New high capacitance, conductive polymer capacitors expand Murata's already extensive product offerings.
Murata announces the ECAS series of polymer aluminum electrolytic capacitors. This is the first non-ceramic based capacitor product for Murata to be released into full production volume and is the result of Murata's purchase of Showa Denko K.K.'s (SDK) conductive polymer capacitor business. 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, utilizing multilayer aluminum foil for anode and solid conductive polymer for negative cathode. This surface mount design can be soldered using traditional reflow methods.
The offered capacitance range is from 6.8uF to 470uF with rated voltages from 2VDC to 16VDC. It is available in a case size of 7.3mm x 4.3mm with three different thickness options. The high capacitance value and low ESR lead to low impedance at high frequency (up to 500kHz) thus providing excellent noise suppression, ripple absorption and decoupling abilities on power lines. In addition, the ECAS series offers capacitance stability at high operating frequencies and high temperatures.Unlike MLCCs, these capacitors do not exhibit capacitance drop with applied DC voltage.
The operating temperature range is -40°C to 105°C and all are RoHS compliant.
With the addition of the new ECAS series, Murata now provides a line of polymer aluminum electrolytic capacitors to complement Murata's existing MLCC products as well as a variety of ceramic capacitors in a wide range of voltages.
