The MIM-0KM1AKL 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.

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 .
