5 Cautions, Life Support Policy, RoHS Declaration, and
Regulatory Information
5.1 Cautions
Failure to follow the guidelines set forth in this document may result in degrading of the
product's functions and damage to the product.
5.1.1
Design Notes
1. Follow the conditions written in this specification, especially the control signals of this
module.
2. The supply voltage must be free of AC ripple voltage (for example from a battery or a low
noise regulator output). For noisy supply voltages, provide a decoupling circuit (for
example a ferrite in series connection and a bypass capacitor to ground of at least 47 uF
directly at the module).
3. This product should not be mechanically stressed when installed.
4. Keep this product away from heat. Heat is the major cause of decreasing the life of these
products.
5. Avoid assembly and use of the target equipment in conditions where the product's
temperature may exceed the maximum tolerance.
6. The supply voltage should not be exceedingly high or reversed. It should not carry noise
and/or spikes.
7. Keep this product away from other high frequency circuits.
5.1.2
Installation Notes
1. Reflow soldering is possible twice based on the conditions in
Soldering Profile.
according to this reflow profile.
2. Carefully position the products so that their heat will not burn into printed circuit boards
or affect the other components that are susceptible to heat.
3. Carefully locate these products so that their temperatures will not increase due to the
effects of heat generated by neighboring components.
4. If a vinyl-covered wire comes into contact with the products, then the cover will melt and
generate toxic gas, damaging the insulation. Never allow contact between the cover and
these products to occur.
5. This product should not be mechanically stressed or vibrated when reflowed.
6. To repair the board by hand soldering, follow the conditions set forth in this chapter.
7. Do not wash this product.
8. Refer to the recommended pattern when designing a board.
9. Pressing on parts of the metal cover or fastening objects to the metal will cause damage
to the unit.
