POLYMER Aluminum Electrolytic Capacitors

Product catalog summary

Overview: Murata Manufacturing Co., Ltd.'s ECAS series of polymer aluminum electrolytic capacitors are engineered for low ESR, low impedance, and high capacitance. They feature multilayered aluminum foil for the anode and a solid conductive polymer for the cathode, ensuring stable temperature characteristics and superior performance in ripple absorption and transient response.

Key Features:

High capacitance and low ESR
Stable capacitance under various conditions
No voltage derating required
Surface mount construction
RoHS compliant and halogen-free
Capacitance range: 6.8 to 560μF
Operating temperature: -40°C to +105°C
Rated voltage: 2 to 16Vdc
ESR: 4.5 to 70mΩ

Applications: These capacitors are ideal for smoothing input-output current in power supply circuits and backup use over load changes in CPU environments. They are applicable in computers, digital AV, telecom, and more.

Specifications:

Operating temperature range: -40°C to +105°C
Capacitance tolerance: ±20%
Moisture resistance and endurance tests conducted under specified conditions

Design Support Tool: SimSurfing software is available for simulation, providing frequency responses and downloadable netlist and S-parameter data.

Cautions:

Avoid use in prohibited circuits such as time-constant or coupling circuits.
Ensure correct polarity to prevent damage.
Maintain operating voltage within rated limits.
Protect against excessive inrush current and ripple current.
Consider operating temperature limits and avoid exceeding them.
Handle with care during reflow soldering to prevent damage.

Storage Conditions:

The warranty term is two years when stored in a moisture-proof bag under specified conditions: room temperature of 5-30°C and humidity not exceeding 60%RH.
Avoid storing in environments with corrosive gases or high humidity to prevent leakage current and circuit damage.
After opening, confirm a dry state with a humidity indicator card. If necessary, bake the capacitors at 60°C for 168 hours.
The product meets MSL-3 standards.

Cautions for Use:

Complies with EU RoHS, restricting hazardous substances in electrical and electronic equipment.
Export control restrictions apply, prohibiting use in weapons or military applications without appropriate licenses.
Consult sales representatives before using products in high-reliability applications such as aerospace, medical, or disaster prevention equipment.
Product specifications are subject to change; verify with sales representatives before ordering.
Read all ratings and cautions to prevent issues like smoking or burning.
No ozone-depleting substances are used in manufacturing.

Note:

Product specifications are as of September 2014 and may change without notice.
Murata assumes no responsibility for conflicts related to intellectual property rights.
