UPM1C391MPD

The UPM1C391MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series designed for low-impedance, high-reliability power applications. It provides 390 µF capacitance at a 16 V rating with a compact φ8×20 mm can and 3.5 mm lead spacing, supplied in bulk for mass production.

Built for sustained elevated-temperature operation, this part offers a 3000-hour endurance at +105°C, AEC-Q200 qualification, and an extended operating range from −55°C to +105°C, making it suitable for demanding electronics designs where long-term stability and robustness are required.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance at 16 V with ±20% tolerance for predictable energy storage and decoupling performance.
• Low Impedance — Specified impedance of 100 mΩ to reduce losses and support lower ripple on power rails.
• Ripple Current Capability — 342 mA at 120 Hz (low frequency) and 570 mA at 200 kHz (high frequency) to handle AC stress in power circuits.
• Leakage and Dissipation — Controlled leakage current of 187.2 µA and tanδ of 0.16 for stable electrical characteristics.
• High-Temperature Endurance — Rated lifetime of 3000 hours at +105°C to support prolonged high-temperature operation.
• Automotive-Grade Qualification — AEC-Q200 qualified for use in automotive electronics and related high-reliability markets.
• Package & Mounting — Radial can package (φ8×20L) with 3.5 mm lead spacing and bulk/no terminal forming supply for high-volume assembly.
• Wide Operating Range — −55°C to +105°C operating temperature range for use across a broad set of thermal environments.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Automotive electronics — AEC-Q200 qualification and 3000-hour endurance at 105°C make it suitable for automotive electronic modules requiring reliable electrolytic capacitance.
• Mass-production OEM assemblies — Supplied in bulk with no terminal forming to support automated, high-volume manufacturing workflows.
• Elevated-temperature systems — Rated for −55°C to +105°C and long-duration operation at 105°C for designs exposed to sustained heat.

Unique Advantages

• Automotive-grade reliability: AEC-Q200 qualification provides the traceable ruggedness expected for automotive and demanding industrial applications.
• High ripple tolerance: Dual ripple-current specs (342 mA at 120 Hz and 570 mA at 200 kHz) support performance across both low- and high-frequency noise environments.
• Low-loss operation: 100 mΩ impedance and tanδ of 0.16 minimize power dissipation and improve efficiency in power circuits.
• Long-term thermal endurance: 3000-hour rating at +105°C delivers predictable life in hot operating conditions.
• Production-ready packaging: Bulk/no terminal forming format is optimized for high-volume PCB assembly and reduced handling steps.
• Compact radial can: φ8×20 mm can and 3.5 mm lead spacing allow dense board placement while retaining axial stability.
