Designed and tested for demanding environments, this AEC-Q200 qualified, RoHS-compliant device targets applications that require sustained performance at elevated temperatures and long operating life.

Key Features

• Conductive polymer chemistry — Solid electrolytic construction for stable electrical performance and enhanced ripple-current capability.
• Rated capacitance and tolerance — 120 µF with ±20% tolerance at 120 Hz, 20°C.
• Rated voltage — 25 V DC rating for mid-voltage rail applications.
• Low ESR — 29 mΩ measured at 100 kHz, enabling lower losses and improved transient response.
• High ripple current — 395 mA at 120 Hz and 790 mA at 100 kHz to support power conversion and decoupling duties.
• Extended high-temperature endurance — Lifetime of 3000 hours at 125°C, suitable for prolonged operation in elevated-temperature environments.
• Wide operating temperature range — −55°C to +125°C for broad deployment across harsh operating conditions.
• SMD can package, reflow compatible — Surface-mount can with lead-free reflow compatibility (260°C peak) for modern assembly processes.
• Automotive-grade qualification — AEC-Q200 qualified for designs requiring component-level automotive screening.
• RoHS compliant — Meets EU RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power electronics — Engine control modules, power distribution and in-vehicle electronics where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC converters and voltage regulation — Output smoothing and decoupling on mid-voltage rails leveraging low ESR and high ripple current capability.
• Industrial power modules — Power supplies and converters operating in elevated ambient temperatures that demand long-life capacitors.

Unique Advantages

• High-temperature longevity: 3000 hours at 125°C provides predictable lifetime performance for thermally demanding designs.
• Reduced loss and heat generation: 29 mΩ ESR at 100 kHz lowers power dissipation under ripple current stress.
