Key Features
- 100 µF capacitance at 25 V rated voltage in a compact SMD footprint, delivering high energy density for surface-mount power circuits
- ±20% capacitance tolerance (EIA Class III) covers bulk energy storage applications where tight tolerance is less critical than high capacitance value
- Low ESR aluminum electrolytic construction minimizes power losses and heat rise in high-ripple switching power supply output filters
- Full reel packaging ensures consistent tape-and-reel supply for high-volume automated SMT assembly lines with predictable reel quantities
- RoHS-compliant, lead-free terminations compatible with SAC305 reflow processes and international environmental compliance standards
Applications
The EEE-HA1E101P is widely used as bulk output capacitor and power-rail decoupling in switching power supplies, DC-DC converters, and motor driver boards operating up to 25 V. Its 100 µF capacitance provides low-frequency ripple filtering on 5 V, 12 V, and 24 V power rails in industrial controllers, consumer electronics, and telecommunications equipment. The SMD form factor suits high-density PCB assemblies including notebook adapter output stages, LED driver circuits, and inverter input-stage bulk storage.

Frequently Asked Questions
What are the rated capacitance and voltage of the EEE-HA1E101P, and which power rails does it suit?
The EEE-HA1E101P is rated at 100 µF capacitance with a 25 V maximum working voltage and ±20% tolerance. It is well suited for decoupling and bulk storage on power rails from 3.3 V to 24 V, where its 100 µF value provides effective attenuation of low-frequency ripple components below 10 kHz in switching converter output stages and motor driver supply lines.
How does the SMD package of EEE-HA1E101P enable high-density board assembly compared to radial through-hole capacitors?
The SMD package of EEE-HA1E101P eliminates the need to drill through-hole vias, saving approximately 1 mm² of PCB area per capacitor and enabling reflow-oven population alongside other surface-mount components. A typical 6.3 mm diameter SMD aluminum electrolytic occupies roughly 40% less board height than an equivalent radial capacitor, allowing thinner product enclosures in notebook computers, set-top boxes, and handheld instruments where vertical clearance is under 10 mm.
What is the ESR characteristic of EEE-HA1E101P, and how does it affect ripple current handling in a DC-DC converter output filter?
The EEE-HA1E101P features a low ESR aluminum electrolytic construction that limits self-heating during ripple current operation, typically allowing continuous ripple currents of 200 mA to 400 mA at 100 kHz depending on case size and temperature. Lower ESR means less voltage drop across the capacitor at rated ripple frequency, resulting in tighter output voltage regulation and reduced thermal stress at ambient temperatures up to 85°C in standard HA-series ratings.
Is EEE-HA1E101P RoHS compliant, and does it support standard lead-free reflow assembly processes?
Yes, EEE-HA1E101P is RoHS compliant with lead-free terminations, fully compatible with SAC305 solder paste and standard lead-free reflow profiles peaking at 260°C. The capacitor body and electrolyte are formulated to withstand the thermal shock of two reflow passes, which is required for double-sided SMT PCB assembly, without degrading capacitance by more than 5% or increasing ESR beyond the rated specification.
What full reel quantity does EEE-HA1E101P ship in, and how does this affect procurement for medium-volume production runs?
EEE-HA1E101P ships in full reel format, typically containing 500 to 2000 units per reel depending on case size, which simplifies procurement planning for production runs of 500 or more PCBs per batch. Full reels eliminate the cut-tape handling penalties that add 10–15% to unit pricing, and the tape-and-reel format directly loads into automated placement machines rated for 0402 to electrolytic component sizes without manual intervention.
