Key Features
- 47 µF capacitance at 16 V rating with ±20% tolerance in a compact 6.3 mm × 5.8 mm SMD package, enabling bulk decoupling in space-constrained automotive PCBs
- 105°C maximum operating temperature and 2000-hour rated lifetime qualifying it for automotive under-hood and harsh industrial thermal environments
- 240 mA ripple current capability and AEC-Q200 automotive qualification ensure reliable bulk filtering in ECU power supply and DC-DC converter output stages
Applications
The EEE-FK1C470AP is designed for bulk capacitance and output filtering in automotive ECUs, ADAS processors, and in-vehicle infotainment power supplies where 16 V rail decoupling at elevated temperatures is required. Its 2000-hour lifetime at 105°C and AEC-Q200 compliance also make it suitable for industrial motor controllers, LED driver output filters, and DC-DC converter outputs in harsh-environment embedded systems.

Frequently Asked Questions
What ripple current can the EEE-FK1C470AP handle continuously and why does this matter for DC-DC converter designs?
The EEE-FK1C470AP is rated for 240 mA maximum ripple current at its full 105°C operating temperature. In DC-DC converter output filters, the capacitor must absorb the inductor ripple current without excessive internal heating that would degrade its 2000-hour lifetime. Selecting a capacitor with adequate ripple current rating prevents premature dry-out of the electrolyte and maintains the 47 µF capacitance over the product lifetime.
Is EEE-FK1C470AP suitable for automotive ECU designs, and which qualification standard does it meet?
Yes, the EEE-FK1C470AP is an AEC-Q200 automotive-qualified component, meeting the stress test requirements for passive components used in automotive applications. This qualification covers temperature cycling, damp heat, high-temperature storage, and life test at 105°C, ensuring reliability in engine control units, body control modules, and ADAS ECUs where capacitors must survive vehicle lifetimes of 10 or more years.
How does the 6.3 mm × 5.8 mm SMD package of EEE-FK1C470AP affect PCB layout compared to through-hole electrolytic caps?
The 6.3 mm diameter × 5.8 mm height SMD form factor of EEE-FK1C470AP eliminates the need for through-holes in the PCB, allowing placement on the component side only and enabling bottom-side component area to be used for other components. The SMD footprint also supports automated reflow soldering, whereas through-hole electrolytic capacitors of equivalent 47 µF 16 V rating require wave soldering or manual insertion.
What is the rated operating lifetime of EEE-FK1C470AP and how does temperature affect its longevity?
The EEE-FK1C470AP is rated for 2000 hours at its maximum 105°C operating temperature. Applying the standard electrolytic capacitor lifetime rule-of-thumb (lifetime doubles for every 10°C reduction in temperature), operating it at 85°C yields approximately 8000 hours, and at 65°C approximately 32000 hours. This derating characteristic allows designers to predict service life for specific thermal environments in automotive or industrial 12 V or 16 V rail applications.
