Key Features
- 100 µF capacitance at 35 V rating provides substantial bulk energy storage for input filtering and output decoupling in 24 V or 28 V DC rail power electronics
- SMD surface-mount construction in full tape-and-reel (T/R) packaging enables automated pick-and-place assembly and eliminates manual through-hole insertion on production lines
- Panasonic HA series construction balances low ESR, high ripple current capability, and competitive cost for general-purpose industrial and consumer power supply designs
Applications
The EEE-HA1V101UP is suited for input and output bulk capacitance in industrial switching power supplies, DC-DC converter output filters, and motor driver boards operating from 24 V or 28 V DC rails. Its 100 µF 35 V rating also makes it a standard choice for audio amplifier power supply decoupling, LED driver bulk storage, and point-of-load converter output filters in consumer and industrial electronics.

Frequently Asked Questions
Why select 35 V rated EEE-HA1V101UP for a 24 V rail instead of a 25 V-rated capacitor?
Electrolytic capacitor reliability guidelines recommend selecting a voltage rating at least 1.5× to 2× the nominal operating voltage, so a 24 V rail should use a capacitor rated at 35 V or higher. The EEE-HA1V101UP's 35 V rating provides approximately 1.46× derating margin on a 24 V bus, accommodating voltage spikes and transients of several volts above nominal without stressing the dielectric or reducing the 100 µF capacitor's operational lifetime.
What does the ±20% capacitance tolerance of EEE-HA1V101UP mean for output filter design calculations?
A ±20% tolerance means the actual capacitance of EEE-HA1V101UP may range from 80 µF to 120 µF at the specified 100 µF nominal value. Filter cutoff frequency calculations must account for this variation: at 80 µF the corner frequency shifts about 12% higher than the nominal design point, potentially allowing more high-frequency ripple through. Engineers should verify the filter meets output ripple voltage specifications across the full 80–120 µF range.
How does the SMD format of EEE-HA1V101UP compare to through-hole aluminum electrolytics for high-volume production?
The SMD EEE-HA1V101UP in tape-and-reel format can be placed by standard pick-and-place equipment at throughputs of thousands of placements per hour, and reflow-soldered in a single pass with other SMD components. Through-hole 100 µF 35 V capacitors require a separate wave solder or manual insertion step, adding 5 to 15 seconds per board in assembly time. For high-volume runs of 10,000+ boards, the SMD format significantly reduces total assembly cost.
In audio power amplifier supplies, what role does EEE-HA1V101UP's 100 µF capacitance play?
In class-D or class-AB audio amplifier power supplies, 100 µF bulk capacitors like EEE-HA1V101UP reduce low-frequency supply impedance to prevent bass-frequency modulation of the supply rail. Each 100 µF capacitor on a 35 V rail contributes approximately 1 mΩ of impedance at 1 kHz (ignoring ESR), helping maintain a stiff supply that prevents audible intermodulation distortion when high-current output bursts draw from the supply during dynamic audio peaks.
