Applications
EEE-HA1V220WR is used in automotive electronic control units, ADAS modules, and infotainment systems requiring reliable bulk capacitance at 35 V rails with compact SMD footprints. Its 105°C rating makes it suitable for under-hood installations subject to high ambient temperatures from engine heat. The 22 µF capacitance provides effective output filtering for DC-DC converters and voltage regulator modules operating at switching frequencies above 100 kHz.

Frequently Asked Questions
What voltage and capacitance ratings does EEE-HA1V220WR offer for automotive power filtering?
EEE-HA1V220WR provides 22 µF capacitance at a 35 V working voltage with 20% tolerance in a 5 x 5.4 mm SMD package. These ratings make it suitable for filtering 24 V or lower bus voltages in automotive ECU power stages, where reliable capacitance under vibration and temperature extremes is critical for system stability.
How long does EEE-HA1V220WR maintain its rated performance in elevated-temperature automotive environments?
EEE-HA1V220WR is rated for 1000 hours at 105°C, which meets the base-line automotive lifetime requirement for under-dash and cabin electronics. At lower operating temperatures such as 85°C, electrolytic capacitor lifetime typically extends by a factor of 4 or more, so the component can exceed 4000 hours of service life in moderate thermal environments.
When would a designer choose EEE-HA1V220WR over a ceramic capacitor for a 35 V automotive rail?
EEE-HA1V220WR is preferred over ceramic capacitors when designs require high 22 µF capacitance at 35 V, where multilayer ceramic alternatives exhibit significant DC bias derating—often losing 50% or more of rated capacitance at full voltage. The aluminum electrolytic maintains stable capacitance near its rated 22 µF across the 35 V operating range without the voltage-dependent loss common in X5R or X7R ceramics.
