UPM1V681MHD

The UPM1V681MHD is a radial-lead aluminum electrolytic capacitor engineered for low impedance and high reliability. It delivers 680 µF at 35 V in a compact φ12.5 × 25 mm can and is offered in bulk or bag packing for production use.

Designed with a wide operating temperature range (−55°C to +105°C) and a 5000‑hour endurance at 105°C, the UPM1V681MHD is targeted for demanding applications that require robust power filtering under elevated temperature and continuous load conditions.

Key Features

• Capacitance and Voltage: 680 µF rated capacitance at 35 V to support bulk energy storage and power rail smoothing.
• Low Impedance: 36 mΩ impedance for improved transient response and reduced voltage ripple in power lines.
• High Ripple Capability: 958.8 mA ripple current at 120 Hz and 1.41 A at 200 kHz for reliable performance across low and high frequency ripple environments.
• Long Endurance: Rated life of 5000 hours at +105°C to meet extended operating-time requirements.
• Wide Temperature Range: Operates from −55°C to +105°C for use in thermally challenging environments.
• Polarized Radial Lead Package: Radial-lead can with 5 mm lead spacing and overall size φ12.5 × 25 mm for through-hole assemblies.
• Electrical Loss: tanδ 0.12 measured at 20°C, 120 Hz, supporting predictable ESR/impedance behavior.
• Standards and Compliance: AEC‑Q200 qualified and RoHS compliant, indicating suitability for regulated and automotive applications.

Typical Applications

• Automotive power electronics: Bulk energy storage and power-rail filtering in automotive ECUs and power modules where AEC‑Q200 qualification and high-temperature endurance are required.
• In-vehicle power supplies: Smoothing and decoupling for DC/DC converters and voltage regulators benefitting from the 35 V rating and low impedance.
• Body and infotainment electronics: Local energy reservoir and ripple suppression in modules operating across −55°C to +105°C.

Unique Advantages

• Reliable high-temperature performance: 5000-hour endurance at 105°C provides predictable lifetime behavior in hot environments.
• High ripple handling: Dual-frequency ripple ratings (958.8 mA at 120 Hz, 1.41 A at 200 kHz) support mixed-frequency power systems.
• Low impedance for stable rails: 36 mΩ impedance helps minimize voltage drop and improves transient response.
• Automotive-grade qualification: AEC‑Q200 rating supports integration into automotive designs requiring component-level qualification.
• Compact, assembly-friendly package: φ12.5 × 25 mm radial can with 5 mm lead spacing simplifies through-hole mounting and board layout.
• Regulatory compliance: RoHS compliant for use in regulated manufacturing environments.
