What are the key features of ECA1CM220?
- 22 µF at 16 V aluminum wet electrolytic in a compact 5 mm diameter radial body provides high capacitance density for cost-effective power rail decoupling
- Ultra-low leakage current of 0.00352 mA ensures minimal quiescent drain in battery-powered and low-standby-power circuits
- RoHS-compliant and Panasonic ECA series construction guarantees consistent ESR and long service life for high-volume consumer and industrial PCB assemblies
What is ECA1CM220 used for?
The ECA1CM220 is used in power supply output filtering, audio coupling, and signal decoupling circuits requiring a 22 µF 16 V radial electrolytic capacitor in through-hole designs. It suits consumer electronics such as audio amplifiers, TV power stages, and general-purpose industrial control boards where bulk capacitance on 5 V and 12 V rails is needed. Its 5 mm compact body also makes it a practical choice for space-efficient through-hole PCB layouts in legacy designs and high-volume production.

Frequently Asked Questions
What capacitance and voltage ratings does the ECA1CM220 provide and which supply rails does it suit?
The ECA1CM220 is rated at 22 µF capacitance and 16 V maximum working voltage, making it suitable for decoupling and filtering on 5 V, 9 V, and 12 V DC supply rails when operated with adequate voltage derating. Its 22 µF value provides sufficient bulk capacitance for output ripple reduction in linear regulators and low-frequency bypass in audio and industrial control circuits.
How low is the leakage current of the ECA1CM220 and why does it matter for battery-operated devices?
The ECA1CM220 has a specified leakage current of 0.00352 mA (3.52 µA), which is very low for a 22 µF aluminum electrolytic capacitor. In battery-powered devices operating in standby mode, this 3.52 µA leakage contributes negligibly to quiescent drain compared to typical microcontroller and radio currents, helping extend battery life in IoT sensors, remote controls, and portable instrumentation that use this capacitor on their power rails.
What PCB footprint does the ECA1CM220 require and how does its 5 mm body diameter affect board layout?
The ECA1CM220 uses a standard 2 mm lead pitch in its 5 mm diameter radial body, fitting a common 2 mm through-hole footprint found in high-volume consumer and industrial PCB layouts. The 5 mm diameter body requires approximately 5.5 mm of PCB pad clearance radius and typically stands 11 mm tall, allowing its use in designs with standard component height clearances of 12 mm or more above the board surface.
For an audio amplifier output stage, how does the ECA1CM220 compare to a film capacitor at the same 22 µF value?
A 22 µF film capacitor offers lower ESR and better high-frequency response than the ECA1CM220 aluminum electrolytic, but at 5–20x higher cost and 3–5x larger physical size for the same 16 V rating. The ECA1CM220 is preferred for low-frequency audio coupling above 20 Hz and power rail decoupling below 10 kHz where its higher ESR is acceptable, while film capacitors are reserved for precision audio and RF bypass roles where superior high-frequency performance justifies the cost premium.
