Frequently Asked Questions
What capacitance and voltage rating does the EEEFK2A331AM provide and which power supply topologies does it suit?
The EEEFK2A331AM is rated at 330 µF and 100 V, storing approximately 1.65 mJ of energy. This combination suits DC bus bulk capacitors in flyback and forward converters with 85 V to 100 V DC rails, hold-up capacitors in power factor correction boost stages, and output filter capacitors in industrial 48 V to 100 V switching power supplies.
How does the EEEFK2A331AM's 0.33 mA leakage current specification affect use in precision power supply designs?
The 0.33 mA maximum leakage current means the capacitor will dissipate approximately 33 mW of continuous power at full 100 V rated voltage, which is acceptable for bulk storage roles but should be included in thermal budget calculations for power supplies with tight efficiency targets above 90%. In lightly loaded standby modes below 1 W, capacitor leakage can represent a significant fraction of total quiescent power.
What are the physical dimensions of the EEEFK2A331AM and how should it be mounted on a high-voltage PCB?
The EEEFK2A331AM measures 18 mm in diameter and 16.5 mm in height with a radial lead configuration. When mounting on PCBs with 100 V bus voltages, designers should maintain a minimum 2 mm creepage distance between the capacitor body and adjacent high-voltage traces, and ensure the mounting footprint accommodates the capacitor's lead spacing, typically 7.5 mm for 18 mm diameter aluminum electrolytics.
Is the EEEFK2A331AM suitable for replacement of older non-RoHS capacitors in service and repair applications?
Yes, the EEEFK2A331AM is RoHS compliant and REACH compliant, making it a direct replacement for older non-RoHS 330 µF 100 V radial aluminum electrolytics in service and repair scenarios. The JESD-609 e3 classification confirms halogen-free and lead-free construction, so it can be reflowed or hand-soldered into existing through-hole footprints without requiring PCB modifications or updated assembly temperatures.
