■Operating and handling precautions
(1) This product has its life. The product life which is described in "Reliability" should be taken
ꢀꢀꢀinto account when using it.
(2) This product will be damaged by electrostatic discharge(ESD). Following precautions should be taken
ꢀꢀꢀto avoid ESD damage.
⇒ Workers, workbenches and other equipment should always be grounded. Workers should always wear
ꢀꢀꢀan antistatic wrist strap and an antistatic smock on them.
⇒ When handling this product, workers should always wear antistatic gloves or finger covers.
⇒ A stable DC power supply which is free from electrical transients should always be used when
ꢀꢀꢀoperating this product. A slow starter circuit should always be inserted between the power
ꢀꢀꢀsupply and this product in order to protect it from DC power surges.
⇒ Optical power output of this product should be set with a highly reliable and high quality
ꢀꢀꢀvariable resistance.
⇒ This product should always be connected to the driving circuit by soldering directly or through
ꢀꢀꢀhighly reliable connectors.
⇒ While this product is being operated, be sure to avoid touching the driving circuit or the
ꢀꢀꢀterminals of this product with electrical probes from a synchroscope or a voltmeter.
⇒ An antistatic package should be used when storing this product.
⇒ This product should be processed in the rooms where relative humidity is kept at 50-70%RH.
(3)This product doesn't do the design that intends use in the following, special environment.
ꢀ ꢀPlease use it after confirming the performance and reliability, etc. enough in your company
ꢀ ꢀbefore use in the following special environment.
⇒Use in place where a lot of moisture, be dewys, sea breezes, or causticity gases (Cl, H2S,
ꢀꢀꢀNH3, SO2, and NOX, etc.) exist.
⇒Use under direct sunshine, in out-of-door exposure, or in dust.
⇒Use in atmosphere such as water, oil, drug solutions, or organic solvents.
⇒Use in environment with strong static electricity or electromagnetic radiation.
⇒Use in state installed near generation of heat parts or in state to arrange combustible
ꢀꢀꢀnear this product.
(4)In this Product,generation of heat happens in the laser chip because of operating.
ꢀ ꢀThe case temperature rises by this generation of heat. Because the rise of
ꢀ ꢀthe case temperature becomes a factor to shorten the lifetime of this product,
ꢀꢀ a sufficient heat sink should be attached to this product when operating so that its case
ꢀ ꢀtemperature is to be maintained at the same level as that of the surrounding.
ꢀ
(5) Even if the drive current supply has an automatic power control (APC),
ꢀꢀꢀautomatic current control (ACC), or both, be sure to monitor the optical power output
ꢀꢀꢀwith an optical power meter while setting it. Never estimate the optical power output
ꢀꢀꢀonly from the drive current because it is likely to be decreased by temperature rise
ꢀꢀꢀof the surrounding.
(6) Although the beam emitted by this laser diodes is nearly invisible,it will be harmful
ꢀꢀꢀto the human eyes. So the following precautions should be taken.
⇒ When this product is being operated, the emitting surface of a chip should not
ꢀꢀꢀbe viewed either directly or through a lens, microscope or optical fibers.
⇒ When operating this product, wear safety glasses.
(7) When soldering this product,heat lead pins only using a soldering iron in short time.
ꢀꢀꢀAvoid heat the whole package using pre-heat or reflow soldering.
