What are the key features of ECEA1VKS330?
- 33 µF capacitance at 35 V rating in a compact 8 mm radial package for board-space-constrained designs
- Wet aluminum electrolytic dielectric with low 0.01155 mA leakage current for stable long-term energy storage
- ±20% capacitance tolerance meets standard filtering and decoupling requirements across industrial temperature ranges
- RoHS-compliant (Pb-free, JESD-609 e3) supporting lead-free wave and reflow soldering processes
What is ECEA1VKS330 used for?
The ECEA1VKS330 is commonly used as a bulk decoupling and energy-storage capacitor in power supply output stages where 35 V rail voltages and 33 µF capacitance provide adequate hold-up time and ripple attenuation. Its radial through-hole form factor makes it well suited for industrial control boards, audio amplifier power rails, and consumer electronics where axial or leaded mounting is preferred over SMD alternatives. The KS series construction also supports general-purpose filtering applications in motor drives and switching regulators operating up to the 35 V rated voltage.

Frequently Asked Questions
What capacitance and voltage rating does the ECEA1VKS330 provide for power supply filtering?
The ECEA1VKS330 provides 33 µF capacitance rated at 35 V DC. This combination delivers effective bulk energy storage and low-frequency ripple attenuation in linear and switching power supplies, and supports hold-up times sufficient for typical industrial and consumer control circuits operating on 24 V or 28 V rails.
How does the 8 mm body diameter of ECEA1VKS330 influence PCB layout choices compared to smaller electrolytic capacitors?
The 8 mm diameter radial body requires a footprint with lead spacing matched to that can size, typically 3.5 mm pitch, and a 8 mm pad-clearance keepout. Compared to a 5 mm or 6.3 mm diameter alternative with the same 33 µF value, the ECEA1VKS330 occupies slightly more board area but offers lower ESR at 35 V, making it preferable where current handling exceeds 100 mA ripple.
What is the leakage current of ECEA1VKS330 and when does it become a design concern?
Specified leakage is 0.01155 mA at rated voltage. In high-impedance sensing or precision analog circuits where bias currents are in the nano-amp range, even this modest leakage can introduce DC offset errors. For such applications, a film or ceramic capacitor rated for 35 V would be a better choice, while ECEA1VKS330 remains ideal for low-impedance bulk filtering.
Is ECEA1VKS330 compliant with RoHS and lead-free assembly standards?
Yes, ECEA1VKS330 carries a Pb-free code of Yes and JESD-609 code e3, confirming full RoHS compliance. It is compatible with lead-free wave-solder processes at temperatures up to 260 °C, meeting EU RoHS directives and supporting green manufacturing for consumer, industrial, and telecommunications equipment.
