UPM1E391MPD

The UPM1E391MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can. Designed as part of Nichicon's UPM series, it delivers low impedance and extended endurance for applications that require stable capacitance under elevated temperature and ripple stress.

Key attributes include a 390 µF capacitance at 25 V, AEC-Q200 qualification, a wide operating temperature range of -55°C to +105°C, and a rated life of 5000 hours at 105°C.

Key Features

• Capacitance & Tolerance — 390 µF nominal with a tolerance of -20% to +20% (120 Hz, 20°C).
• Rated Voltage — 25 V DC rating suitable for a variety of through-hole power designs.
• Low Impedance — Specified impedance of 70 mΩ, supporting reduced AC voltage drop under ripple conditions.
• Loss Tangent (tan δ) — tanδ = 0.14 measured at 20°C, 120 Hz, indicating low dielectric losses for the rated conditions.
• High Ripple Current Capability — Low-frequency ripple current 462 mA (120 Hz) and high-frequency ripple current 770 mA (200 kHz) to handle steady and switching ripple loads.
• Leakage Current — Specified leakage current of 292.5 µA after rated voltage application.
• Endurance — 5000 hours at +105°C (meets the UPM series long-life specification for applicable case sizes).
• Temperature Range — Rated for operation from -55°C to +105°C.
• Packaging & Mounting — Radial lead (φ10 × 20L can), lead spacing 5 mm (±0.5 mm), available in bulk or bag packing.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant.

Typical Applications

• Automotive electronic systems — Specified for automotive use and AEC‑Q200 qualified for reliability in vehicle electronics.
• Through-hole PCB assemblies — Radial lead form factor and 5 mm lead spacing for straightforward through-hole mounting and replacement designs.
• High-temperature environments — Rated for continuous operation up to 105°C with 5000-hour endurance for applications exposed to elevated temperatures.

Unique Advantages

• Long operational life: 5000 hours at +105°C provides predictable longevity for designs requiring sustained high-temperature performance.
• Proven reliability standard: AEC‑Q200 qualification supports deployment in environments where component-level qualification is required.
• High ripple-handling capability: Distinct low- and high-frequency ripple current ratings (462 mA at 120 Hz, 770 mA at 200 kHz) address both linear and switching power conditions.
• Compact radial-can footprint: φ10 × 20 mm size with 5 mm lead spacing offers a space-efficient, through-hole solution for power filtering and bulk capacitance needs.
• Low dielectric loss and impedance: tanδ = 0.14 and 70 mΩ impedance reduce power loss and voltage drop under AC conditions.
• Regulatory compliance: RoHS compliance ensures alignment with environmental requirements.
