UPM1E392MHD

The UPM1E392MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, offering 3.9 mF capacitance at a 25 V rating. Designed for applications that require low impedance, extended high-temperature endurance and robust ripple handling, this part supports demanding operating ranges and long load-life requirements.

Key value propositions include low impedance (19 mΩ), long endurance (5000 hours at 105°C), and AEC-Q200 qualification for applications that demand proven reliability across a wide temperature range of −55°C to 105°C.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 25 V with ±20% tolerance for bulk energy storage and decoupling in power circuits.
• Low Impedance — 19 mΩ specified impedance to minimize voltage drop and improve transient response on power rails.
• High Ripple Handling — Ripple current capability of 4.324 A at 120 Hz and 2.79 A at 1 kHz to support high-stress power applications.
• Extended Endurance — 5000 hours rated life at 105°C, supporting long-term operation under elevated temperature and DC bias.
• Wide Temperature Range — Operating from −55°C to 105°C for reliable performance across harsh environments.
• Package & Mounting — Radial lead can (φ16 × 40L) with 7.5 mm lead spacing; supplied in bulk (no terminal forming) or bag packing for through-hole assembly.
• Quality & Compliance — AEC-Q200 rated and RoHS compliant for regulated and reliability-focused designs.
• Leakage and Loss — Specified leakage current 2925 µA and tangent of loss angle (tanδ) 0.26 to characterize leakage and dissipation behavior.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification, −55°C to 105°C range and 5000 h endurance at 105°C make the part suitable for automotive electronic systems that need durable bulk capacitance and ripple handling.
• High-Ripple Power Modules — Rated ripple current (4.324 A @ 120 Hz, 2.79 A @ 1 kHz) supports DC-link smoothing and power supply filtering in designs with significant ripple stress.
• Rugged Industrial Equipment — Wide operating temperature and long-life rating support use in industrial systems requiring stable capacitance and low impedance over time and temperature.

Unique Advantages

• Endurance for Elevated Temperatures: 5000-hour life at 105°C provides measurable long-term reliability under sustained thermal stress.
• High Ripple Capability: Clear ripple current ratings at both low and high frequency (120 Hz and 1 kHz) enable designers to match the component to real-world switching and ripple conditions.
• Low-Impedance Performance: 19 mΩ impedance reduces power loss and improves transient response on power rails.
• AEC-Q200 Qualification: Supports designs that require industry-recognized reliability standards for automotive and similarly demanding applications.
• Through-Hole Form Factor: Radial-lead can and 7.5 mm lead spacing simplify placement and mechanical retention in through-hole assemblies.
• Compliance and Availability: RoHS compliant and listed as mass production, with packaging options (bulk or bag) to suit manufacturing needs.
