FEATURES
1. Compact choke coils selectable from 4, 5, or 6mm in height.
2. A medium or large current can be flown according to the specifications.
3. Closed magnetic circuit (with a ring core) L type and open magnetic circuit (a drum core only) D type are
selectable.
4. These choke coils can be mounted automatically by reflow soldering with taping.
5. Owing to multiple terminals (7 terminals), a transformer containing many circuits can be designed.
