Frequently Asked Questions
What capacitance and voltage rating does the ECA1HHG220 provide for power rail decoupling?
The ECA1HHG220 delivers 22 µF of capacitance at a 50 V rating, providing ample bulk decoupling for 12 V to 48 V DC power rails in industrial sensors, LED drivers, and consumer power supplies, with a ±20% tolerance typical of aluminum electrolytic capacitors.
How low is the leakage current of the ECA1HHG220, and why does it matter for battery-powered designs?
The ECA1HHG220 has a leakage current of only 0.011 mA at rated voltage, which at 50 V translates to just 0.55 mW of standby dissipation; this extremely low leakage prevents measurable battery drain in IoT nodes, handheld instruments, and portable 50 V bus designs where capacitor leakage accumulates over long sleep intervals.
For a compact power filter PCB, how small is the ECA1HHG220 body compared to larger electrolytic capacitors?
The ECA1HHG220 uses a 5 mm diameter radial body, which is among the smallest standard through-hole electrolytic package sizes available for 22 µF at 50 V; this allows it to be placed in tight PCB areas where 8 mm or 10 mm diameter capacitors of comparable value would not fit.
Is the ECA1HHG220 suitable for RoHS-compliant manufacturing and halogen-free processes?
Yes, the ECA1HHG220 is RoHS-compliant with a Pb-free designation and carries JESD-609 e3 coding indicating halogen-free materials, enabling its use in consumer electronics, medical accessories, and industrial boards that must satisfy EU RoHS directives and international environmental standards without requiring a waiver.
