Type 278
(No.P-278-E004)
Type 278 tantalum chip capacitors is ultra miniature tantalum chip capacitors with case size 2012 (2.0×1.25×1.2mm
thick). The capacitors are designed to meet the demands for further miniature of devices.
FEATURES
1. Suitable for surface mounting with high precise dimensional accuracy
2. Soldering:260℃ for 10 seconds by reflow or flow soldering.
3. Type 278 is suitable for miniature applications such as DVC, DSC and PCMCIA cards, and high-function compact
portable devices such as mobile phones and s
martphones.
4. Lead-free and RoHS Compliant
5. Halogen and antimony free product is available upon requect.
