ECAS Series Polymer Aluminum Electrolytic Capacitors

ECAS series offers low ESR, high capacitance, polymer cathode technology

ECAS Series Polymer Aluminum Electrolytic Capacitors Murata Electronics' ECAS series polymer aluminum electrolytic capacitors are ideal for low ESR, high capacitance applications in a variety of commercial and industrial markets. Utilizing innovative design and manufacturing processes, the ECAS series provides a high level of performance allowing circuit designers to achieve excellent noise suppression, ripple absorption, and output smoothing in power management applications.

Polymer capacitors exhibit strong equivalent series resistance (ESR) performance compared to traditional electrolytic capacitors and provide similar characteristics when compared to multi-layer ceramic capacitors (MLCCs). The ECAS series allows Murata to greatly expand its high capacitance offerings, giving customers a full range of capacitor solutions. Markets for the ECAS series capacitor include computer, digital audio visual, and telecom for overall power management.

The ECAS series has a resin molded case structure, which utilizes multilayer aluminum foil for the anode and solid conductive polymer for the cathode. This surface mount design can be soldered using traditional reflow methods. The offered capacitance range is 6.8 µF to 470 µF with rated voltages from 2 VDC to 16 VDC. It is available in a case size of 7.3 mm x 4.3 mm with three different thickness options. The high capacitance value and low ESR lead to low impedance at high frequency (up to 500 kHz). This provides excellent noise suppression, ripple absorption, and decoupling abilities on power lines. In addition, the ECAS series offers capacitance stability at high operating frequencies and temperatures. Unlike MLCCs, these capacitors do not exhibit drop capacitance with applied DC voltage.

The operating temperature range is -40°C to +105°C, and all are RoHS compliant.
