Applications
The EEE-HA1J470P is used in automotive power supply modules, DC-DC converters, and ECU power rails where 47 µF bulk capacitance at 63 V is required for energy storage, input filtering, and transient suppression. Its 105°C/2000-hour rating ensures long service life in underhood and cabin automotive environments subject to elevated temperature cycling. The SMD radial form factor supports high-density PCB assembly in infotainment systems, ADAS modules, and body control units.

Frequently Asked Questions
What voltage and capacitance ratings does EEE-HA1J470P provide for automotive power supply filtering?
The EEE-HA1J470P offers 47 µF capacitance at a 63 V DC rating, making it suitable for filtering and energy storage on 12 V to 48 V automotive bus rails with typical operating voltages well within the 63 V maximum. The 20% tolerance allows for capacitance values between 37.6 µF and 56.4 µF across production lots.
How does the 2000-hour rated lifetime at 105°C affect reliability calculations for automotive ECU designs?
The 2000-hour lifetime at 105°C is the rated end-of-life point per JIS C 5101 standards. In practice, aluminum electrolytic capacitor lifetime roughly doubles for every 10°C decrease in operating temperature, so at 85°C the EEE-HA1J470P would be expected to last approximately 8000 hours — well exceeding the typical 5-year automotive design life for non-safety-critical cabin electronics.
What ripple current can EEE-HA1J470P handle and how does this limit its use in high-frequency switching converters?
The EEE-HA1J470P is rated for 50 mA maximum ripple current at 105°C. This is relatively modest compared to lower-ESR polymer or film capacitors rated for several hundred milliamps. In high-frequency buck converters operating above 100 kHz with significant output ripple, exceeding this 50 mA limit would accelerate electrolyte degradation, so thermal derating or paralleling multiple capacitors is recommended for higher-ripple applications.
