Applications
The ECA1CHG222 is primarily used as a bulk decoupling and energy storage capacitor on the output stage of AC-DC power supplies, DC-DC converters, and motor drive inverters where 2200 µF of capacitance smooths rectified voltage and suppresses low-frequency ripple. Its large capacitance also makes it suitable for hold-up circuits in industrial equipment that must maintain voltage for tens of milliseconds during brief power interruptions. Audio amplifier power supply rails benefit from the 2200 µF bulk capacitance to reduce low-frequency hum and improve transient current delivery to the amplifier stage.

Frequently Asked Questions
What capacitance and voltage rating does the ECA1CHG222 carry, and what does the part number encode?
The ECA1CHG222 provides 2200 µF of capacitance. In Panasonic's ECA series naming convention, 'G' in the part number designates the voltage rating — specifically 16 V for the ECA-1C series. The full specification is therefore 2200 µF at 16 V, with a maximum leakage current of 0.352 mA, making it a high-capacitance, low-voltage bulk filtering capacitor. The radial 12.5 mm body fits standard PCB layouts.
How does the 12.5 mm diameter body of ECA1CHG222 affect PCB layout for a switching power supply?
The 12.5 mm diameter requires a corresponding footprint with lead spacing typically at 5 mm (0.197 inch), and the body height varies with the exact ECA variant but is commonly 20 mm to 25 mm tall. Designers must ensure at least 0.5 mm clearance around the body for neighboring components and adequate airflow. For a 16 V, 2200 µF bulk output capacitor in a compact power supply, this is one of the smallest radial through-hole footprints available at this capacitance.
Can ECA1CHG222 be used in a motor drive DC bus filter, and what ripple current should designers assume?
Yes, the ECA1CHG222 is suitable for DC bus filtering in small motor drives operating at bus voltages below 16 V. Aluminum electrolytic capacitors of this series typically handle ripple currents in the range of 500 mA to 1000 mA at 120 Hz and 105 °C, though the exact rated ripple current for ECA1CHG222 must be confirmed in the Panasonic datasheet. Exceeding the ripple current limit causes internal heating, increasing ESR and shortening the 2200 µF capacitor's operational life.
Is ECA1CHG222 compliant with RoHS and REACH environmental regulations for export to Europe?
Yes, the ECA1CHG222 carries both RoHS-compliant and REACH-compliant designations, confirmed by its Panasonic JESD-609 code e3 (lead-free). This means it contains no restricted substances above the thresholds defined under EU RoHS Directive 2011/65/EU and can be freely imported and sold in the European Union. The lead-free radial terminations are also compatible with standard SAC305 reflow and wave-solder profiles used in RoHS manufacturing lines.
How does the leakage current of ECA1CHG222 compare to film capacitors for precision hold-up applications?
The ECA1CHG222 has a maximum leakage current of 0.352 mA, which is typical for wet aluminum electrolytic capacitors and significantly higher than the sub-nanoampere leakage of equivalent film capacitors. For hold-up applications where the 2200 µF capacitor must maintain voltage for 20 ms to 50 ms during a power dropout, this leakage is negligible. However, in precision analog circuits or ultra-low-power sleep modes where even microampere-level leakage matters, a film capacitor would be preferred over this electrolytic.
