EVERLIGHT 25-21 DATA SHEET
EVERLIGHT ELECTRONICS CO.,LTD.
Technical Data Sheet
Reverse Package Chip LED with Inner Lens
Features
․Package in 8mm tape on 7〞diameter reel.
․Compatible with automatic placement equipment.
․Compatible with infrared and vapor phase reflow
solder process.
․Mono-color type.
․Pb-free.
․The product itself will remain within RoHS compliant version.
Descriptions
․The 25-21 SMD LED is much smaller than lead
frame type components, thus enable smaller
board size, higher packing density, reduced
storage space and finally smaller equipment to be
obtained.
․Besides, lightweight makes them ideal for
miniature applications. etc.
Applications
․Backlighting in dashboard and switch.
․Telecommunication: indicator and backlighting in
telephone and fax.
․Flat backlight for LCD, switch and symbol.
․General use.
