Murata
offers the
ECAS Series Polymer Aluminum Electrolytic Capacitors
for
low ESR
,
high capacitance
areas. This
ECAS
series has a resin molded structure, utilizing multilayer aluminum foil for anode, and solid conductive polymer for cathode. The
Murata
line also features
high capacitance
(6.8µF to 470µF with rated voltages from 2VDC to 16VDC),
low ESR
(6 to 70 mohms), good temperature characteristics, no need for voltage derating, and resistance to short circuits. In addition, the
Murata ECAS
series
Polymer Aluminum Electrolytic Capacitors
are available in a case size of 7.3mm x 4.3mm with three different thickness options.

Murata Electronics
' new series of
polymer aluminum electrolytic capacitors
(
ECAS
Series) 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.
The
Murata ECAS
series has a resin molded case structure, which utilizes 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 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). 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
MLCC
's, these
capacitors
do not exhibit drop with applied DC voltage. The operating temperature range is -40 to +105ºC, and all are RoHS compliant.
