Key Features
- 100 µF capacitance at 25 V DC rating in a compact SMD D8 package (6.3 mm diameter × 7.7 mm height), optimized for high-density PCB layouts in consumer and industrial power supplies
- 1000-hour rated lifetime at 105°C operating temperature, extending mean time between failure in applications with elevated ambient temperatures such as LED drivers and motor controllers
- Low ESR HA-series design reduces ripple voltage on 5 V and 12 V DC rails, improving transient load response in switch-mode power supply output filter stages
Applications
The EEE-HA1E101XP is used as an output filter capacitor in switch-mode power supplies, DC-DC converters, and LED driver circuits where 100 µF bulk capacitance at 25 V and low ESR are needed in a small SMD footprint. Its 105°C, 1000-hour rating makes it suitable for automotive-adjacent industrial equipment, set-top boxes, and LCD monitor power boards operating in high-ambient-temperature environments. The 6.3 mm × 7.7 mm D8 SMD package fits standard land patterns on 4-layer PCBs used in compact power module designs.

Frequently Asked Questions
What capacitance, voltage rating, and physical size does the EEE-HA1E101XP provide?
The EEE-HA1E101XP provides 100 µF of capacitance at a 25 V DC rated voltage in a surface-mount D8 package measuring 6.3 mm in diameter by 7.7 mm in height. This combination delivers adequate bulk capacitance for 12 V to 25 V rail decoupling while occupying only 31 mm² of PCB footprint area.
For an LED driver circuit operating at 45°C ambient, how long can the EEE-HA1E101XP be expected to last?
Rated for 1000 hours at 105°C, the EEE-HA1E101XP lifespan roughly doubles for every 10°C reduction in operating temperature per Arrhenius degradation law. At 45°C case temperature (60°C below the 105°C rating, i.e. 6 halving steps), the projected lifetime extends to 1000 × 2^6 = 64,000 hours — over 7 years of continuous operation in a well-cooled LED driver.
How does the low-ESR HA-series design of EEE-HA1E101XP improve output ripple in a 5 V SMPS?
In a 5 V / 3 A switch-mode power supply switching at 200 kHz, a low-ESR capacitor like the HA-series 100 µF unit limits output ripple to approximately 15 mV peak-to-peak compared to 50-80 mV with a standard aluminum electrolytic of the same capacitance. The reduced ESR also lowers self-heating by cutting I²·ESR dissipation during ripple current flow, extending capacitor life beyond the rated 1000 hours.
Can the EEE-HA1E101XP replace a through-hole 100 µF 25 V capacitor in a board redesign, and what must change on the PCB?
Yes, the EEE-HA1E101XP can replace a through-hole 100 µF 25 V capacitor electrically, but the PCB layout must change from through-hole pads to SMD land pads sized for the 6.3 mm D8 footprint per Panasonic's recommended pad pattern (typically 6.6 mm diameter solder ring). The SMD version is 7.7 mm tall versus a typical 11 mm for through-hole equivalents, saving 3 mm of vertical clearance.
