What are the key features of ECA1EHG331?
- 330 µF capacitance in a compact 8 mm diameter radial package enabling high-density PCB layouts in space-constrained power supply designs
- Ultra-low 0.0825 mA leakage current reducing idle power draw in standby and low-power applications compared to higher-leakage alternatives
- RoHS-compliant (Pbfree) wet aluminum electrolytic construction with 7-year YTEOL for sustained production availability
What is ECA1EHG331 used for?
The ECA1EHG331 suits low-power DC-DC converter output filters, portable device battery management circuits, and audio pre-amplifier power rails where 330 µF of bulk capacitance in an 8 mm footprint minimizes board area. Its very low leakage of 0.0825 mA also makes it appropriate for energy-harvesting modules and standby power supplies where minimizing quiescent drain is a priority.

Frequently Asked Questions
How does the ECA1EHG331's 0.0825 mA leakage current compare to similar 330 µF capacitors, and why does it matter in low-power designs?
The ECA1EHG331's 0.0825 mA leakage is significantly lower than many standard 330 µF aluminum electrolytics that can reach 0.2 mA to 0.5 mA. In a battery-powered device running from a 3.3 V rail, this translates to about 0.27 mW of wasted power versus up to 1.65 mW for higher-leakage alternatives, extending battery life meaningfully in always-on applications.
For a 5 V switching regulator output filter, what does 330 µF in an 8 mm diameter package enable for PCB layout?
The ECA1EHG331's 8 mm diameter footprint is smaller than the 10 mm or 12.5 mm bodies often used for 330 µF to 470 µF capacitors, allowing tighter component spacing around the regulator IC. This enables compact power supply sections in portable devices and single-board computers where minimizing the distance between the regulator and bulk filter capacitor reduces output impedance at low frequencies.
What procurement lead time should engineers plan for when using the ECA1EHG331 in a production design?
Panasonic quotes approximately 21 weeks factory lead time for the ECA1EHG331, and its YTEOL rating of 7 years indicates sustained availability through at least the mid-2030s. Design teams should build at least 6 months of safety stock into initial BOM planning to avoid production line stoppages during high-demand periods for standard aluminum electrolytic capacitors.
