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
.
DJ Series Low Cost Linear Storage Chokes
Features
Low cost design
High storage capacity (to 5000Joules) in compact size
Low losses at high pulse frequencies
Five designs cover rated output currents between 1.5A and 29A
Operating frequency to 100 kHz
Low leakage inductance
Operating temperature: -40C to +120C
Small mounting area due to vertical design
Competitive pricing due to high volume production
Manufactured in ISO-9001 approved facility
Electrical Specifications at 25C
Notes:
1. L(H): Inductance is tested at 10 kHz and 10 mV
2. The Joule rating (LI) is the ability of the inductor to store energy.

DJA Series High Capacity Linear Storage Chokes
Storage capacity LI ~ 3500 & 5000 Ws ( 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.
