Nippon Chemi-Con Expanded PSG Series and PMA Series Conductive Polymer Aluminum Solid Capacitors with 25V High-capacitance Products and 35V Products
Nippon Chemi-Con has established a new technology for increasing the voltage of capacitors by reviewing conductive polymer materials and methods. Nippon Chemi-Con contributed to the downsizing and higher efficiency of power supplies by applying this technology and developing Conductive Polymer Aluminum Solid Capacitors with 25V and high capacitance, as well as 35V, for adapters, LED voltage booster circuits and small power supplies.
Radial lead type conductive polymer aluminum solid capacitors PSG Series has increased its capacitance by 40%, from 390µF to 560µF, for products sized φ10 x 11.5 Lmm with 25V rated voltage. This was achieved by adopting the new high-voltage technology, optimization of the element structure, and adoption of aluminum electrode foil with larger surface area. We will propose the Series for microinverters and adapters for USB PDs as products that contribute to downsizing and higher efficiency.
Nippon Chemi-Con has also succeeded in developing products with a rated voltage of 35V (conventionally up to 25V) using this technology and have already started mass production by adding them to the product lineup.
Nippon Chemi-Con has also developed products with a rated voltage of 35V for the resin-molded chip type conductive polymer aluminum solid capacitors PMA Series through the new high-voltage technology and optimization of the molding method.
The PMA Series uses our original technology to seal elements with a resin mold without using an aluminum case or sealing rubber. As a result, the product height has been reduced to 3.0 mm Max. These products contribute to the downsizing and thinning of power supplies, higher reliability and lower costs as an alternative for tantalum capacitors. Conventionally, products with a rated voltage up to 25V were commercialized. With the addition of 35V products, Nippon Chemi-Con will propose them for downsizing and higher efficiency of LED voltage booster circuits.
