UPM1V391MHD6

The UPM1V391MHD6 is a radial-lead aluminum electrolytic capacitor designed for demanding power applications. Part of Nichicon’s UPM series, it combines a compact φ12.5 × 15 mm can with low impedance and extended endurance for use across wide temperature ranges.

Targeted at systems that require robust power smoothing and ripple handling, this capacitor supports automotive-class designs with AEC-Q200 qualification and is RoHS compliant. Its defining value propositions are reliable long-term operation at elevated temperature and strong ripple-current capability.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance at 35 V, with tolerance of −20% to +20% for predictable energy storage and decoupling.
• Low Impedance — Specified impedance of 60 mΩ, enabling efficient filtering and reduced voltage ripple in power rails.
• High Ripple Current Capability — Low-frequency ripple current of 495 mA (120 Hz) and high-frequency ripple current of 825 mA (200 kHz) to support DC bus smoothing and converter outputs.
• Long Endurance — 5000 hours rated life at +105°C, providing durability for prolonged elevated-temperature operation.
• Wide Operating Temperature — −55°C to +105°C operating range suitable for harsh environments and wide ambient swings.
• Compact Radial Package — φ12.5 × 15 mm can with 5 mm lead spacing and radial-lead mounting for through-hole assemblies and bulk/bag packing options.
• Leakage & Loss Characteristics — Leakage current specified at 409.5 µA and dissipation factor (tan δ) of 0.12 measured at 20°C, 120 Hz, enabling designers to budget for standby loss and ESR-related heating.
• Automotive-Grade Qualification — AEC-Q200 rating and RoHS compliance for regulated applications.

Typical Applications

• Automotive Power Systems — Bulk energy storage and smoothing in control modules and power-supply circuits where AEC-Q200 qualification and wide temperature range are required.
• DC–DC Converters — Input/output filtering in converters that demand high ripple-current capability and low impedance to maintain stable rail voltages.
• Industrial Electronics — Power filtering and decoupling in industrial control equipment operating across −55°C to +105°C.

Unique Advantages

• Proven High-Temperature Endurance: 5000-hour life at +105°C reduces maintenance and replacement frequency in hot environments.
• Strong Ripple Handling: Dual-spec ripple currents (495 mA @120 Hz, 825 mA @200 kHz) let designers select this part for both low- and high-frequency ripple suppression.
• Compact Through-Hole Form Factor: φ12.5 × 15 mm radial can with 5 mm lead spacing saves board area while remaining easy to mount and replace.
• Quantified Electrical Losses: 60 mΩ impedance and tan δ = 0.12 (20°C, 120Hz) allow accurate thermal and performance modeling in power designs.
• Automotive-Grade Confidence: AEC-Q200 rating and RoHS compliance help meet industry requirements for regulated applications.
