Applications
The EEE-HAJ330WAR is commonly used as an output bulk capacitor in low-voltage DC/DC converters and LDO regulators powering microcontrollers, FPGAs, and DSPs on 3.3V or 5V rails. Its 33µF capacitance provides effective ripple filtering in compact power stages where board space is at a premium. The part is also used in audio circuits, camera modules, and portable consumer electronics requiring stable bulk decoupling with a small SMD footprint.

Frequently Asked Questions
What capacitance and voltage rating does the EEE-HAJ330WAR provide for power supply filtering?
The EEE-HAJ330WAR offers 33µF of capacitance rated at 6.3V, making it suitable for output filtering on 3.3V or 5V rails in compact DC/DC converters. At these voltage levels, 33µF provides adequate bulk charge storage to suppress ripple and maintain load transient stability in low-power point-of-load designs.
How does the low-ESR characteristic of the EEE-HAJ330WAR benefit switching power supply designs?
Low ESR in the EEE-HAJ330WAR means less resistive voltage drop across the capacitor during switching transients, resulting in lower output ripple and reduced heat dissipation. For a 33µF capacitor on a 6.3V rail, a low-ESR part can reduce peak-to-peak output ripple by 30 to 50% compared to standard aluminum electrolytics under the same load conditions.
Is the EEE-HAJ330WAR compatible with reflow soldering for SMT assembly?
Yes, the EEE-HAJ330WAR is a surface-mount device designed for automated reflow soldering processes. Its SMD package follows standard land pattern recommendations, and the Panasonic HA series is specified to withstand the peak temperatures encountered in lead-free reflow profiles, typically up to 260°C for short durations.
When would you choose the EEE-HAJ330WAR over a ceramic MLCC of equivalent capacitance?
The EEE-HAJ330WAR is preferred over a 33µF MLCC when cost is a priority, since high-capacitance ceramic capacitors in X5R or X7R dielectric at 6.3V can cost 2 to 5 times more per unit. It is also selected when the PCB layout cannot accommodate the piezoelectric noise (acoustic noise) that large MLCC capacitors can generate under high ripple current conditions at switching frequencies above 100 kHz.
