Key Features
- 100 µF capacitance at 35 V rated voltage in a compact SMD package for high-density power supply decoupling and bulk energy storage
- Panasonic HA series low-impedance design provides reduced ESR for improved ripple current handling in switching power supply output stages
- Surface-mount aluminum electrolytic construction enables automated pick-and-place reflow assembly, reducing board assembly time versus radial through-hole counterparts
Applications
The EEE-HAV101UAP is commonly used as an output bulk capacitor in DC-DC converter and voltage regulator circuits operating up to 35 V, where its 100 µF capacitance smooths switching ripple and supports load-transient response. It is also deployed in power-line filtering stages of industrial motor drives, LED driver modules, and set-top box power supplies that require SMD form-factor decoupling. Automotive accessory modules and consumer electronics that consolidate all passive components in reflow-compatible SMD packages also benefit from this part.

Frequently Asked Questions
What are the key electrical ratings of EEE-HAV101UAP, and which power rail voltages can it support?
The EEE-HAV101UAP is rated at 100 µF capacitance and 35 V maximum working voltage. It is suitable for bulk decoupling on 5 V, 12 V, 15 V, 24 V, and lower-voltage rails up to 35 V. Designers should apply a voltage derating of 80% in practice, limiting operating voltage to approximately 28 V for maximum long-term reliability in continuous operation.
Why is low ESR important in a bulk capacitor like EEE-HAV101UAP for switching power supply designs?
Equivalent Series Resistance (ESR) determines how much ripple voltage appears across the capacitor when switching current (at frequencies from tens of kHz to several hundred kHz) flows through it. A low-ESR 100 µF capacitor in Panasonic's HA series limits output voltage ripple and reduces internal heat generation, which extends capacitor lifetime — typically expressed as thousands of hours at 105°C in high-grade SMD electrolytic capacitors.
How does the SMD package of EEE-HAV101UAP compare to radial through-hole 100 µF 35 V alternatives in terms of board footprint?
An SMD aluminum electrolytic like the EEE-HAV101UAP mounts flush to the PCB surface without requiring drilled holes, which frees the underside of the board for routing or other components. SMD mounting also allows the capacitor to be placed closer to the switching IC's output pin, reducing parasitic inductance in the current loop — a measurable improvement in EMI performance compared to a tall radial through-hole 100 µF 35 V capacitor mounted at distance.
What Panasonic capacitor series does EEE-HAV101UAP belong to, and what is the typical temperature rating?
The EEE-HAV101UAP belongs to Panasonic's HA series of SMD aluminum electrolytic capacitors, which are rated for operation up to 105°C maximum category temperature. The HA series is characterized by low impedance over a wide frequency range, making it suitable for high-frequency switching circuits where standard 85°C aluminum electrolytics would suffer higher ESR and shorter lifetime under thermal stress.
