| INFRARED RECEIVER MODULE Description The MIM-0KM2ASF SERIES is miniaturized infrared receivers for remote control and other appplications requiring improved ambient light rejection. The separate PIN diode and preamplifier IC are assembled on a single leadframe. The epoxy package contains a special IR filter. This module has excellent performance even in disturbed ambient light applications and provides protection against uncontrolled output pulses. MIM-0KM2ASF Features Photo detector and preamplifier in one package Internal filter for PCM frequency High immunity against ambient light Improved shielding against electric field disturbance 2.4-Volt supply voltage; low power consumption TTL and CMOS compatibility MIM-0KM2xSF Series Models MIM-0KM2ASF 37.9KHz MIM-0KM2BSF 32.7KHz MIM-0KM2CSF 40.0KHz MIM-0KM2DSF 36.7KHz MIM-0KM2FSF 56.7KHz UNIT : mm BLOCK DIAGRAM VS TRAP BPF TRIMMING Output ABLC fo GND Unity Opto Technology Co., Ltd. 02/06/2001 MIM-0KM2ASF Absolute Maximum Ratings Item Supply voltage Operating temperature Storage temperature Soldering temperature Symbol VCC Topr Tstg Tsd Ratings 5.8 -10 ~ + 60 -20 ~ + 75 260 Unit V Maximum 5 seconds @ Ta=25 Remark Electro-optical characteristics (Vcc=2.4V) Parameter Current consumption Response wavelength Tuning frequency Output form H level output voltage L level output voltage H level output pulse width L level output pulse width Distance between emitter & detector Half angle V0h V0l Twh Twl L 400 400 10.0 45 Symbol Icc p f0 940 37.9 , 32.7 , 40.0 , 36.7 , 56.7 Min.

Inspection standard 1.Among electrical characteristics , total number shall be inspected on items blow. 1-1 front distance between emitter & detector 1-2 Current consumption 1-3 H level output voltage 1-4 L level output voltage 2.Items except above mentioned are not inspected particularly , but shall fully satisfy CAUTION ( When use and storage of this device ) 1.Store and use where there is no force causing transformation or change in quality . 2.Store and use where there is no corrosive gas or sea(salt) breeze . 3.Store and use where there is no extreme humidity . 4.Solder the lead-pin within the condition of ratings. After soldering do not add extra force . 5.Do not wash this device . Wipe the stains of diode side with a soft cloth. You can use the solvent , ethylalcohol or methylalcohol or isupropylene only . 6.To prevent static electricity damage to the Pre-AMP make sure that the human body , the soldering iron is connected to ground before using . 7.Put decoupling device between Vcc and GND for reduse the noise from power supply line . 8.The performance of remote-control system depends on environments condition and ability of periferal parts. Customer should evaluate the performance as total system in those conditions after system up with components such as commander , micon and this receiver module . Guarantee period and scope 1.Guarantee period One year after delivery to desired place . 2.Guarantee scope A re-delivery of goods will be carried out if the cause of malfunction lies in our device .However no responsibilities be taken for the inconveniences caused by the malfunction of our devices . Others 1.This device is not design to endure radiative rays and heavily charged particles . 2.In case where any trouble or questions arise,both parties agress to make full discussion covering the said problem .
