There are two kinds of polymer aluminum capacitors: the “surface mount” type (also known as H-Chip), which uses a multilayer aluminum foil structure, and the “Can” type (also known as V-Chip), which consists of a rolled aluminum structure.
Murata's H-Chip type (ECAS Series) is designed with a resin molded case structure, which utilizes multilayer aluminum foil for anode and solid conductive polymer for negative cathode.
Yes. The ECAS series utilizes multilayer aluminum foil for anode and solid conductive polymer for negative cathode.
ESR and impedance of Murata’s polymer capacitor are lower than other non-ceramic type capacitors because a multilayer structure design uses a conductive polymer for cathode; therefore, the ECAS series exhibits high performance for noise suppression, ripple absorption, and decoupling.
MLCCs offer the best overall solution in terms of size, volumetric capacitance, and low impedance.
Polymer capacitors extend the high capacitance offering.
Yes. Unlike MLCCs, polymer electrolytic capacitors have a marked polarity so proper placement on the PCB board is important.
No, because these components have polarity.
No. Murata's ECAS capacitors can be used without voltage derating because the electrolytic formation voltage is higher during manufacturing.
Operating temperature range is: -40℃ to 105℃
Capacitance range is 6.8µF to 470µF Rated voltage range is 2VDC to 16VDC
The ECAS series can only be reflowed soldered. Please check our specifications for applicable profiles and conditions.
No. The ECAS series are rated at MSL 3 and are packaged in special packaging and can be stored under normal warehouse conditions.
No. Polymer electrolytic capacitors do not exhibit “dc bias” characteristics shown by class 2 or 3 (high K) MLCC.
Yes. The ECAS series will follow Murata's conventional 18 digit GPN system.
Our strategy and goal have been to become a complete capacitor solution provider.
