UOT MIM-3377K1 Infrared receiver module Datasheet

MIM-3xx7K1
INFRARED RECEIVER MODULE
Description
The MIM-3xx7K1 is miniaturized infrared receivers for
remote control and other applications 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.

NOTE 1. Distance between emitter & detector specifies maximum distance that output wave form satisfies
the standard under the conditions below against the standerd transmitter.
(1)Measuring place ………Indoor without extreme reflection of light.
(2)Ambient light source… Detecting surface illumination shall be 200±50Lux under ordinary
hite fluorescense lamp of no high frequency lighting.
(3)Standard transmitter … Burst wave indicated in Fig 1. of standard transmitter
shall be arranged to 50mVp-p under the measuring circuit specified in Fig 2.
NOTE 2. (electro-optical charactistics) shall be satisfied after leaving 2 hours in the normal temperature .
NOTE 3. (electro-optical charactistics) shall be satisfied and no conoid deforms
and destructions of appearance .(excepting deforms of terminals)
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 .
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 .
