area due to vertical design
• Competitive pricing due to high volume production
• Manufactured in an ISO-9001:2000, TS-16949:2002
and ISO-14001:2004 certified Talema facility
• Fully RoHS compliant
Electrical Specifications at 25°C
Test frequency: Inductance measured @ 10kHz
and 10mV
Test voltage between windings: 500Vrms
Operating temperature: -40°C to +125°C
Climatic category: IEC68-1 40/125/56

Notes:
The µJoule rating (½LI)² is the ability of the inductor to store energy.
THE TALEMA GROUP • Magnetic Components for Universal Applications
DJA Series • High Capacity Linear Storage Chokes
Storage capacity ½ LI ² ~ 3500 & 5000 µWs (µ Joule)
~
The DJA Series utilizes Fe-based amorphous alloy cores which provide high flux density and low core loss. These storage chokes allow
you to optimize your designs by giving a highly stable inductance over a wide DC bias current range at operating frequencies to 500 kHz.
