Radial Lead Type Aluminum Electrolytic Capacitors GXM Series
Capacitors for communications infrastructure with
high temperature resistance and high capacitance developed
Nippon Chemi-Con has developed radial lead type aluminum electrolytic capacitors for power supplies used in high temperature environments such as communications infrastructure.

Capacitors used in next-generation communications infrastructure (5G base stations) require products with high temperature resistance, long life and high capacitance. This is because capacitors gain heat from use in closed environments and the need for maintenance caused by use in remote locations. As a high temperature resistant product for such applications, we commercialized the GXF Series. However, the new GXM Series has a maximum 1.7 times longer life and 61% higher capacitance compared to the GXF Series.
To cover a rated voltage range of 420 to 430V, frequently used in communication base stations, the rated voltage of the GXM Series supports up to 450V (the GXF Series supports up to 400V).

[Technical Features]
The GXM Series has achieved higher capacitance by adopting our newly developed electrode foil. Furthermore, the Series has achieved longer life by adopting liquid electrolyte with high endurance.

[Samples and Mass Production]
The GXM Series will be available as samples from January 2022 and production will begin in July 2022.
They will be produced at Chemi-Con East Japan Corp. Iwate Plant (a wholly owned subsidiary of Nippon Chemi-Con).
