Murata Electronics ECAS聚合物鋁質電解電容器

Murata提供ECAS系列的聚合物鋁質電解電容器，適用於低ESR、高電容的範圍。此ECAS系列採用樹脂模製結構，使用多層鋁薄膜做為陽極，並使用固態導電聚合物作為陰極。Murata系列亦具備高電容值（6.8 µF至470 µF，額定電壓2 VDC至25 VDC）、低ESR（4.5 mΩ至70 mΩ）、良好的溫度特性，無降電壓，且不怕短路。此外，Murata ECAS系列聚合物鋁質電解電容器的外殼尺寸為7.3 mm x 4.3 mm，並提供三種不同的厚度選項。

Murata Electronics的聚合物鋁質電解電容器系列（ECAS系列）擁有出色的等效串聯電阻 (ESR) 效能，遠勝過傳統的電解電容器，並可提供與多層陶瓷電容器 (MLCC) 類似的特性。ECAS系列大幅擴充了Murata的高電容值系列裝置，讓客戶有更多樣化的電容器解決方案可選。

470uF Capacitance

The ECASD40E477M006KA0 module achieves Murata's largest capacitance — 470µF, along with low 4.5mΩ ESR, in a D-size case (7.3mm x 4.3mm) with a maximum product height of 2mm. There is no DC bias characteristic of capacitance, and because temperature characteristics are also stable, the ECASD40E477M006KA0 excels in ripple absorption, smoothness, and transient response performance. This makes it suitable for the smoothing of the input-output current of various power supply circuits and the backup use over the load change of the CPU circumference.

The module also offers excellent ripple absorption, smoothness, and transient response performance compared to tantalum capacitors, as well as no risk of ignition.
