Key Features
- 100 µF capacitance at 6.3 V rating provides robust bulk decoupling for low-voltage power rails
- 105 °C maximum operating temperature extends service life in high-temperature SMD applications
- HA series construction delivers long rated life, typically 2,000 hours at 105 °C for reliable operation
- Compact SMD form factor suits automated reflow assembly on space-constrained PCBs
- Low equivalent series resistance (ESR) supports effective ripple-current filtering in switch-mode power supplies
Applications
The EEE-HA0J101WR is widely used as an output bulk decoupling capacitor on 5 V and 3.3 V switch-mode power supply rails in consumer electronics, set-top boxes, and industrial control boards. Its 105 °C rating and long operational life make it a reliable choice for input filter and hold-up capacitance in power-conversion stages of flat-panel displays, LED drivers, and compact embedded computing modules.

Frequently Asked Questions
What are the key electrical ratings of the EEE-HA0J101WR, and how do they define its application fit in power-supply designs?
The EEE-HA0J101WR is rated at 100 µF capacitance and 6.3 V working voltage, making it appropriate for bulk decoupling on 3.3 V and 5 V output rails where the voltage never exceeds 6.3 V. A 100 µF capacitor at these voltages can absorb transient load steps of several hundred milliamps, reducing rail ripple below 50 mV in typical switch-mode converter designs operating at 100 kHz to 500 kHz switching frequency.
How does the 105 °C temperature rating of the EEE-HA0J101WR benefit designs installed in enclosures with limited airflow?
Aluminum electrolytic capacitors age primarily through electrolyte evaporation, which accelerates sharply above 85 °C. By rating the HA series to 105 °C, Panasonic allows the capacitor to operate inside fanless enclosures or near power transistors where local ambient may reach 85–95 °C, while still achieving the rated 2,000-hour life at maximum temperature. At 85 °C actual operating temperature the life extends to approximately 8,000 hours per the Arrhenius doubling rule.
For an SMT production line, what package dimensions and placement requirements does the EEE-HA0J101WR impose?
The EEE-HA0J101WR is a radial-lead SMD capacitor in a cylindrical can package with a diameter of approximately 5 mm and a height of approximately 5.8 mm. The two SMD pads are spaced to match standard footprints in IPC-7351 land-pattern libraries, and the component is compatible with lead-free reflow soldering profiles peaking at 260 °C for up to 10 seconds, as required for MSL-compliant SMT assembly.
When would a designer choose the EEE-HA0J101WR over a ceramic MLCC of similar capacitance for a 5 V decoupling rail?
A 100 µF ceramic MLCC at 6.3 V in an X5R or X7R dielectric would occupy a 1210 or larger case, often costing several times more than the EEE-HA0J101WR. The aluminum electrolytic is preferred when board cost is a primary constraint and the switching frequency is below 500 kHz, where its higher ESR — typically 0.5 to 2 ohms at 100 kHz — is still acceptable. The ceramic alternative is preferred only when ripple-current density or board height is severely limited.
