(1/10w), 10 f or more) such as external circuit example above near v cc . 1. when this infrared remote control detecting unit shall be adopted for wireless remote control, please use it with the signal format of transmitter, which total duty ratio d t (emitting time n t n / transmitting time for 1 block t) is 40% or less. on signal time t on (pulse width of the presence of modulated ir) should be 250(200:in case of b.p.f. center frequency:56.8khz model) s or more. in case that the signal format of total duty and on signal time is out of above conditions, there is a case that reception distanc e is much reduced or output is not appeared. 2. use the light emitting unit (remote control transmitter), in consideration of performance, characteristics, operating condit ions of light emitting device and the characteristics of the light detecting unit. 3. pay attention to a malfunction of the light detecting unit when the surface is stained with dust and refuse. care must be taken not to touch the light detector surface. if it should be dirty, wipe off such dust and refuse with soft cloth so as to prevent scratch. in case some solvents are requi red, use methyl alcohol, ethyl alcohol or isopropyl alcohol only. also, protect the light detecting unit against flux and others, since their deposition on the unit inside causes reduction of t he function, fading of markings such as the part number. 4. the shield case should be grounded on pcb pattern. (the area across the shield case and the gnd terminal is internally conductive in some cases and non-conductive in some other cases.) 5. do not apply unnecessary force to the terminal and the case. 6. do not push the light detector surface (photodiode) from outside. 7. to avoid the electrostatic breakdown of ic, handle the unit under the condition of grounding with human body, soldering iron , etc. 8. do not use hole and groove set in the case of the light detecting unit for other purposes, since they are required to mainta in the specified performance. 9. external circuit examples (mount the outer parts as near the unit as possible). precautions for operation n = 1 t 1 t 2 t 3 t n t on transmitting time for 1 block:t d t =( t n / t) 100 (%) n n = 1
gp1um26rk/27rk/28rk/28qk series 10. there is a possibility that noise on output may be caused by environmental condition (disturbing light noise, electromagnet ic noise, power supply line noise, etc.) even if there is no input transmission signal. 11. please shall confirm operation or your actual machine. because the output pulse width of this product is fluctuated by environmental conditions such as signal format, temperature, distance from transmitter, and so on. 12. in case that this product is kept in high humidity condition, it may be hard to solder, please be careful enough about stor age method. depend on the flux you select, there are different solderabilities, so please select a suitable flux and use it. 13. please use this device away from the dew drop. be aware that the dew drop rusts shield case and others, may affect the electric characteristics.
