[Data Sheet]
Visual light emitting diode does not contain reinforcement materials such as glass fillers.
Therefore if sudden thermal and mechanical shock are given, destruction or inferiority of luminous
intensity may occur. Please take care of the handling.
Please consult with us if any problems in the evaluation stage.
■ATTENTION POINTS IN HANDLING
  to avoid the remained stress and solder heat stress.
  
Enough evaluation is requested before deciding assembly and soldering conditions.
  failure during soldering or using. Please design the through-holes of PCB suitable for lead pins
  space or lead pins space after forming to avoid the physical stress on resin.
 (1) In case of soldering on PCB, If the operation is done with stress, it may cause non-lighting
[SLR-343x/SLR343x series]
  In case of direct mount on PCB(SLR/SLI-343 series), please take care about clinch of LED pins
■FIXATION METHOD
1.ATTENTION POINTS
 (1) Please do not give excessive heat over storage temperature to resin.
  In case that the product has to be heated in oven for the glue fixing of surface mount parts,
  this LED should be mounted after the glue fixing.
 (2) Please avoid stress to resin at high temperature.
2. TERMINATION PROCESSING
 (1) In case of termination processing, please fix the
  termination
 (2) Processing position, and process the reverse side
  of LED body.
  If stress is given during processing, It may cause
  non-lighting failure.
 (3) Please process before soldering.
3. ASSEMBLY ON PC BOARD

[Data Sheet]
   The Product is LED. We are not responsible for the usage as the diode such as Protection Chip,
Rectifier, Switching and so on.
   The product is part of semiconductor and electrostatic sensitive, thereʼs high possibility to be
   damaged by the electrostatic discharge.
   Please take appropriate measures to avoid the static electricity from human body and earthing
  setting of production equipment. The resistance values of electrostatic discharge (actual values)
  are different varies with products, therefore, please call our Sales staffs for inquiries.
Applications with strong electromagnetic wave such as, IH cooker, will influence the reliability of LED,
therefore please evaluate before using it.
    (ammonia), it may result in low soldering ability (caused by the change in quality of the plating
   die bonding (Ag-paste) materials. All of the above will cause function failure of the products.
   Therefore, please pay attention to the storage environment for mounted product (concern the
   generated gas of the surrounding parts of the products and the atmospheric environment).
2. Electrostatic Damage
3. Electromagnetic Wave
[SLR-343x/SLR343x series]
■APPLICATION METHOD
1.Precaution for Drive System and Off Mode
   ・Design the circuit without the electric load exceeding the ABSOLUTE MAXIMUM RATING that
   applies on the products.
   ・If drive by constant voltage, it may cause current deviation of the LED and result in deviation of
   luminous intensity, so we recommend to drive by constant current. (Deviation of VF Value will
   cause deviation of current in LED.)
・Furthermore, for off mode, please do not apply voltage neither forward nor reverse. Especially,
for the products with the Ag-paste used in the die bonding, thereʼs high possibility to cause electro
migration and result in function failure.
2. Operation Life Span
   Thereʼs possibility for intensity of light drop according to working conditions and environments
    (applied current, surrounding temperature and humidity, corrosive gases ), please call our Sales
   (1) Longtime intensity of light life
3. Usage
   staffs for inquiries about the concerned application below.
   (2) On mode all the time
■OTHERS
