Frequently Asked Questions
How does EEE-TK1E222AM's 125°C rating and 2000-hour lifetime support automotive under-hood applications?
Rated for 2000 hours at 125°C, EEE-TK1E222AM meets AEC-Q200 automotive qualification requirements for under-hood environments, ensuring reliable operation of 2200 µF 25 V bulk capacitors near engine control units and power stages exposed to high ambient temperatures.
What ESR and ripple current specifications make EEE-TK1E222AM suitable for switching regulators?
EEE-TK1E222AM features 0.075 Ω ESR and a 1300 mA ripple current rating, allowing it to handle significant switching converter ripple at 2200 µF without excessive self-heating, making it ideal for 25 V DC-DC converter output stages in automotive ECU designs.
Which automotive subsystems most commonly use EEE-TK1E222AM as a bulk decoupling capacitor?
ADAS processing boards, infotainment amplifier power supplies, and body control module voltage regulators that require 2200 µF of bulk capacitance on a 25 V rail with 125°C thermal margin and low ESR are primary applications for EEE-TK1E222AM.
How does the 18 x 16.5 mm SMD footprint of EEE-TK1E222AM affect PCB layout in space-constrained automotive modules?
At 18 mm diameter and 16.5 mm height in a surface-mount can format, EEE-TK1E222AM can be placed by automated equipment, but the 18 mm body diameter must be accounted for in PCB clearance zones; designers typically place it on the bottom side of automotive ECU boards to preserve top-side component density.
