Key Features
- 220 µF capacitance at 25 V with 20% tolerance in a compact 8x10.2 mm SMD package for power supply decoupling in space-constrained automotive PCBs
- Automotive-grade qualification with 2000-hour rated lifetime at 105°C ensures reliability in engine bay and under-hood applications per AEC-Q200 standards
- 160 mA ripple current rating supports high-frequency switching power supply filtering from 10 kHz to 100 kHz without exceeding temperature limits
Applications
The EEE-HA1E221UP is used as a bulk output capacitor in automotive DC-DC converters and ECU power stages where 25 V rails must be filtered under continuous 105°C ambient conditions for at least 2000 hours. Its 220 µF capacitance and 160 mA ripple current rating make it suitable for smoothing switching regulator outputs in dashboard electronics, ADAS sensor power supplies, and body control modules. The SMD form factor supports automated reflow assembly on high-density automotive PCBs where through-hole capacitors cannot be used.

Frequently Asked Questions
How does the EEE-HA1E221UP's 105°C 2000-hour lifetime rating translate to expected service life in a typical automotive ECU?
Rated at 105°C for 2000 hours, the EEE-HA1E221UP follows the Arrhenius rule for electrolytic capacitors: every 10°C reduction in operating temperature approximately doubles the expected service life. At a typical ECU operating temperature of 85°C, the estimated lifetime extends to approximately 8000 hours, and at 65°C it reaches around 32,000 hours, well exceeding the 15-year vehicle service life requirement for most body control applications.
Can the EEE-HA1E221UP handle the ripple current from a 100 kHz automotive buck converter output stage?
The EEE-HA1E221UP is rated for 160 mA ripple current, which is sufficient for most low-to-medium power automotive buck converters operating at 100 kHz with output loads up to 2 A. Above 160 mA ripple, the capacitor's internal ESR dissipation will cause internal heating that reduces the 2000-hour lifetime at 105°C. For higher ripple applications above 200 mA, two EEE-HA1E221UP units in parallel provide 320 mA combined ripple capacity.
What is the physical footprint of the EEE-HA1E221UP and how does it fit on a standard automotive PCB land pattern?
The EEE-HA1E221UP measures 8 mm diameter by 10.2 mm height in a vertical SMD can package. The recommended PCB land pattern uses a circular pad diameter of 8.3 mm with a keepout radius of 4.5 mm from the center, requiring approximately 70 mm² of board area per capacitor. This is compatible with standard IPC-7351 SMD aluminum electrolytic land patterns for 8 mm body components.
