2)Supply current : 0 ~ 3.0㎃
3)Output current : 0 ~ 2.5㎃
4)Operating temperature : -20℃ ~ +80℃
5)Storage temperature : -30℃ ~ +85℃
6)Reflow soldering temperature (Pb Free) : 260℃(Max 5 sec)
5. Cautions
1)Store and use where there is no force causing transformation or change in quality.
2)Store and use where there is no extreme humidity.
3)In order to prevent damage from static electricity, make sure that the human body and the soldering iron are connected to ground before using.
4)The ripple noise from power supply lines may shorten detecting distance of IR receiver module. Thus, in order to ensure more reliable operating please add RC filter(R=100Ω, C=47㎌) between Vcc and GND.
5)When a disturbance signal is applied to the series, it can still receive the data signal. However the sensitivity is reduced to the level that no unexpected pulses will occur. Some examples of such disturbance signals which can be suppressed pulses by the series.
ⓐDC light(Ex. From tungsten lamp or sunlight)
ⓑContinuous signal at center frequency or any other frequency
ⓒSignals from fluorescent lamps with electronic ballast with high or low mosulation.
