UPM1V391MPD

The UPM1V391MPD is a miniature radial-lead aluminum electrolytic capacitor in Nichicon’s UPM series, designed for high-reliability power filtering and decoupling. It is a polarized, low-impedance device specified at 390 µF and 35 V with a compact φ10 × 25 mm can and 5 mm lead spacing.

Engineered for demanding thermal and ripple environments, this part offers long endurance at elevated temperature and industry-recognized qualification suitable for robust electronic designs.

Key Features

• Electrical Performance  390 µF capacitance at 35 V rated voltage with ±20% tolerance; tanδ (DF) = 0.12 measured at 20°C, 120 Hz.
• Low Impedance & Ripple Handling  Low impedance (55 mΩ) and rated ripple currents of 588 mA at 120 Hz and 980 mA at 200 kHz support dynamic power-rail stabilization and high-frequency decoupling.
• High Reliability Endurance  Life rating of 5000 hours at +105°C under rated voltage and ripple conditions, with leakage current specified at 409.5 µA for this part.
• Mechanical & Mounting  Radial lead, polarized can package (φ10 × 25 mm) with 5.0 mm lead spacing (±0.5 mm tolerance); available in bulk or bag packing (no terminal forming).
• Wide Temperature Range  Specified for −55°C to +105°C operation to support designs exposed to broad ambient conditions.
• Qualification & Compliance  AEC-Q200 rating is listed for the series and the part is RoHS compliant, indicating suitability for qualified automotive and high-reliability applications.

Typical Applications

• Automotive electronic modules  Bulk decoupling and filtering in control modules where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC converters and power supplies  Input/output smoothing and transient suppression using the part’s high ripple-current capability and low impedance.
• Industrial controllers  Power-rail stabilization in systems operating across −55°C to +105°C.
• Backup power and energy-holding circuits  Local energy storage and bulk filtering where compact size and reliable endurance are important.

Unique Advantages

• Long elevated-temperature life: 5000 hours at +105°C provides predictable end-of-life planning for high-temperature applications.
• AEC-Q200 series qualification: Series-level AEC-Q200 listing supports use in automotive electronics and other high-reliability markets.
• High-frequency capability: 980 mA ripple at 200 kHz enables effective decoupling in switching regulator and high-speed power stages.
• Compact radial can: φ10 × 25 mm package with 5 mm lead spacing simplifies through-hole assembly in space-constrained designs.
• Low leakage and low loss: Specified leakage current and tanδ (0.12 at 20°C, 120 Hz) help maintain efficiency and predictable behavior over temperature and life.
• RoHS compliant: Conforms to RoHS requirements for environmental compliance in commercial and automotive products.
