RGB LED spec
SPNovaLEDTMFeaturing a staggering brilliance and significant flux output, the SPNovaLED™ showcases the latest technological advent in this range. With its extremely high level of brightness and the ultra low high profile, which is only 1.5 mm are highly suitable for both conventional lighting and specialized application such as automotive signal lights, traffic lights, channel lights, tube lights and garden lights among others.
Features:
> Super high brightness surface mount LED.
> High flux output.
> 125° viewing angle.
> Compact package outline (LxWxH) of 6.0 x 6.0 x 1.5mm.
> Ultra low height profile - 1.5 mm.
> Designed for high current drive; typically 250 mA.
> Low junction-to-solder point thermal resistance; RTH js = 50 K/W.
> Qualified according to JEDEC moisture sensitivity Level 2.
> Compatible to IR reflow soldering.
> Environmental friendly; RoHS compliance.
Applications:
> Signage: full colour display video notice board, signage, special effect lighting.
> Lighting: architecture lighting, general lighting, garden light, channel light.
