Key Features
- 330 µF capacitance at 6.3 V with ±20% tolerance in a compact 8×6.2 mm SMD footprint optimized for high-density automotive PCBs
- AEC-Q200 automotive grade qualification ensures reliability across harsh temperature cycling and vibration conditions from -40°C to +105°C
- 2000-hour rated lifetime at 105°C with 300 mA allowable ripple current, enabling use in demanding DC-DC converter output filter designs
- Surface-mount tape-and-reel packaging supports high-volume automated pick-and-place assembly for automotive electronic control units
Applications
EEE-FK0J331P is designed for automotive ECU power supply filtering, infotainment system DC-DC converter output stages, and ADAS sensor module bulk decoupling where 330 µF at 6.3 V is required in a compact SMD package. Its 105°C, 2000-hour AEC-Q200 rating makes it equally suitable for under-hood applications such as engine management units and electric power steering controllers. Industrial designers also use this capacitor in compact switching regulators and motor-drive filter stages that need reliable SMD aluminum electrolytic performance at low voltages.

Frequently Asked Questions
What are the key electrical ratings of the EEE-FK0J331P and how do they affect DC-DC converter output filter design?
EEE-FK0J331P is rated at 330 µF capacitance and 6.3 V working voltage with ±20% tolerance, and it handles up to 300 mA of ripple current. For a 5 V or below DC-DC converter output stage, these ratings provide ample bulk capacitance to reduce output voltage ripple to well below 50 mV while staying within the 6.3 V voltage rating with sufficient margin.
Why is EEE-FK0J331P a suitable choice for automotive ECU designs operating in under-hood environments?
EEE-FK0J331P carries AEC-Q200 automotive qualification and is rated for a 2000-hour lifetime at 105°C, covering the sustained high-temperature environment typical of under-hood ECUs. Its operating temperature range of -40°C to +105°C and SMD construction reduce mechanical stress from thermal cycling, making it reliable for engine management units and electric power steering controllers where capacitor failure is safety-critical.
How does the 8×6.2 mm SMD can size of EEE-FK0J331P compare to alternative 330 µF aluminum electrolytics at 6.3 V?
The 8×6.2 mm footprint of EEE-FK0J331P is a standard compact SMD can size that occupies approximately 50 mm² of PCB real estate, smaller than many through-hole 330 µF 6.3 V alternatives which require 8 mm diameter radial cans with 3.5 mm lead spacing. This makes it well-suited for dense PCB layouts in automotive infotainment or ADAS modules where board space is limited to under 100 cm².
Can EEE-FK0J331P be used in industrial switching regulators, and what ripple current ceiling must designers respect?
Yes, EEE-FK0J331P can be used in industrial 5 V rail DC-DC switching regulators as an output bulk capacitor. Designers must keep the RMS ripple current at or below 300 mA to stay within the capacitor's rated limit, and should derate to around 240 mA in continuous operation at 85°C for extended service life beyond the specified 2000 hours.
