Key Features
- 100µF / 25V AEC-Q200 automotive-qualified SMD electrolytic in an 8×6.2mm can, balancing high capacitance density with compact board footprint
- 2000-hour endurance at 105°C exceeds standard consumer-grade capacitors, ensuring reliability in harsh automotive ECU and infotainment thermal environments
- 300mA ripple current rating supports efficient output filtering in automotive DC-DC converters and motor-driver power stages
- Tape-and-reel (T/R) automotive packaging enables high-speed pick-and-place assembly for large-volume vehicle electronics production lines
Applications
EEE-FK1E101AP is designed for bulk decoupling and output filtering in automotive ECUs, advanced driver-assistance system (ADAS) power rails, and infotainment module DC-DC converters where a 25V-rated 100µF SMD capacitor must endure 105°C continuous operation. Its AEC-Q200 qualification and 2000-hour endurance rating make it suitable for 12V automotive bus filtering where transient voltages require a 25V safety margin. The compact 8×6.2mm SMD form factor suits high-density automotive PCBs where component height and footprint area are tightly constrained.

Frequently Asked Questions
What are the electrical and thermal ratings of EEE-FK1E101AP for automotive power-supply design?
EEE-FK1E101AP is rated at 100µF capacitance, 25V DC working voltage, ±20% tolerance, 300mA ripple current, and a 2000-hour operational lifetime at 105°C. These specifications make it well suited for 12V automotive bus filtering and ECU output decoupling where bus transients can reach 18V and ambient temperatures near the PCB can reach 85–105°C.
How does EEE-FK1E101AP's AEC-Q200 qualification affect its suitability for under-hood automotive electronics?
AEC-Q200 qualification subjects EEE-FK1E101AP to automotive-grade stress tests including thermal shock from -40°C to +125°C, humidity, and vibration, confirming reliability in under-hood environments that standard commercial capacitors cannot guarantee. For ECU power-supply designers, this qualification eliminates the need for additional component-level validation testing, reducing qualification time by several months compared to using non-automotive-graded parts.
In which automotive sub-systems is EEE-FK1E101AP commonly specified as an output bulk capacitor?
EEE-FK1E101AP appears frequently on the output rails of synchronous buck converters in body-control modules, ADAS sensor power supplies, and automotive infotainment boards where a 100µF / 25V SMD capacitor provides bulk energy storage during load transients. The 300mA ripple current rating is sufficient for converters switching at 200kHz to 500kHz, covering most automotive-grade DC-DC modules that power MCUs, FPGAs, and sensor interfaces from a 12V or 24V vehicle bus.
How does the 8×6.2mm SMD can of EEE-FK1E101AP compare in size to a through-hole 100µF/25V equivalent for automotive PCB layouts?
At 8mm diameter and 6.2mm height, EEE-FK1E101AP occupies a footprint of roughly 50 mm² with no board-drilling requirement, compared to a typical through-hole 100µF/25V radial can that requires 2 plated holes and a footprint of 65 mm² or more. The SMD design enables co-planarity with other surface-mount components and allows reflow-only board assembly, which is standard in automotive electronics manufacturing and reduces per-board cycle time by eliminating a separate wave-solder pass.
