Applications
The EEE-1CA471UAP is designed for automotive electronic control units (ECUs), ADAS modules, and infotainment systems requiring reliable bulk capacitance and ripple current handling in a compact SMD package. Its 470 µF capacitance and 350 mA ripple current rating suit output filtering stages in automotive DC-DC converters and LDO regulators operating at up to 16 V. The 85°C / 1000 h automotive rating ensures long service life in under-hood and cabin electronics subject to elevated temperature and vibration.

Frequently Asked Questions
What capacitance, voltage rating, and ripple current can the EEE-1CA471UAP handle in automotive DC-DC converter designs?
The EEE-1CA471UAP provides 470 µF of capacitance rated at 16 V with a ripple current capability of 350 mA. These parameters make it well-suited for output filtering in automotive step-down DC-DC converters supplying 12 V or lower rails in ECUs and ADAS modules, where bulk charge storage and AC ripple absorption are required simultaneously.
How does the 85°C / 1000 h lifetime rating of the EEE-1CA471UAP compare to standard commercial electrolytic capacitors for automotive use?
Standard commercial aluminum electrolytic capacitors are typically rated at 85°C for 1000 h to 2000 h, while automotive-qualified versions like the EEE-1CA471UAP must meet additional AEC-Q200 qualification tests covering thermal shock, humidity, and vibration. The 1000 h rating at 85°C translates to a longer effective service life at lower ambient temperatures typical of cabin electronics, following Arrhenius lifetime calculations where every 10°C reduction roughly doubles capacitor life.
What PCB footprint does the 8 × 10.2 mm SMD package of the EEE-1CA471UAP require, and how does it compare to through-hole 470 µF alternatives?
The EEE-1CA471UAP's 8 mm diameter × 10.2 mm height SMD package requires a circular land pattern approximately 8 mm in diameter, enabling fully automated reflow assembly. Equivalent 470 µF through-hole capacitors typically use an 8 mm body with 3.5 mm lead spacing, which requires wave soldering or hand soldering and increases PCB height by several millimeters — making the SMD variant preferable in low-profile automotive PCB assemblies.
Can the EEE-1CA471UAP be used in non-automotive consumer electronics applications, and what trade-offs exist compared to standard-grade alternatives?
Yes, the EEE-1CA471UAP can be used in consumer electronics wherever 470 µF at 16 V in an 8 × 10.2 mm SMD package is required. The automotive qualification adds cost compared to standard commercial capacitors, but offers a more conservative 85°C / 1000 h specification that translates to improved reliability in consumer power supplies, UPS units, and industrial converters operating at sustained elevated ambient temperatures.
