1. SCOPE AND MEANING OF “HIGH RELIABILITY GRADE”
This specification is applicable to WOUND STD INDUCTOR/MAGNETIC SHIELDED with a priority over the
other relevant specifications. Manufacturing places defined in this specification shall be TDK-EPC
Corporation Japan, and TDK Components USA. Inc.
“High Reliability Grade” means that TDK's LGJ Series Inductors provide an extended life Inductor that meets
or exceeds the electrical, mechanical and environmental performance standards from AEC Q200 Rev.D.
Details are referenced within section 7 of this specification. It also means that, in addition to our highest
quality Inductor, the customer will also receive access to an on-line Sigma Report (Enhanced Certificate of
Compliance) and internet based product authentication for each lot (which includes electrical characterization
data, and estimated product life, as well as anti-counterfeit packaging).
Additionally RFID (radio frequency identification) tags are available as an option.
EXPLANATORY NOTE:
For warranty information, please refer to section 14 of this specification.
