As the resolution of the camera integrated in cellular phone becomes higher, the flashlight for the camera is required to have better directivity and brightness. Presently, white LED is the mainstream of the light source for the flashlight because of its superior packaging efficiency. However there are increasing numbers of models that use xenon tube as the light source, which requires the step-up transformer. To meet the increasing demands for the small step-up transformer, we have developed this step-up transformer <C4-T2.5R>.

1.	Terminal structure in which winding strap terminals are separated from packaging terminals (prevention of wire breaking)
2.	Adoption of J-bent terminal structure to reduce packaging footprint (19% reduction from our previous model)
3.	Optimal ferrite core design to achieve smaller size and higher efficiency
3.	Highly coupled windings to achieve higher efficiency (3% improvement from our previous model)

External dimensions	max. 4.5 × 4.5 × 2.5 (H)  (Unit: mm)
Allowable current	1A max.
Maximum power	0.8W max.
Dielectric withstanding voltage between windings	500V for one minute (There shall be no dielectric breakdown)
