Nippon Chemi-con Corp. now offers the HXE Series of surface-mount conductive polymer hybrid aluminum electrolytic capacitors rated for 16V to 35V. With a rated lifetime of 2,000 hours to 4,000 hours at 135°C, depending on the model, these devices are designed for use in high-temperature applications such as automotive equipment, telecommunications base stations, and so on.
Available capacitance values range from 47- to 470-μF. Depending on model number and ratings, dimensions range from a diameter of 6.3mm to 10mm and a height of 5.8mm to 10mm. These capacitors are specified to operate from -55 to +135 degrees C.
Ripple current ratings (at 125 degrees C) are: 1700 to 3400 mArms/100kHz, depending on capacitance, for 16V parts; 1400 to 3300 mArms/100kHz, depending on capitance, for 25V parts; and 1400 to 3300 mArms/100kHz, depending on capacitance, for 35V parts. ESR ratings range from 18 to 60 milliOhms maximum at 20 degrees C.
