Features:
1. Package in 8.0mm carrier tape on 7" diameter reel.
2. Compatible with automatic placement equipment.
3. Compatible with reflow solder process.
Descriptions:
1. The LG-170 SMD Taping 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.
2. Besides, lightweight makes them ideal for miniature
applications. etc.
Applications:
1. Automotive : backlighting in dashboard and switch.
2. Telecommunication : indicator and backlighting in telephone and fax.
3. Flat backlight for LCD, switch and symbol
4. General use.
