Nichia offers 2 new automotive LEDs. Or rather 2 variants of the same LED with different pad layouts.
NCSW131D-PCA
NCSW170D-PCA
Highlights:
- 15% smaller die than White Flat (Osram KW CSLNM1.TG)
- higher Vf
- about the same lm/A but a little lower lm/W
- lower thermal resistance(!), 3.9 K/W for Nichia 4.1 for Osram
- small thermal pad
- small, asymmetric package
Unlikely to challenge Boost HX when it comes to ultimate throw but may compete with White Flat in the small thrower space.
