Key Features

  • 330 µF capacitance at 6.3V rating provides high-bulk energy storage in compact SMD package for power rail decoupling
  • FK Series ultra-low ESR aluminum electrolytic design reduces ripple voltage in switching power supply output stages
  • 7.7 mm height SMD radial can enables automated pick-and-place assembly on standard SMT production lines
  • RoHS and REACH compliant Pb-free construction with leakage current as low as 0.021 mA at rated voltage

Applications

EEEFKJ331XAP is used as bulk output capacitor in 5V and 3.3V DC-DC converter designs, providing 330 µF energy storage to handle load transients and reduce output ripple below 50 mV. It is also placed on power rails of embedded systems, IoT gateways, and industrial controllers where SMD aluminum electrolytic capacitors must fit automated SMT reflow assembly and deliver stable supply decoupling under 6.3V.

Frequently Asked Questions

What capacitance and voltage rating does EEEFKJ331XAP provide for power supply designs?

EEEFKJ331XAP provides 330 µF capacitance rated at 6.3V DC, with a ±20% capacitance tolerance. This bulk storage is sufficient to handle 50 mA load steps with less than 15 mV voltage droop on a 3.3V rail when used as the main output capacitor in low-voltage DC-DC converters.

How does the FK Series SMD package height affect PCB assembly in low-profile enclosures?

EEEFKJ331XAP stands 7.7 mm tall in a radial-can SMD footprint, which fits standard pick-and-place machines rated for components up to 10 mm height. Its SMD termination eliminates through-hole drilling, saving PCB fabrication time and enabling placement in enclosures with internal clearances as small as 9 mm.

What is the leakage current specification of EEEFKJ331XAP at full 6.3V rated voltage?

EEEFKJ331XAP has a leakage current of approximately 0.021 mA (20.8 µA) at 6.3V, which is well within acceptable limits for always-on power rail decoupling in battery-powered IoT devices where standby current budgets are typically under 1 mA.

When is EEEFKJ331XAP preferred over a ceramic MLCC for output filtering in a 5V switching regulator?

EEEFKJ331XAP is preferred when 330 µF capacitance is needed and PCB area is too limited for multiple 100 µF ceramic capacitors. Achieving 330 µF with X5R MLCCs would require at least 4 components, while EEEFKJ331XAP consolidates that into 1 SMD part, reducing BOM cost by up to 60% at the cost of higher ESR compared to ceramic alternatives.
