Key Features
- 470 µF capacitance at 63 V rated voltage with 20% tolerance for reliable automotive power storage and filtering
- Low ESR of 0.18 Ohm and 500 mA ripple current capacity enabling efficient power supply decoupling at high frequencies
- AEC-Q200-compliant automotive grade rated to 125°C for 2000 hours in demanding under-hood environments
Applications
The EEE-TK1J471AM is designed for automotive power supply filtering, DC-DC converter output smoothing, and bulk energy storage in vehicle electronic control units (ECUs) operating at up to 125°C. Its 470 µF, 63 V rating and low 0.18 Ohm ESR make it suitable for high-temperature bulk decoupling in advanced driver assistance systems (ADAS), powertrain controllers, and infotainment modules. The SMD package with tape-and-reel delivery supports automated reflow assembly on automotive-grade PCBs.

Frequently Asked Questions
What are the key electrical ratings of the EEE-TK1J471AM and what do they mean for power circuit design?
The EEE-TK1J471AM is rated at 470 µF capacitance, 63 V working voltage, 0.18 Ohm ESR, and 500 mA ripple current. These values make it suitable for bulk filtering on 12 V to 48 V automotive power rails, where the low ESR reduces heat generation and the 470 µF capacitance handles transient load demands in ECU and power converter designs.
How does the 125°C, 2000-hour lifetime rating make EEE-TK1J471AM suitable for automotive applications?
The EEE-TK1J471AM is rated for 2000 hours at 125°C, meeting the thermal endurance requirements for under-hood automotive environments where temperatures regularly exceed 85°C. Panasonic's TK series automotive electrolytic capacitors are designed to comply with AEC-Q200 standards, ensuring long-term reliability in powertrain controllers, ADAS units, and motor driver boards exposed to extreme heat cycles.
What physical dimensions and package type should PCB designers account for when using EEE-TK1J471AM?
The EEE-TK1J471AM uses an SMD aluminum electrolytic can measuring 16 mm diameter by 16.5 mm height. PCB designers must allocate a 16 mm footprint diameter with adequate clearance for the 16.5 mm component height, especially in systems with height restrictions such as flat automotive control modules or stacked-board assemblies.
