该系列还提供噪声抑制和纹波吸收功能、电源线去耦能力,以及在较高工作频率和温度下的电容稳定性。不同于MLCC,该系列电容器的电容量不会因施加了直流电压而下降。Murata ECAS聚合物铝电解电容器的封装尺寸为7.3mm x 4.3mm,有三种不同的厚度选择。
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.
