Specifications are subject to change without notice.
Handling Cautions for Optoelectronic Devices
(1-1) The products described in this specification are designed and manufactured for use in general communication
systems or electronic devices, unless their applications or reliability are otherwise specified. Therefore, they are not
designed or manufactured for installation in devices or systems that may affect human life or that are used in social
infrastructure requiring high reliability.
(1-2) When the customer is considering to use the products described in this specification in special applications, such
as transportation systems (automobiles, trains, vessels), medical equipments, aerospace, nuclear power control, and
submarine repeaters or systems, please contact Mitsubishi Electric or an authorized distributor.
2. Storage Conditions
When storing the products, it is recommended to store them following the conditions described below without opening
the packing. Not taking enough care in storing may result in defects in electrical characteristics, soldering quality, visual
appearance, and so on. The main points are described below (if special storage conditions are given to the product in
the specification sheet, they have priority over the following general cautions):
(2-1) Appropriate temperature and humidity conditions, i.e., temperature range between 5～35 C, and humidity
between 45～75 percent RH, should be maintained in storage locations. Controlling the temperature and humidity
within this range is particularly important in case of long-term storage for six months or more.
(2-2) The atmosphere should be particularly free from toxic gases and dust.
(2-3) Do not apply any load on the product.
(2-4) Do not cut or bend the leads of the devices which are to be stored. This is to prevent corrosion in the cut or bent
part of the lead causing soldering problems in the customer’s assembling process.
(2-5) Sudden change in temperature may cause condensation in the product or packing, therefore, such locations
should be avoided for storing. Temperature in storage locations should be stable.
(2-6) Storage conditions for cap-less products shall be stated separately because these products require stricter
controls than package sealed products.
3. Design Conditions and Environment under Use
(3-1) Operation in excess of the absolute maximum ratings can cause permanent damage to the device. The customers
are requested to design not to exceed those ratings even for a short time.
(3-2) Avoid use in locations where water or organic solvents adhere directly to the product, or where there is any
possibility of the generation of corrosive gas, explosive gas, dust, salinity, or other troublesome conditions. Such
environments will not only significantly lower the reliability, but also may lead to serious accidents.
(3-3) Contamination to cap window or LD emitting point by volatile material, such as adhesive, may degrade reliability.
When a customer use adhesive material, we recommend the customer to confirm possible effect before usage.
(3-4) Quality assurance for cap-less products shall be stated separately because these products require more notice in
your line and your products environment than package sealed products.
4. Static Electric Safety Cautions
The optoelectronic devices are sensitive to static electricity (ESD, electro-static discharge). The product can be broken
by ESD. When handling this product, please observe the following countermeasures:
<Countermeasures against Static Electricity and Surge>
To prevent break of devices by static electricity or surge, please adopt the following countermeasures in the assembly
line:
(4-1) Ground all equipments, machinery jigs, and tools in the process line with earth wires installed in them. Take
particular care with hot plates, solder irons and other items for which the commercial power supplies are prone to
leakage.
(4-2) Workers should always use earth bands. Use of antistatic clothing, electric conductive shoes, and other safety
equipment while at work is highly recommended.
(4-3) Use conductive materials for this product’s container, etc.
(4-4) It is recommended that grounding mats be placed on the surfaces of assembly line workbench and the
surrounding floor in work area, etc.
(4-5) When mounting this product in parts or materials which can be electrically charged (printed wiring boards, plastic
products, etc.), pay close attention to the static electricity in those parts. ESD may damage the product.
(4-6) Humidity in working environment should be controlled to be 40 percent RH or higher.
These countermeasures are most general, and there is a need to carefully confirm the line using this product. It is
extremely important to prevent surge, eliminate it rapidly, and prevent it from spreading.
