Enhanced hybrid caps handle increased ripple current
Taiyo Yuden has launched the HVX(-J) and HTX(-J) series of conductive polymer hybrid aluminum electrolytic capacitors. These updated models offer a higher rated ripple current and a lower profile than previous HVX and HTX capacitors. They also meet the AEC-Q200 standard, ensuring reliability for automotive applications.
With increasing current demands in automotive power sources, there is growing need for hybrid capacitors that combine higher ripple current ratings, compact profiles, and a variety of sizes. The HVX(-J) and HTX(-J) series address this need, offering 36 different types. For example, the RAHTX331M1TFH0002JX achieves 3400 mA RMS at 135 °C—a 70% increase over the previous model’s 2000 mA RMS at the same temperature. Devices in the series are available in five package sizes, ranging from 8 mm in diameter and 10 mm in height to 12.5 mm in diameter and 13.5 mm in height.
The new hybrid capacitors offer rated voltages of 25 VDC to 63 VDC, capacitance values from 47 µF to 1000 µF, and high rated ripple currents at 135°C ranging from 2200 mA RMS to 4000 mA RMS. These performance characteristics make them well suited for noise suppression and power smoothing in automotive power-supply circuits, including control systems such as electric power steering and safety-critical applications like ADAS.
