Transformers LDT Series LDT5656 Type
For Power Supply
SMD
These are ultra-low-profile compact multi-output power supply
transformers that increase the flexibility in designing compact and
thin digital devices, including digital cameras.
FEATURES
• With a height of only 2 mm (or 3 mm), these products are
optimally suited as power supply transformers for small and thin
devices.
• They are lightweight with a mass of 0.2g (0.25g).
• Because the coiled terminals and terminals that are attached to
the board are separated from each other, these transformers
can be mounted and soldered to boards with a high degree of
reliability.
• These products support lead-free soldering.
APPLICATIONS
DC to DC converter transformers in small and thin electronic
devices, CCD power supplies, LCD power supplies, digital still
cameras, digital movie cameras and pocket game machines, etc.
