Frequently Asked Questions
What voltage and capacitance ratings make ECEA0JKS331 suitable for low-voltage DC-DC converter output filtering?
The ECEA0JKS331 is rated at 330 µF and 6.3 V with a ±20% tolerance, making it well matched for filtering 3.3 V or 5 V DC-DC converter outputs. The 330 µF bulk capacitance provides sufficient charge storage to suppress output ripple voltage below acceptable limits in switch-mode power supply designs.
How does the 8 mm diameter radial package of ECEA0JKS331 affect PCB footprint and component spacing?
The 8 mm diameter radial body requires a circular keepout of at least 8 mm on the PCB, with standard radial lead spacing of 3.5 mm or 5.0 mm depending on the series variant. This is significantly larger than SMD equivalents, but allows easy hand soldering, through-hole wave solder processing, and replacement in service-intensive industrial or consumer electronics assemblies.
What is the typical leakage current specification for ECEA0JKS331 and why does it matter in low-power designs?
The ECEA0JKS331 specifies a leakage current of approximately 0.02 mA (20 µA) at rated voltage. In battery-operated or sleep-mode designs, this low leakage minimizes idle power consumption, extending battery life in IoT sensors, wearable devices, or remote monitoring equipment where the 6.3 V capacitor remains energized during standby periods.
