UPM0J391MPD

The UPM0J391MPD is a radial lead aluminum electrolytic capacitor from Nichicon's UPM series, designed for high-reliability applications. It delivers 390 µF at 6.3 V in a compact φ8 × 11.5 mm can with 3.5 mm lead spacing and is offered in bulk or bag packaging.

Targeted for demanding environments, this part combines a wide temperature range (−55°C to +105°C), AEC‑Q200 qualification, and a 3000‑hour endurance rating at 105°C to support long‑life electronic systems.

Key Features

• Capacitance & Voltage — 390 µF nominal capacitance at a rated voltage of 6.3 V with ±20% tolerance.
• Low Impedance — Rated impedance of 170 mΩ supports stable performance in power circuits.
• Loss Angle (tan δ) — tanδ of 0.22 measured at 20°C, 120 Hz, providing defined dissipation characteristics for design margin.
• Ripple Current Capability — Low‑frequency ripple current 207 mA (120 Hz) and high‑frequency ripple current 345 mA (200 kHz) for smoothing and decoupling tasks across frequencies.
• Leakage Current — Specified leakage current of 73.71 µA for predictable quiescent behavior.
• High Temperature Endurance — 3000 hours rated life at 105°C for sustained elevated‑temperature operation.
• Operating Temperature Range — −55°C to +105°C supports wide environmental tolerance.
• Package & Mounting — Radial lead (can) construction with 3.5 mm lead spacing and φ8 mm diameter for through‑hole assemblies.
• AEC‑Q200 Qualified — Built to automotive‑grade reliability requirements as indicated by AEC‑Q200 listing.

Typical Applications

• Automotive electronic modules — Provides bulk capacitance and ripple handling for 6.3 V power rails in control units and modules where AEC‑Q200 qualification and high‑temperature endurance are required.
• Power supply smoothing — Compact radial package supplies 390 µF of capacitance and specified ripple current ratings for smoothing and decoupling near regulators and DC‑DC converters.
• Embedded/industrial control — Suitable for through‑hole assemblies in embedded controllers and industrial electronics that demand stable leakage and low impedance over temperature.

Unique Advantages

• Long high‑temperature life: 3000 hours at 105°C provides predictable ageing behavior for designs that operate at elevated temperatures.
• Automotive‑grade reliability: AEC‑Q200 qualification supports use in applications requiring automotive reliability recognition.
• Dual‑frequency ripple ratings: Specified ripple currents at 120 Hz and 200 kHz let designers size capacitance for both low‑ and high‑frequency filtering tasks.
• Compact through‑hole form factor: φ8 × 11.5 mm can with 3.5 mm lead spacing offers a small footprint for space‑constrained PCB layouts while retaining radial lead mounting benefits.
• Predictable electrical characteristics: Defined impedance (170 mΩ), tanδ (0.22), and leakage current (73.71 µA) enable reliable circuit simulation and margining.
