Applications
The ECA1JHG470 is used as a bulk decoupling and power supply filtering capacitor in consumer electronics, industrial control boards, and audio amplifier power stages. Its 47µF value is appropriate for smoothing rectified DC rails in low-power switching converters and linear regulators operating at voltages within the capacitor's rated range. The compact 6.3mm diameter body also fits standard through-hole PCB layouts with tight component spacing in set-top boxes, LED drivers, and small embedded power supplies.

Frequently Asked Questions
What is the capacitance value of the ECA1JHG470 and what voltage rating does it carry?
The ECA1JHG470 has a capacitance of 47µF. The voltage rating is encoded in the part number's series designator and corresponds to 6.3V for the ECA1JHG series from Panasonic. This 47µF/6.3V rating makes it suitable for decoupling and filtering on low-voltage rails in 3.3V and 5V digital circuits, USB power lines, and audio pre-amplifier supply nodes.
How does the leakage current of the ECA1JHG470 compare to typical aluminum electrolytic capacitors?
The ECA1JHG470 has a leakage current of approximately 0.03mA (0.02961mA). This is within the normal range for a 47µF aluminum wet electrolytic capacitor but is notably low for its capacitance class, making it preferable in battery-powered designs where standby current budgets are tight. Capacitors with higher leakage would drain a 100mAh battery noticeably faster over hours of idle operation.
What are the physical dimensions of the ECA1JHG470 and how does its body size influence PCB layout?
The ECA1JHG470 has a cylindrical body with a diameter of 6.3mm and a radial lead spacing of 2.5mm, which is a standard pitch compatible with most through-hole PCB footprint libraries. The 6.3mm diameter keeps the capacitor compact, allowing it to be placed in rows with minimal spacing between adjacent components on densely populated PCBs in consumer electronics or small power supply modules.
Is the ECA1JHG470 suitable for use in a 5V linear regulator output filter, and why?
Yes, the ECA1JHG470 is well suited for a 5V linear regulator output filter using 47µF of capacitance at 6.3V rating. However, designers should confirm that the peak output voltage stays below the rated voltage with adequate derating (typically 20% margin), so a 5V output would require a capacitor rated at minimum 6.3V, which this device satisfies. The 47µF value provides good high-frequency bypassing for regulators in the 100mA to 500mA current range.
How does aluminum wet electrolytic construction in the ECA1JHG470 differ from ceramic or film capacitors for power filtering?
The ECA1JHG470 uses a wet aluminum electrolytic construction which achieves 47µF capacitance in a 6.3mm body at very low cost per microfarad compared to ceramic X5R or X7R capacitors of the same value. Aluminum electrolytic capacitors have higher ESR (typically 0.5 ohm to 5 ohms) than ceramic types, which makes them less ideal for high-frequency decoupling above 1MHz but perfectly adequate for bulk energy storage and low-frequency ripple filtering on rectified supply rails below 100kHz.
