Type 278 Tantalum Solid Electrolytic Capacitors are ultra miniature tantalum chip capacitors with case size 2012 (2.0
×
1.25
×
1.2 mm thick). The capacitors are designed to meet the demands for further downsizing of devices.
FEATURES
1. Suitable for surface mounting with high precise dimensional accuracy
2. Soldering : 260°C for 10 seconds by reflow
3. Type 278 is suitable for ultra miniaturized applications, such as DVC, DSC and PCMCIA cards, and high-function compact
portable devices, such as mobile phones and PHS.
4. Lead-free and RoHS Compliant
