EEU-FC1J391 Radial Electrolytic For Bulk Rail Stability

EEU-FC1J391 supports bulk filtering in DC power stages that run at elevated voltages. It helps reduce ripple and provides hold-up energy that can prevent nuisance resets and improve control-loop stability during load steps. This is a polarized aluminum electrolytic capacitor in a radial leaded can, making it well-suited for through-hole assembly and mechanically secure builds. Verified ratings include 390µF capacitance and 63V working voltage, giving meaningful bulk storage on higher-voltage rails without forcing a very large can. Use EEU-FC1J391 at DC bus segments, converter inputs, and auxiliary rails where rail droop can cause errors. Pair it with ceramics to handle fast edges and keep impedance low across frequency.
