MITSUMI Transformers for Inverter or Converter C8-R Series Coils, Filters OUTLINE Choke coil for various kinds of electronic equipment such as DC-DC converter, switching power supply, power supply circuits for TV and VCR and such., and other various kinds of electronic equipment. C8-R Series C8-R4D C8-R4L C8-R5D C8-R5L C8-R6D C8-R6L 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.
