NOTES:
1. In order to cool heat from an attenuator and to connect electrically when you attach the attenuator in a printed circuit a metal plate, reserve
soldering on back side of attenuator and reflowing (re-melting) solder with solder iron are recommended.
2.
In order to prevent diffusion of grounding conductor, please carry out solder processing of an attenuator quickly.
