UPM1A391MPD6

The UPM1A391MPD6 is a radial-lead aluminum electrolytic capacitor in Nichicon's UPM series, engineered for low impedance and high reliability in compact power designs. It delivers 390 µF capacitance at a 10 V rating with a polar radial can package (φ10 × 12.5 mm).

Designed for applications that require sustained performance at elevated temperatures, this part provides a 5000-hour load life at 105°C, AEC-Q200 qualification, and RoHS compliance—making it suitable where long-term thermal endurance and qualification are required.

Key Features

• Capacitance & Rated Voltage — 390 µF nominal capacitance with ±20% tolerance; rated for 10 V operation.
• Low Impedance / Controlled Loss — Specified impedance of 150 mΩ and tanδ of 0.19 (measured at 20°C, 120 Hz) for stable AC performance.
• High Ripple Current Capability — Low-frequency ripple current 294 mA at 120 Hz and high-frequency ripple current 490 mA at 200 kHz to support mixed-frequency power stages.
• Leakage Current — Rated leakage current of 117 µA under specified conditions.
• Extended Endurance — 5000-hour load life at +105°C (rated condition) for sustained high-temperature operation.
• Temperature Range — Operating from −55°C to +105°C to cover a wide thermal envelope.
• Package & Mounting — Radial lead can form factor, diameter φ10 mm, length 12.5 mm, lead spacing 5.0 mm; available in bulk or bag packing.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant.

Typical Applications

• Automotive electronic modules — Provides bulk capacitance and ripple handling in control modules and electronic assemblies where AEC-Q200 qualification and 105°C endurance are required.
• Power supply filtering — Low impedance and specified ripple current ratings support smoothing and decoupling in onboard power circuits.
• Compact embedded systems — Small radial footprint (φ10 × 12.5 mm) with 5 mm lead spacing for space-constrained board designs requiring reliable bulk capacitance.

Unique Advantages

• Proven high-temperature endurance: 5000-hour load life at 105°C reduces the need for frequent component replacement in hot environments.
• Compact radial footprint: φ10 × 12.5 mm size with 5 mm lead spacing enables use in dense PCB layouts while providing substantial capacitance.
• High ripple tolerance across frequencies: Rated ripple currents of 294 mA (120 Hz) and 490 mA (200 kHz) address both low- and high-frequency power disturbances.
• Qualification and regulatory readiness: AEC-Q200 qualification and RoHS compliance support regulated designs and environmental requirements.
• Low impedance and controlled dissipation: 150 mΩ impedance and tanδ specified at 120 Hz help maintain stable voltage rails under load.
• Production-ready packaging: Available in bulk or bag packing and listed as mass production status for volume procurement.
