Key Features
- 0.22 µF capacitance at 50 V DC rating suitable for signal coupling and power supply bypass in compact SMD designs
- 4x5.8 mm SMD package enables automated reflow assembly on high-density PCBs with minimal board footprint
- Panasonic HC series reliability with long rated service life and low equivalent series resistance (ESR) for stable performance
Applications
The EEE-HC1HR22R is well suited for power supply decoupling, audio signal coupling, and bypass filtering in consumer electronics, communication equipment, and industrial control boards. Its 50 V rating and 0.22 µF capacitance support use on regulated 5 V, 12 V, and 24 V rails where polarized SMD capacitors are preferred over ceramic types for their higher capacitance density. The 4x5.8 mm footprint fits standard SMD land patterns on FR4 boards assembled by automated pick-and-place processes.

Frequently Asked Questions
What is the capacitance and voltage rating of the EEE-HC1HR22R, and where is it typically used?
The EEE-HC1HR22R has a capacitance of 0.22 µF with a voltage rating of 50 V DC. These values make it suitable for decoupling and bypass filtering on 5 V, 12 V, and 24 V power rails in consumer electronics, audio equipment, and industrial control systems where a polarized SMD aluminum electrolytic is required.
What are the physical dimensions of the EEE-HC1HR22R, and how does this affect PCB layout?
The EEE-HC1HR22R measures 4 mm in diameter and 5.8 mm in height in its SMD package. This relatively compact form factor fits standard aluminum electrolytic land patterns and is compatible with automated reflow soldering, though designers must ensure clearance of at least 5.8 mm vertical headroom on the PCB assembly.
When should the EEE-HC1HR22R be chosen over a ceramic capacitor of the same value for a 50 V bypass application?
The EEE-HC1HR22R aluminum electrolytic is preferred over 0.22 µF ceramic capacitors at 50 V when cost and body size are priorities, since high-voltage ceramic capacitors of equivalent capacitance in 0603 or 0805 packages may exhibit significant DC bias derating, reducing effective capacitance by 30% to 60% at 50 V. The aluminum electrolytic maintains its 0.22 µF rating more predictably under DC bias conditions.
