frequency (f) and duty factor (df) will be used. 2. determine the maximum tolerable peak current ratio from figure 2. 3. determine the maximum forward current from figure 3. for example, when ta = 40 c or above, the maximum forward current (i f max.) decreases. 4. calculate the maximum tolerable peak current (i f peak max.). example if f = 1 khz, df = 10%, and ta = 40 c, the maximum toler- able peak current ratio from figure 2 is 3.0 for red, orange and yellow, and 2.4 for green. the maximum forward current i f max. at ta = 40 c is 20 ma for red, orange and yellow, and 25 ma for green. therefore, the maximum tolerable peak current under these conditions is as follows : red, orange and yellow 20 ma 3.0 = 60 ma . . green 25 ma 2.4 = 60 ma . . . . . . . . . . . . . . . . . . for the repetition frequency, we recommend 1 khz or above. (7) decrease of rated current the maximum rated forward current of led lamps will vary depending on the ambient operating temperature. (refer to figure 3) (8) variation of luminous intensity depending on ambi- ent temperature rohm led lights have a temperature coefficient of approximately 1% for red and orange, and 0.5% for yellow and green. (refer to the luminous intensity vs. case temperature characteristics for each led type.) storage precautions storage in a dry box is best. however, if this is not pos- sible we recommend the following conditions : temperature : 5 to 30 c humidity : 60%rh max. recommended pcb we recommend the following hole diameters. note, how- ever, that these may vary depending on the board materi- al, degree of integration, and wiring. led lamp product names the product names of rohm led lamps and chip leds are coded as follows : |
