Key Features
- 220 µF capacitance at 50 V with 0.11 mA leakage current in a compact 10 mm diameter, 10.2 mm height radial can for space-efficient power filtering
- Wet aluminum electrolytic construction delivers high capacitance-to-volume ratio suitable for bulk energy storage in switching power supplies
- REACH-compliant and lead-free (RoHS) with radial termination for through-hole PCB assembly in industrial and consumer electronics
Applications
The EEE1HA221UAP is suited for output bulk filtering in 50 V switching power supplies, DC-DC converters, and motor drive inverters where 220 µF of low-leakage capacitance smooths output ripple and stabilizes voltage rails. Its compact 10 mm diameter radial form factor also makes it practical for audio amplifier power supply stages and industrial control boards requiring reliable electrolytic bulk storage.

Frequently Asked Questions
What capacitance, voltage, and leakage current specs does the EEE1HA221UAP offer?
The EEE1HA221UAP provides 220 µF of capacitance rated at 50 V with a maximum leakage current of 0.11 mA. These values make it effective for bulk output filtering in switching power supplies and DC bus stabilization where low leakage is important for energy efficiency.
What are the physical dimensions of EEE1HA221UAP and how do they affect PCB layout?
The EEE1HA221UAP measures 10 mm in diameter and 10.2 mm in height in a radial can configuration. This compact footprint fits standard through-hole PCB pad patterns for 10 mm diameter electrolytics, enabling high-capacitance 220 µF placement even in boards with tight component height restrictions of around 12 mm.
Can EEE1HA221UAP be used in 48 V bus industrial power supply designs?
Yes. With a 50 V voltage rating, the EEE1HA221UAP provides a 2 V margin above a 48 V bus, which is often sufficient for light-load conditions. However, for 48 V nominal rails with transient spikes exceeding 50 V, a higher-rated 63 V or 100 V capacitor would be recommended to ensure long-term reliability.
How does the wet aluminum electrolytic technology of EEE1HA221UAP compare to solid polymer alternatives for power filtering?
Wet aluminum electrolytics like the EEE1HA221UAP deliver higher capacitance per unit cost (220 µF at 50 V) compared to solid polymer capacitors of the same can size, but have higher ESR (typically 0.5 Ω to 2 Ω at 100 Hz) and lower ripple current ratings than polymer types, making them ideal for bulk filtering rather than high-frequency ripple suppression.
