In order to meet the user need of miniaturization and high performance of mobile communication
equipment, we have developed the fillet-less surface mounted tantalum chip capacitor which is
considered for not only miniaturization / low profile but also mounting area.
Tantalum chip capacitors are used in digital mobile communication equipment, such as mobile
phone and PHS, and mobile AV equipment, such as digital video camera, digital still camera and mini-
disk player. The tantalum chip capacitors corresponding fillet-less surface mounting will contribute to
the micro-miniaturizing and higher performance of these mobile multimedia equipment.
FEATURES
1. Original face-down terminal structure makes possible of the miniaturization of components and
also mounting area because land dimensions can be designed almost the same size as the
terminal. Also, as it can form micro fillet, checking at mounting is possible.
2. In addition to the 1608 and 2012 size, 3216L and 3528L size are added to the series. These
correspond to a wide range capacitance of 4.7-220µF.
3. Standardized the height of the product to 1.1 mm (low profile) for all 2012 size to 3528L size.
4. The most suitable for high performance miniaturized mobile equipment such as DVC, DSC,
mobile phone, and PHS.
5. Type 251’s M case (face-down terminal, 1608 size) and S case (face-down terminal, 2012 size)
are registered products with JEITA / Electronic Devices Registration Center’s registration
system of surface-mount devices.
6. Lead free products.
