Applications
The EEE-HD1C220AR is designed for automotive ECU power supply decoupling, infotainment system rail filtering, and ADAS module bulk capacitance where AEC-Q200 reliability and 105°C operation are required. Its 22µF 16V rating in a 5x5.8mm SMD package suits compact automotive power conversion circuits operating from 12V vehicle battery rails stepped down to logic-level voltages. Industrial motor drives and charging station power modules also use this capacitor for output ripple suppression in thermally demanding enclosures.

Frequently Asked Questions
How does the EEE-HD1C220AR's 5000-hour 105°C rating support automotive ECU reliability requirements?
The EEE-HD1C220AR is rated for 5000 hours at 105°C, meeting AEC-Q200 Grade 2 automotive qualification for under-hood and ECU applications where temperature cycles regularly reach 85°C to 105°C. Its 22µF 16V capacitance and 39mA ripple current rating ensure stable power supply filtering over the vehicle's design life in powertrain and body control modules.
Which power rail filtering tasks in automotive infotainment systems suit the 22µF 16V EEE-HD1C220AR?
Post-regulator decoupling on 3.3V and 5V logic rails stepped down from a 12V vehicle bus benefits from the EEE-HD1C220AR's 22µF 16V rating, which provides adequate bulk capacitance to suppress switching transients at frequencies up to several hundred kHz. The 5x5.8mm SMD footprint fits standard 0.1-inch grid placements on automotive infotainment and cluster PCBs with tight component density.
When is the EEE-HD1C220AR a better fit than a ceramic capacitor for 22µF decoupling at 16V?
For 22µF at 16V where ceramic capacitors exhibit significant DC-bias derating — often losing 40% to 60% of rated capacitance at operating voltage — the EEE-HD1C220AR aluminum electrolytic maintains its 22µF value with only 20% tolerance across the full voltage range. This makes it a cost-effective and space-efficient choice on automotive 12V-to-5V converter output stages where stable bulk capacitance is critical.
