IV Unit mcd 4268-H4 230 270 2θ1/2 16 deg Peak Emission Wavelength λP 660 nm Dominant Wavelength λd 638 nm Δλ 20 nm Forward Voltage VF 1.8 Reverse Current IR Capacitance C Viewing Angle Spectral Line Half-Width 30 2.4 V 100 μA pF Test Condition IF = 20mA Note 1,4 Note 2 (Fig.5) Measurement @Peak (Fig.1) Note 3 IF = 20mA VR = 4V VF = 0 , f = 1MHz Note: 1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE (Commission International De L'Eclairage) eye-response curve. 2. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity. 3. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device. 4. The Iv guarantee should be added ±15%.
