Frequently Asked Questions
What capacitance and form factor does the ECA1CHG472 provide for power supply filtering?
The Panasonic ECA1CHG472 provides 4700 µF capacitance in a radial-leaded through-hole package with a 16 mm diameter. This large capacitance in a compact cylindrical aluminum electrolytic form factor is ideal for bulk energy storage and low-frequency ripple filtering in switching power supplies and motor drives.
How low is the leakage current of the ECA1CHG472 and why does it matter?
The ECA1CHG472 has a leakage current of just 0.752 mA, which minimizes wasted standby power in DC bus and filter capacitor banks. For a 4700 µF aluminum electrolytic capacitor, this low leakage helps maintain energy efficiency in UPS systems, motor inverters, and industrial power supplies where continuous operation is required.
What is the procurement lead time for the ECA1CHG472 and is it RoHS compliant?
The Panasonic ECA1CHG472 has a factory lead time of 21 weeks, so production planners should order early to avoid supply gaps. It carries a Pbfree Code of Yes and JESD-609 e3 classification, confirming full RoHS compliance and REACH compliance for environmentally regulated 4700 µF capacitor applications.
In which high-current applications does the ECA1CHG472's 4700 µF rating deliver the most benefit?
The ECA1CHG472's 4700 µF capacitance delivers the greatest benefit in motor drive DC bus capacitor banks, three-phase inverter filter stages, and audio amplifier power supplies where large energy reserves are needed to handle load transients. The 16 mm radial leaded package handles high ripple currents while maintaining compact PCB footprint in industrial and consumer power designs.
