Nippon Chemi-Con Corporation is a Japanese corporation that produces electrolytic capacitors. Nippon Chemi-Con was founded in 1931 by Toshio Satoh as the first electrolytic capacitors production in Japan.Their capacitors are used in many motherboards including DFI, and PSUs from Zippy Technology and Seasonic. Currently they are considered one of the best capacitor makers, along with Hitachi, and their reputation is a selling point for top of the line PSU brands like PC Power and Cooling, Enermax, BFG Technologies, Sea Sonic, Antec, SilverStone Technology and others.Today Nippon Chemi-Con still dominates the Global Aluminum Electrolytic industry as the largest producer and is poised to expand their business and influence in the capacitor industry with their many new developments including Conductive Polymer Capacitors, Ultra-Capacitors and Ceramic Capacitors.

A coil includes a plurality of coil conductor pieces, first and second cores and a case. The plurality of coil conductor pieces is made of a high magnetic permeability material. The first and second cores include through-holes in parallel. The through-holes allow penetration of the coil conductor pieces. The first core and the second core are stored in the case. At least one end part of one of the coil conductor pieces penetrating through the through-holes of the first core and the second core is coupled to an end part of the other coil conductor piece on the outside of the case. A coil conductor circling between the first and second cores is made up of the plurality of coil conductor pieces.

A capacitor includes a capacitor element having electrode foils on the anode side and the cathode side laminated via separators, connecting parts of terminal components being disposed inside a laminated portion of the electrode foils and the separators, the connecting parts being connected to the electrode foils on the anode side and the cathode side; and a case that includes a storage part storing the capacitor element and having an opening portion sealed by a sealing body, that has a crimped part crimped from the outside of the storage part toward a side surface of the capacitor element, and that holds the capacitor element with the crimped part. The case is crimped to form the crimped part while avoiding a position at which the electrode foils of the capacitor element in the storage part overlap with tip portions of the connecting parts of the terminal components.

Provided is an electrochemical capacitor which has low DC internal resistance, and which minimizes increase in the DC internal resistance due to a high temperature experience. The electrochemical capacitor is provided with a positive electrode having a positive electrode active material layer containing activated carbon, a negative electrode having a negative electrode active material layer containing a spinel-type lithium titanate, and a separator holding a non-aqueous electrolytic solution containing a lithium salt between the positive electrode active material layer and the negative electrode active material layer, a 100% discharge capacity of lithium titanate being set to within a range of 2.2 to 7.0 times a 100% discharge capacity of activated carbon. During charging and discharging of the electrochemical capacitor, only the area near the surfaces of lithium titanate particles are utilized, lowering the DCIR and improving the stability of the DCIR.

A capacitor module (2) including a case member having accommodating portions (14) that accommodate plural capacitors (4). A space (32) is included between an inner wall portion of the accommodating portions and the capacitor. A fixing member (16) is disposed in the space. The fixing member includes an annular portion (20) that surrounds a circumferential portion of the capacitor, and a wedge portion (22) that is formed on the annular portion in a direction of intersection with the annular portion. Any stress applied from the case member to the fixing member and a sealing curling portion can thereby be avoided. In addition, any load applied by vibrations to external terminals and an auxiliary terminal can be reduced, and the connection property and the fixing strength can be maintained.
