To meet the increasing demand for extremely high-temperature resistant

capacitors in the automotive and industrial machinery fields, NICHICON

CORPORATION has developed the GYD series of conductive polymer hybrid

aluminum electrolytic capacitors with a rated operating temperature of 150°C.

The GYD series will be exhibited at CEATEC 2019, held at Makuhari Messe

from Tuesday, October 15, to Friday, October 18.

Overview and Development Background

NICHICON has previously released the GYA series (rated at 125°C for 4,000

hours) and the GYC series (rated at 135°C for 4,000 hours), and now offers a

rated temperature range of up to 150°C with the release of the GYD series.

The GYD series offers high performance and long life in extremely high-

temperature environments that our current lineup is unable to withstand.

Features

Conductive polymer hybrid aluminum electrolytic capacitors use both

conductive polymers and electrolytic solutions for electrolytes. Combining the

two types of electrolytes gives the GYD series characteristics of both conductive

polymers (low ESR, high heat resistance) and electrolytic solutions (oxide film

restoration).

We have achieved a guaranteed rating of 150°C in the GYD series by

making improvements in the materials and manufacturing process of the

conductive polymer, in addition to using an electrolyte that is compatible with

conductive polymers. The series has the longest guaranteed life in the industry

for capacitors sized φ8×10L and φ10×10L at 1,000 hours. Moreover, the GYD

series offers the highest ripple current for capacitors with a guaranteed rating of

150°C. Using the GYD series can contribute to miniaturization since it allows up

to 15 times the ripple current compared to the UBC series (aluminum

electrolytic capacitors).
