NICHICON CORPORATION expanded its lineup of the PCH series of chip-type conductive polymer aluminum solid electrolytic capacitors that guarantee operation at 135°C to include rated voltages of 16V and 80V and case diameter of φ6.3. The new series will be exhibited at Power System Japan 2019, held at Makuhari Messe from Wednesday, April 17, to Friday, April 19.

Overview and Development Background

Demand for high heat resistance features is increasing, such as for use in the mounting of powertrain electronic control units (ECUs) in the engine compartment, as control boards have becoming increasingly integrated and diversified along with progress in automotive electronic technology as represented by advanced driver assistance systems (ADAS). Simultaneously, customers have increasingly asked for heat-resistant capacitors of smaller sizes and expanded rated voltages. In response to these market needs, NICHICON expanded the lineup of the 135°C compatible PCH series to include rated voltages of 16V and 80V DC and diameters of φ6.3.


NICHICON applied and further optimized the new technology it used to develop the PCH series to expand the lineup of the 135°C PCH series to include rated voltages of 16V and 80V and case diameters of φ6.3. These new offerings allow customers to select a product that meets their needs even at high temperatures, without compromising the features of conductive polymer aluminum solid electrolytic capacitors such as low equivalent series resistance (ESR) and high allowable ripple current.
