UPM1A391MPD

The UPM1A391MPD is a Nichicon UPM-series miniature aluminum electrolytic capacitor in a radial‑lead can. It delivers 390 µF capacitance at a 10 V rating with low impedance characteristics and high reliability for demanding environments.

Designed for applications that require compact energy storage and ripple handling, this AEC‑Q200 qualified component targets automotive and other high‑reliability markets where temperature endurance and stable performance matter.

Key Features

• Capacitance and Voltage: 390 µF nominal capacitance with a rated voltage of 10 V and tolerance of -20% to +20%.
• Low Impedance Performance: Specified impedance of 140 mΩ and a tangent of loss angle (tan δ) of 0.19 measured at 20°C, 120 Hz, supporting efficient smoothing and decoupling.
• Ripple Current Capability: Low‑frequency ripple current of 258 mA (120 Hz) and high‑frequency ripple current of 430 mA (200 kHz), enabling effective AC ripple handling across frequency ranges.
• Leakage Current: Leakage current rated at 117 µA, specified under the product conditions.
• High Reliability Endurance: Rated for 3000 hours at 105°C, consistent with the UPM series’ endurance specifications for smaller case sizes.
• Wide Temperature Range: Operating range from -55°C to +105°C for use in thermally challenging environments.
• Compact Radial Can Package: φ8 × 15 mm can with 3.5 mm lead spacing (±0.5 mm), supplied as radial lead, can package with bulk or bag packing options.
• Compliance and Qualification: RoHS compliant and AEC‑Q200 rated per the product specifications.

Typical Applications

• Automotive Electronics: Use in automotive control modules and subsystems where AEC‑Q200 qualification and 105°C endurance provide required reliability and thermal margin.
• Power Filtering and Decoupling: Bulk smoothing and decoupling on compact power rails, leveraging 390 µF capacitance, 140 mΩ impedance, and specified ripple currents for stable DC outputs.
• Compact Power Modules: Output filtering for DC–DC converters and small power supplies where a small φ8 × 15 mm footprint and radial‑lead mounting are advantageous.

Unique Advantages

• AEC‑Q200 Qualification: Provides confidence for automotive and other high‑reliability system selection where component qualification is required.
• Balanced Ripple Handling: Dual ripple ratings (258 mA at 120 Hz and 430 mA at 200 kHz) support both low‑ and high‑frequency noise suppression.
• Thermal Endurance: 3000‑hour life at 105°C ensures sustained performance in elevated temperature applications.
• Compact, Serviceable Form Factor: Small φ8 × 15 mm radial can with 3.5 mm lead spacing simplifies retrofits and through‑hole PCB layouts.
• Low Losses: Specified tan δ of 0.19 and 140 mΩ impedance deliver efficient energy storage with minimized dissipation at test conditions.
• Production‑Ready Supply: Available in bulk or bag packing and listed as mass production status for volume applications.
