Inspiring our company name, dielectric (Japanese: yuden) materials play a key rolein determining MLCC features and barium titanate is mainly used at the moment.
TAIYO YUDEN is a rare MLCC manufacturer in that we make full use of sophisticated technology, such as synthesizing raw materials and particle control, todevelop materials by ourselves. TAIYO YUDEN continues to this day to uphold theMastering electronic components
with inimitable technology
TAIYO YUDEN has continued to develop and manufacture capacitors as the companyʼs main product since its foundation.
Our smaller, thinner, high-capacity, and highly-reliable multilayer ceramic capacitors (MLCC)
play a major role behind the scenes as components indispensable to the electronic devices that we all use in everyday life.
It is our material and lamination technologies, cultivated in the process of MLCC advancement,
which form the nucleus of TAIYO YUDENʼs superior technical skills,
and they are widely applied also to the development and manufacturing of electronic components besides MLCC.

principle of the founder that the “commercialization of products should start fromthe development of materials.”

Lamination technology (Processing technology)
We have continued to make MLCCs smaller but with higher capacity, helping thefurther miniaturization and functionality of electronic devices. The amount ofelectricity stored by an MLCC increases depending on the dielectric layers, so
lamination technology, which examines how many layers thinned to the maximum
can be piled up precisely, is the key to miniaturization and capacity enlargement.
TAIYO YUDEN has sophisticated this technology and realized laminate structuresof 1,000 or more layers in a tiny MLCC just a few millimeters tall.

SDGs Case Study
Reducing energy through miniaturizationof electronic components

Efforts to reduce GHG emissions

As a main product of TAIYO YUDEN, we are conducting research
on a daily basis to further miniaturize while increasing thefunctionality of multilayer ceramic capacitors (MLCCs). There is a
growing need for MLCCs to evolve in concert with the increasing
miniaturization, functionality and power-saving qualities ofelectronic devices.
While supporting the advancement of electronic technology
by miniaturizing MLCCs, TAIYO YUDEN has been striving to makea social contribution by cutting the amount of used raw materials
and packaging materials and the amount of energy used for
production and transportation.

In order to realize carbon neutrality by 2050, TAIYO YUDEN
has set a mid-term goal to reduce GHG emissions. To achieve
this goal, we are endorsing the TCFD (Task Force on
Climate-related Financial Disclosures) recommendations anddisclosing information in line with TCFD recommendations
based on the implementation of energy conservation, energy
creation, and energy recovery, and we are also installing solar
panels at domestic and overseas sites, etc. We will convert
100% of the electricity used at the R&D Center to renewableenergy from the 2024 ﬁscal year.

SDGs Targets◎Strengthen core technologies tomake our core business grow◎Create solutions to solve social issues◎Strengthen measures to address
climate change◎Use resources effectively andcontribute to create recycling society◎Achieve health-oriented management
and work style reforms at safety ﬁrst
workplace◎Train and develop human resources
