Product News October 2, 2014

NICHICON is expanding the CZ Series (UCZ) of chip type aluminum electrolytic capacitors by adding a low-temperature ESR (*1), and a high-volume φ12.5mm to φ18mm product to the lineup. This product is mainly intended for use in automotive electronics.

The CZ Series will be on display at the CEATEC JAPAN 2014 exhibition to be held at Makuhari Messe October 7–11 (Tuesday–Saturday).

Background of Development

In recent years, there has been a rapid shift toward placement of ECUs (*2) and other onboard control units in or near the engine compartment. In addition to exposing the unit to engine compartment temperatures, in very cold climates the temperature could fall below the operational minimum. We also recognize the demand from an environmental perspective for more compact and efficient units.

Parts used in the engine compartment must also be compact and able to withstand high temperatures, have a long lifespan, stable at cold temperatures and capable of withstanding high ripple currents. We have added to the CZ Series of low-temperature ESR capacitors to meet those demands.

Main Features

The CZ Series is notable for low-temperature ESR for operability in the particularly harsh temperature environment presented by onboard use. This addition to our size lineup provides a high-volume option of up to a maximum of four times the capacitance value of our existing UE Series of 125°C-rated chip capacitors employing high capacitance electrolytic foil. Also, using a new separator paper and electrolytic fluid with a newly-developed vapor deposition film optimizes the parts composition, which in turn permits the industry’s most stable low-temperature ESR performance for its size.
