Key Features
- 150 µF capacitance at 35 V DC rating handles bulk energy storage and voltage ripple suppression in switch-mode power supply output stages
- 105°C maximum operating temperature rating ensures reliable performance in high-ambient environments such as automotive and industrial power modules
- Surface-mount 8 mm × 10.2 mm aluminum electrolytic case enables automated SMT assembly without through-hole drilling
- Ultra-low leakage current of 0.0525 mA minimizes standby power dissipation in battery-powered or energy-harvesting circuit designs
Applications
The EEEFK1V151GP is primarily used as an output bulk capacitor in DC/DC converters and AC/DC power supplies operating at 12 V to 24 V output rails, where 150 µF of capacitance smooths switching ripple and maintains output voltage during load transients. Its 35 V rating provides a safety margin on 24 V bus designs per standard 1.5x derating practices recommended by IPC-SM-785. Industrial automation controllers, servo drives, and LED driver power stages rely on this capacitor's 105°C rating to survive elevated ambient temperatures without premature electrolyte dry-out.

Frequently Asked Questions
What voltage and capacitance ratings does EEEFK1V151GP carry, and what derating guideline applies in 24 V bus designs?
The EEEFK1V151GP is rated at 150 µF and 35 V DC working voltage. For a 24 V output bus, this provides a 1.46x voltage derating factor, which falls just below the commonly recommended 1.5x guideline. Design teams should verify actual peak voltage spikes on the rail; if spikes exceed 28 V (80% of rated), selecting the next voltage grade at 50 V is advisable to maintain a long capacitor lifetime above 5,000 hours at 105°C.
How does the 105°C temperature rating of EEEFK1V151GP affect expected service life in a power supply running at 85°C ambient?
Aluminum electrolytic capacitor life roughly doubles for every 10°C reduction in operating temperature below the rated maximum of 105°C. Operating EEEFK1V151GP at 85°C ambient adds approximately 20°C of margin, which can extend the rated lifespan (typically 2,000 to 5,000 hours at 105°C) to between 8,000 and 20,000 hours at 85°C. This makes it suitable for industrial equipment targeting 10-year field lifetimes when core temperature stays below 85°C.
What physical dimensions does EEEFK1V151GP have, and what pad layout does the PCB footprint require?
EEEFK1V151GP measures 8 mm in diameter and 10.2 mm in height, placing it in the standard D-size aluminum electrolytic SMD case. The recommended PCB footprint uses two pads spaced 3.5 mm apart center-to-center, with pad dimensions of approximately 2.3 mm × 3.0 mm each. A keep-out zone of 8.5 mm diameter around the body center prevents interference with adjacent components during reflow soldering.
With a 21-week factory lead time, how should procurement teams source EEEFK1V151GP for a production launch in 5 months?
A 21-week (approximately 5.25-month) lead time means orders placed today would arrive after a standard 5-month production target. Procurement teams should issue purchase orders immediately or source from stocking distributors carrying buffer inventory. Additionally, qualifying a second-source 150 µF, 35 V, 105°C SMD aluminum capacitor from vendors such as Nichicon or Rubycon with a 4-8 week lead time provides a reliable fallback that avoids halting the production line.
