Key Features
- 2200 µF capacitance at 50 V rating delivers high bulk energy storage for power supply ripple filtering and holdup circuits
- 16 mm diameter radial leaded package ensures compatibility with standard through-hole PCB footprints and wave-soldering processes
- Maximum leakage current of 1.1 mA and ±20% tolerance meet AM Series reliability standards for long-service-life applications
Applications
The Panasonic ECA1HAM222X is used as a bulk filter and energy storage capacitor in switched-mode power supplies, motor drive inverters, and industrial control equipment operating from 50 V DC bus rails. Its 2200 µF capacitance provides effective ripple attenuation and holdup time extension in AC-DC converter output stages and DC-link circuits. The radial through-hole package suits high-current applications where leaded capacitors offer lower inductance mounting than SMD alternatives of equivalent value.

Frequently Asked Questions
How much ripple current and holdup time can the ECA1HAM222X provide in a 50 V power supply output stage?
With 2200 µF of capacitance at 50 V, the ECA1HAM222X can deliver significant holdup energy; for example, a 50 V rail with 2200 µF holds up approximately 2.75 J of stored energy, supporting a 10 A load for about 5.5 ms from 50 V down to 40 V. The AM Series construction also allows rated ripple current handling at 85°C or 105°C depending on the specific sub-variant, making it practical for power supply output filters in industrial equipment.
What PCB footprint does the ECA1HAM222X require and how does the 16 mm body diameter affect layout spacing?
The ECA1HAM222X uses a radial through-hole mount footprint with a 16 mm body diameter, which requires a minimum 17 mm to 18 mm clearance circle on the PCB to accommodate the capacitor body and lead spacing. Standard lead pitch for 16 mm diameter electrolytic capacitors is typically 7.5 mm, which must be matched in the PCB footprint to avoid stress on the leads after wave or hand soldering.
Under what conditions does the 1.1 mA leakage current of ECA1HAM222X become a design concern?
The 1.1 mA maximum leakage current of the ECA1HAM222X becomes a design concern in battery-backed or low-standby-power systems where the capacitor remains charged but the main load is disconnected. In a 50 V holdup circuit with 2200 µF, a 1.1 mA leakage rate will discharge the capacitor at roughly 0.5 V per second under no-load conditions, which may reduce effective holdup time and increase standby power consumption in energy-efficient designs.
