Hybrid capacitors boost e-mobility, reliability and lifespan
The Panasonic Industry ZTU series of hybrid capacitors targets the most demanding automotive conditions, while the ZUU series pushes the envelope on capacitance and ripple current for high-power circuits.
The ZTU and ZUU series conductive polymer hybrid aluminum electrolytic capacitors are designed to enhance reliability in advanced e-mobility platforms. These capacitors combine the low ESR of conductive polymer technology with the stability and long life of hybrid aluminum electrolytics, delivering strong performance under harsh thermal and electrical stress.
Wide coverage for automotive and industrial power rails:
- ZTU rated voltages: 25V and 35V
- ZUU rated voltages: 25V, 35V, 50V and 63V
Across both series, capacitance values span from 120µF up to 1000µF depending on series and voltage rating, supporting functions such as dc-link buffering, power-rail smoothing, and transient suppression in e-mobility and industrial power systems.
Both series are specified for high endurance: 4,000 hours at 125°C and 4,000 hours at 135°C according to datasheet endurance conditions, enabling long service life in high-temperature environments.
In advanced mobility applications, ZTU and ZUU capacitors help to stabilize dc links and power rails despite heat, vibration, and high ripple currents. The hybrid construction delivers low impedance characteristics suited to demanding power stages, and their surface-mount form factor supports dense layouts where board area and weight are at a premium.
Both families are offered in versions intended for demanding mechanical environments. Vibration-proof variants are available, with Panasonic test conditions indicating maximum acceleration up to 30G for the vibration-proof capacitors.
| Series | Capacitance | Ripple Current | Miniaturization |
| ZTU | 1.7x larger than entry-level hybrid series Example 330µF → 560µF, φ10x10.2mm | 1.8x 2900mA → 3500mA | φ10×10.2 → φ8×10.2 Smaller case size for same capacitance |
| ZUU | Largest capacitance series up to 1000µF | Largest ripple current series up to 6.1A | Saves cost and space with 1-to-many replacements |
