Frequently Asked Questions
What capacitance and physical size does the ECA1VHG331 offer for power supply filter designs?
The ECA1VHG331 provides 330µF capacitance in a radial leaded package with a 10mm body diameter, making it a compact choice for through-hole power supply filter circuits. The 330µF value delivers effective bulk energy storage for smoothing rectified AC or switching regulator output ripple, with the 10mm diameter fitting standard PCB layouts for aluminum electrolytic capacitors in this capacitance range.
How does the leakage current specification of the ECA1VHG331 affect low-power circuit design?
The ECA1VHG331 has a specified leakage current of 0.1155mA, which in always-on power supply designs represents approximately 0.4mW of continuous power dissipation at typical operating voltages. For battery-powered equipment or ultra-low standby power supplies, this leakage level should be accounted for in standby power budgets. In most AC-mains or industrial applications, this leakage is negligible relative to load currents of hundreds of milliamps.
What dielectric material does the ECA1VHG331 use and how does it compare to polymer capacitors?
The ECA1VHG331 uses wet aluminum electrolytic dielectric (aluminum oxide with liquid electrolyte), which provides very high capacitance per unit volume compared to ceramic or film capacitors, but has higher ESR than polymer aluminum capacitors. Wet aluminum electrolytic capacitors like the ECA1VHG331 are cost-effective for bulk energy storage up to 330µF, while polymer types offer lower ESR (less than 20mΩ typical) for high-frequency switching converter output filters.
Is the ECA1VHG331 suitable for lead-free PCB assembly and what compliance codes does it carry?
Yes, the ECA1VHG331 is fully RoHS-compliant and REACH-compliant with a JESD-609 code of e3, confirming the terminal finish is compatible with lead-free soldering processes including SAC305 reflow and wave soldering. The radial leaded package withstands standard lead-free wave solder temperatures. These compliance codes make the ECA1VHG331 suitable for export to EU, UK, and global markets with strict environmental regulations on electronic component materials.
