They should be reliable and robust, if possible more and more compact with increasing performance: The demands on electronic components in general and passive components in particular are constantly growing. With its latest polymer hybrid capacitors called HXF, Nippon Chemi-Con offers the best of two capacitor worlds.
Hybrid capacitors achieve higher voltage ranges with a combination of solid (polymer) and liquid electrolytes in addition to the high stability and power handling capabilities of polymer technology. In direct comparison to aluminum electrolytic capacitors with liquid electrolyte (in short: aluminum electrolytic capacitor), the significantly higher current-carrying capacity and longer service life stand out. Compared to ceramic capacitors, they prove to be more capacitance-stable under thermal or voltage load.
With polymer hybrid capacitors such as the new HXF from Nippon Chemi-Con, long life meets stable electrical parameters over a wide range of applications. Also on the plus side: the low equivalent series resistance ESR, very high ripple currents and very high temperature resistance as well as the self-healing property. The latter is also found to a certain extent in pure polymer capacitors, but is accompanied by a loss of capacitance, since damaged areas in the dielectric are electrically “isolated” but no longer contribute any capacitance. The liquid electrolyte in the hybrid capacitor means that even damaged areas in the dielectric can be made electrically usable again by oxidation. (1)
The HXF series from the world market leader NCC with the latest film technology enables even higher ripple currents for particularly demanding applications. Even at increased maximum temperatures of up to 135 degrees Celsius (even 150°C for a short time), the service life continues to be 4,000 hours. The design has been slimmed down even further: in addition to improved load potential, the polymer hybrid HXF thus also provides the opportunity for the much desired miniaturization. Polymer hybrid capacitors from NCC naturally meet the requirements of AEC-Q200 of the Automotive Electronic Council.
Key facts about polymer hybrid capacitors HXF from Nippon Chemi-Con:
- High temperature resistance up to 135°C (briefly also up to 150°C)
- Long life at high temperature load (4,000h at 135°C)
- Ripple currents up to 3.3A
- Compact SMD design (8x10mm or 10x10mm)
- 25Vdc – 63Vdc
- 33µF – 330µF
- Suitable for harsh climatic conditions (85°C/85%rH bias humidity)
- AEC-Q200 compliant
The use of polymer hybrid capacitors will continue to increase: The advantages are obvious, the call for compact design, high reliability and performance makes the hybrid irreplaceable and inevitable. In the end, there is a clear trend towards hybrid capacitor technology. But: depending on the application, the aluminum electrolytic capacitor, the ceramic capacitor or the pure polymer capacitor can also offer the appropriate parameters. The technical support of the distributor helps to individually select and dimension the electronic components suitable for your applications.
