• High-temperature endurance: Endurance specified to 5000 hours at +105 °C (per UPM series specifications), supporting long-term operation in elevated-temperature environments.
• Low impedance & ripple handling: Specified impedance of 89 mΩ and ripple-current ratings of 672 mA at 120 Hz and 1.12 A at 200 kHz for effective smoothing and noise suppression under AC ripple loading.
• AEC-Q200 qualified: Meets AEC-Q200 qualification, indicating suitability for environments requiring component-level automotive reliability.
• Radial-lead package: φ18 × 20 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB implementations.
• Wide operating range: Rated for -55 °C to +105 °C operation and specified leakage and loss characteristics per the UPM series datasheet.
• Packaging options: Available in bulk (no terminal forming) or bag packing to suit production and assembly preferences.
• RoHS compliant: Conforms to RoHS requirements for regulatory compliance in applicable regions.

Typical Applications

• Automotive power electronics: Use for smoothing, decoupling and energy storage where AEC-Q200 qualification and elevated temperature endurance are required.
• Power-supply filtering: Effective for bulk filtering and ripple suppression in high-voltage DC rails thanks to its 80 V rating and low impedance.
• DC-link and motor drive support: Provides energy buffering and ripple current handling for DC-link circuits and motor drive power stages.
• Control modules and embedded systems: Suited for board-level power stabilization in modules that must withstand high ambient temperatures and continuous loading.

Unique Advantages

• High-voltage capability: 80 V rating enables use in higher-voltage rails where lower-voltage electrolytics are not suitable.
• Proven long-term reliability: 5000-hour load-life rating at 105 °C demonstrates durability for sustained high-temperature operation.
• Measured low impedance: 89 mΩ impedance specification supports lower ripple voltage and improved transient performance in power circuits.
• Frequency-versatile ripple performance: Ripple-current specifications at 120 Hz and 200 kHz provide design confidence across a range of switching and line-frequency environments.
• Automotive-grade qualification: AEC-Q200 status aligns the part with automotive reliability programs and qualifying processes.
• Compact radial form factor: φ18 × 20 mm can and 7.5 mm lead spacing allow a balance of capacitance density and through-hole mounting convenience.
