UPW1J391MHD6

The UPW1J391MHD6 is a miniature, high‑reliability aluminum electrolytic capacitor in a radial‑lead can from Nichicon's UPW series. It is a 390 µF, 63 V polarized capacitor engineered for low impedance and extended endurance in demanding power applications.

Designed for switching power supplies and electronic control systems, this part delivers sustained performance across a wide temperature range (−55°C to 105°C) and is AEC‑Q200 rated for automotive use where applicable.

Key Features

• Capacitance & Voltage: 390 µF rated capacitance at 63 V for bulk energy storage and smoothing.
• Low Loss & Impedance: tanδ 0.09 (measured at 20°C, 120 Hz) and a specified impedance of 172 mΩ to minimize voltage ripple and improve transient response.
• High Ripple Current Capability: 1.268 A at 120 Hz (low frequency) and 1.69 A at 10 kHz (high frequency) to handle switching converter ripple and high‑frequency current components.
• Leakage Current: Specified leakage current of 737.1 µA for predictable standby and bias behavior.
• Long Endurance: Rated life of 8000 hours at 105°C, supporting long service intervals in high‑temperature installations.
• Wide Operating Temperature: −55°C to 105°C suitable for harsh environments.
• Radial Lead Package: φ18 × 15 mm can with 7.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly.
• AEC‑Q200 Rated: Meets AEC‑Q200 requirements, indicating suitability for automotive electronic applications.
• Production Status: Mass production availability for volume designs.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering where low impedance and high ripple current capability reduce output ripple and improve stability.
• Automotive Electronics: Energy storage and decoupling in control modules and power distribution systems, leveraging the AEC‑Q200 rating and wide temperature range.
• DC‑DC Converters and Power Modules: Input/output filtering for high‑frequency converters where sustained ripple handling and low ESR are required.
• Industrial Control Equipment: Power buffering and transient suppression in systems operating in elevated temperatures or harsh conditions.

Unique Advantages

• High ripple handling: Specified ripple currents at both 120 Hz and 10 kHz support both low‑ and high‑frequency converter designs.
• Long high‑temperature life: 8000 hours at 105°C extends service life in hot operating environments and reduces replacement frequency.
• Low impedance and loss: 172 mΩ impedance and tanδ 0.09 (63 V rating) help minimize voltage drop and heat generation under load.
• AEC‑Q200 qualification: Provides a pathway for use in automotive and similarly demanding applications that require recognized component-level robustness.
• Compact radial package: φ18 × 15 mm can with 7.5 mm lead spacing offers a space‑efficient option for through‑hole PCB layouts.
• Production readiness: Mass production status and standard packaging options support rapid procurement and assembly planning.
