DJ - Liniar 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

Low cost design
High storage capacity (to 5000 µJoules) in compact size
Low losses at high pulse frequencies
Five designs cover rated output currents between 1.5 A and 29 A
Operating frequency to 100 kHz
Low leakage
Operating temperature: -40°C to +120°C
Small mounting area due to vertical design
Competitive pricing due to high volume production
Manufactured in ISO-9001 approved facility

Notes:

L(µH): Inductance is tested at 10 kHz and 10 mV
The µJoule rating (1/2LI)² is the ability of the inductor to store energy.
