TAIYO YUDEN Expands Its Product Lineup of Bluetooth® 5 Compatible Wireless

TOKYO, May 11, 2020—TAIYO YUDEN CO., LTD., announced today the launch of wireless
communications modules EYSNCNZWW (9.6x12.9x2.0 mm) and EYSNSNZWW (3.25x8.55x1.00
mm). Both are compatible with Core Specification version 5.2, which is the latest version of
Bluetooth®*1 5.

These products support a direction-finding function that enables users to grasp location
information, and are most suitable for IoT-related devices that are required to be small and thin, such as
wearable devices, healthcare equipment, and handheld devices for logistics.
Mass production of the products will commence in May 2020.

Technology Background

IoT-related devices, such as wearable devices, are very small and therefore use a small-capacity battery
which necessitates that the device have extremely low power consumption. Most such devices use
Bluetooth® technology, which is a wireless communications standard with low power consumption. The
latest Bluetooth® Core Specification version 5.2 not only provides improved transmission speed and
expanded communication range, but also supports new features such as a sophisticated direction-finding
function, while retaining the low power consumption of previous versions.

We have now successfully commercialized two new Bluetooth® compatible wireless
communications modules, EYSNCNZWW and EYSNSNZWW, which support the direction-finding
function. These products allow the devices to indicate the location information of people and things in
indoor facilities such as warehouses and offices, which was previously not possible.

TAIYO YUDEN will continue to develop more multifunctional and reliable products to expand
our product lineup in response to market needs.
