Frequently Asked Questions
What is the capacitance and voltage rating of the Panasonic ECA1HM220?
The ECA1HM220 provides 22 µF of capacitance at a rated voltage of 50 V. This combination is well suited for power-supply decoupling and bulk energy storage in circuits operating from 12 V to 48 V rails, providing adequate voltage headroom while maintaining a compact 5 mm diameter radial footprint on the PCB.
How low is the leakage current of the ECA1HM220, and why does it matter for precision circuits?
The ECA1HM220 specifies a maximum leakage current of 0.011 mA, which is very low for a 22 µF aluminum electrolytic capacitor. In precision analog circuits, timer networks, or sample-and-hold stages, excessive leakage can cause voltage drift and measurement errors, so a 0.011 mA maximum helps preserve signal integrity and long charge retention.
Which PCB assembly processes are compatible with the ECA1HM220 package?
The ECA1HM220 uses a radial-leaded 5 mm diameter body, compatible with through-hole PCB assembly and standard single-sided auto-insertion equipment. Its JESD-609 e3 moisture sensitivity code and RoHS-compliant lead-free (Pb-free) construction allow it to pass through standard reflow and wave solder processes without special handling precautions.
For a 48 V industrial power supply design, how does the ECA1HM220 compare to a higher-voltage 63 V variant?
At a 48 V rail, the ECA1HM220 rated at 50 V leaves only a small 2 V headroom, which is insufficient when accounting for transient spikes common in industrial switching supplies. A 63 V-rated variant would provide at least a 15 V margin above the 48 V rail, substantially reducing the risk of capacitor overvoltage failure and improving long-term reliability in those applications.
