SURFACE MOUNT DEVICE LED
Part No. : LT650WDT-WW2
REV: A / 0
Notes:
1. Luminous intensity is measured with a light sensor and filter combination that
proximities the CIE eye-response curve.
2.
1/2 is the off-axis angle at which the luminous intensity is half the axial luminous
θ
intensity.
3. Caution in ESD :
Static Electricity and surge damages the LED. It is recommended use a wrist band or
anti-electrostatic glove when handling the LED. All devices, equipment and machinery
must be properly grounded.
4. Major standard testing equipment by “Instrument System” Model : CAS140B Compact
Array Spectrometer and “KEITHLEY” Source Meter Model : 2400.
