Transformers
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.
