Nippon Chemi-Con Developed KMQ Series Screw Terminal Type Aluminum Electrolytic Capacitors with 44mm Lower Profile and about Two Times Higher Ripple Current
Nippon Chemi-Con has developed the KMQ Series of Screw Terminal Type Aluminum Electrolytic Capacitors that feature a greatly reduced size and high ripple current for general-purpose inverter applications.
General-purpose inverters are widely used to obtain higher efficiencies in machine tools, industrial robots, and servo motors, and the market is expected to continue expanding.
Nippon Chemi-Con's KMQ Series realizes a significant size reduction as a smoothing capacitor for general-purpose inverters compared to the existing KMH Series. Comparing products with a rated voltage of 400V, the KMQ Series realizes a profile that is up to 44mm lower (a volume ratio that is up to 31% smaller) than the KMH Series, which has the same capacitance. In addition, a rated ripple current of up to twice the previous value has been achieved.
Technical Advantages
For development, Nippon Chemi-Con used the original high capacitance aluminum electrode foil with excellent thermal stability and optimized the structure to achieve a small size and high ripple current.
The KMQ Series helps customers reduce the size of their inverter systems.
Mass Production Schedule
Mass production of the KMQ Series has already started at Chemi-Con Fukushima Corp. (a 100% owned subsidiary of Nippon Chemi-Con) and was planned to be produced at overseas production bases (United Chemi-Con, Inc. in the United States and Chemi-Con (Wuxi) Co., Ltd. in China).
