Please note that the mounting holes marked “FG” in the outline drawing have a conductive pattern on the back side of the PCB.
We recommend using metal spacers for these mounting holes.
If a resin spacer is used, or if the customer’s housing is made of resin, EMI tends to increase and the power supply alone may not meet its terminal noise voltage specifications.
In such cases, additional noise-suppression components—such as a noise filter or ferrite core—may be required.
However, our products do not use insulating oil in transformers or other components, and therefore they do not contain PCBs.SP

• *Chemical Substances Control Law Class 1 Specified Chemical Substances
  These are chemical substances that are persistent, highly bioaccumulative, and exhibit long-term or chronic toxicity to higher-level predators. Regulations apply to their manufacture and import (in principle prohibited), restrictions on use, import restrictions on products designated by government ordinance, and obligations for Class-1 handlers to comply with standards and labeling requirements. PCBs were designated as a Class 1 Specified Chemical Substance on June 10, 1974.
