■Notes:
In order to achieve optimum jitter performance, the 0.1 μF capacitor between VCC and GND should be placed. It is also
recommended that the capacitors are placed on the device side of the PCB, as close to the device as possible and connected
together with short wiring pattern.
PROMOTION OF ENVIRONMENTAL MANAGEMENT SYSTEM
CONFORMING TO INTERNATIONAL STANDARDS
At Seiko Epson, all environmental initiatives operate under the
Plan-Do-Check-Action (PDCA) cycle designed to achieve continuous
improvements. The environmental management system (EMS)
operates under the ISO 14001 environmental management standard.
All of our major manufacturing and non-manufacturing sites, in
Japan and overseas, completed the acquisition of ISO 14001
certification.
ISO 14000 is an international standard for environmental
management that was established by the International
Standards Organization in 1996 against the background of
growing concern regarding global warming, destruction of
the ozone layer, and global deforestation.
WORKING FOR HIGH QUALITY
In order provide high quality and reliable products and services
than meet customer needs, Seiko Epson made early efforts towards
obtaining ISO9000 series certification and has acquired ISO9001 for
all business establishments in Japan and abroad. We have also
acquired IATF 16949 certification that is requested strongly by major
automotive manufacturers as standard.
►Explanation of the mark that are using it for the catalog
IATF 16949 is the international standard that added the
sector-specific supplemental requirements for automotive
industry based on ISO9001.
►Pb free.
►Complies with EU RoHS directive.
*About the products without the Pb-free mark.
Contains Pb in products exempted by EU RoHS directive.
(Contains Pb in sealing glass, high melting temperature type solder or other.)
►Designed for automotive applications such as Car Multimedia, Body Electronics, Remote Keyless Entry etc.
►Designed for automotive applications related to driving safety (Engine Control Unit, Air Bag, ESC etc ).
