Key Features
- 1000 µF at 35 V with automotive-grade qualification supporting 2000-hour lifespan at 125 °C for underhood ECU power rails
- Ultra-low 0.075 Ω ESR enabling 1300 mA ripple current handling in DC-DC converters and motor-drive bulk decoupling
- SMD 18 mm × 16.5 mm can format in tape-and-reel packaging for automated SMT assembly on automotive PCB production lines
Applications
The EEE-TK1V102AM is optimized for bulk decoupling and energy storage on 24 V and 28 V automotive ECU power rails, where high ripple currents from switching regulators require low-ESR capacitors rated to 125 °C. Its 2000-hour endurance at full temperature suits engine-bay control modules, electric power steering controllers, and 48 V mild-hybrid inverter boards. The tape-and-reel SMD format integrates into high-throughput automotive PCB assembly lines without manual insertion.

Frequently Asked Questions
What ESR and ripple current capability does the EEE-TK1V102AM offer for automotive DC-DC converter output filtering?
The EEE-TK1V102AM has an ESR of 0.075 Ω and a rated ripple current of 1300 mA at 125 °C. In a 35 V automotive DC-DC converter switching at 100 kHz, this ESR produces only 97.5 mV of ripple voltage across the capacitor at full 1300 mA ripple, well within the 200 mV ripple budget of most automotive microcontroller power rails.
How does the 125 °C, 2000-hour endurance rating of the EEE-TK1V102AM compare to standard commercial-grade capacitors for ECU designs?
A standard commercial 85 °C-rated 1000 µF capacitor typically offers 1000-hour endurance at maximum temperature, whereas the EEE-TK1V102AM doubles that to 2000 hours at 125 °C. Using the Arrhenius rule-of-thumb (life doubles for every 10 °C reduction), the EEE-TK1V102AM at a 105 °C operating point offers approximately 8000 hours—meeting automotive PPAP requirements for a 10-year vehicle service life under intermittent underhood duty cycles.
What SMD footprint and can dimensions does the EEE-TK1V102AM require on an automotive PCB?
The EEE-TK1V102AM uses an 18 mm diameter × 16.5 mm height SMD can, requiring a PCB footprint pad pattern of approximately 18.6 mm diameter with a 2-pad configuration and a minimum courtyard clearance of 0.5 mm. The total component height of 16.5 mm must be verified against enclosure Z-height constraints in automotive ECU housings, which typically allow components up to 18 mm tall on the bottom PCB side.
For a 48 V mild-hybrid inverter board, how many EEE-TK1V102AM capacitors are typically needed for the main DC bus decoupling?
A 48 V mild-hybrid inverter operating at 10 kW with a 10% voltage ripple limit needs approximately 2780 µF of bus capacitance (C = P / (V × ΔV × f), at 100 kHz switching). Three EEE-TK1V102AM units in parallel provide 3000 µF of 35 V-rated capacitance—note that for a 48 V bus, capacitors rated at 63 V should be used, so this part is more appropriate for the 24 V or 28 V sub-rails within the same system.
