News Release

November 22, 2017

 NICHICON CORPORATION has added SPICE models and life expectancy calculations for its capacitors to the Companyís website. In addition, on November 22 we began providing 3D CAD*1 data (STEP and IGES file formats) that can be used with major CAD software. In this way, we aim to contribute to more efficient circuit design, helping to shorten design time and enhance design quality.


 In the automotive, construction, electrical equipment and other industries, 3D CAD models are used in simulation analysis and to shorten the amount of time needed for design. 3D CAD data is widely used for a variety of purposes: simulating heat generation and emission, as well as vibration and voltage; providing the ability to confirm interference with other parts. It is also used in prototyping products and molds. Requests for 3D CAD data for capacitors have increased recently, so we have responded by preparing this data as a technology support tool.


 To provide more accurate simulation analysis results, NICHICONís 3D CAD data faithfully portrays capacitors in fine detail. As a result, convection simulations can be performed to determine airflow around capacitors precisely while minimizing gaps.
 We have provided 3D CAD data for every size of chip type, radial lead type, snap-in terminal type and screw terminal type of aluminum electrolytic capacitoróa total of 326 varieties. Please download and make use of data for the size capacitor you need.

Other Support Tools

 In addition to the 3D CAD data, we are providing SPICE models (to enhance the precision of customersí circuit simulations) and life expectancy calculations (to allow estimates of a capacitorís estimated life expectancy).
 SPICE models are device models that can be used with circuit simulation software to reflect a capacitorís electrical characteristics, allowing circuit behavior to be reproduced accurately.
 Life expectancy calculations can be performed simply by entering the capacitor series name, the ambient temperature, applied ripple current and rated ripple current to determine estimated life.
 NICHICON CORPORATION is expanding a variety of technology support tools to assist customersí design and development efforts.

*1 3D CAD is a type of CAD used to design and draw industrial products and buildings, enabling a shaped object to be depicted and edited in three dimensions.
