Key Features
- AEC-Q200 automotive-grade rating with 2000-hour endurance at 125°C for reliable operation in engine bay and powertrain environments
- Low ESR of 0.075 Ω combined with 1300 mA ripple current capacity supports high-frequency switching power supply decoupling
- High 4700 µF capacitance in a compact 18 x 16.5 mm SMD package enables bulk energy storage without through-hole assembly
Applications
The EEE-TK1A472AM is used in automotive ECU power stages, DC-DC converters, and motor drive circuits where a 4700 µF, 10 V bulk capacitor with low 0.075 Ω ESR is required to stabilize voltage rails and absorb load transients. It is also suited to industrial SMPS output filtering and ADAS subsystem power conditioning that demand 2000-hour, 125°C operational durability.

Frequently Asked Questions
What ripple current and ESR does the EEE-TK1A472AM support in a switching supply output stage?
The EEE-TK1A472AM is rated for 1300 mA ripple current and an ESR of 0.075 Ω. These characteristics make it effective at filtering switching-frequency ripple in buck or boost converters operating at tens to hundreds of kHz, keeping output voltage deviation low even under dynamic load changes.
How long does the EEE-TK1A472AM last at maximum rated temperature, and why does that matter for automotive designs?
Panasonic rates this capacitor for 2000 hours of operation at 125°C. For automotive applications near engine management units or powertrain controllers, this endurance is critical because ambient temperatures can reach 105°C to 125°C continuously, and a shorter-life component would fail prematurely and trigger warranty issues.
Can the EEE-TK1A472AM replace through-hole electrolytic capacitors of the same value in a board redesign?
Yes, the 18 x 16.5 mm SMD footprint allows the EEE-TK1A472AM to replace 4700 µF, 10 V through-hole capacitors in a board respin targeting SMT-only assembly. Designers should verify the land pattern accommodates the 18 mm diameter and confirm the 0.075 Ω ESR and 1300 mA ripple rating meet the original design's thermal and filtering requirements.
