UPJ1E392MHD6

The UPJ1E392MHD6 is a radial-lead aluminum electrolytic capacitor with a nominal capacitance of 3,900 µF (3.9 mF) and a 25 V rated voltage. It is built for general-purpose power applications where robust bulk capacitance, high ripple handling and long operating life are required.

Designed as part of Nichicon's UPJ series, this can-style capacitor provides low-impedance performance and a long endurance rating, making it suited to power-filtering and energy-storage roles in switching power supplies and related equipment.

Key Features

• Capacitance & Voltage — 3,900 µF nominal capacitance with a 25 V rated voltage and tolerance of −20% to +20% for bulk energy storage and smoothing.
• Low-impedance design — Series-level UPJ characteristics indicate low impedance suitable for switching power supply filtering and decoupling tasks.
• Ripple current capability — Rated ripple current of 2.178 A at 120 Hz and 2.42 A at 200 kHz to handle AC stress across low and high-frequency environments.
• Electrical loss and leakage — Tangent of loss angle (tan δ) of 0.18 measured at 20°C, 120 Hz (25 V), and a specified leakage current of 2,925 µA under test conditions.
• Long endurance — Load-life rating of 5,000 hours at 105°C, supporting continuous operation under elevated temperature and ripple conditions.
• Radial can package — φ18 × 35.5 mm can with radial leads, 7.5 mm lead spacing (±0.5 mm), suited to through-hole assemblies; available in bulk or bag packing.
• Wide operating temperature — Rated for −55°C to +105°C to cover a broad range of industrial and commercial operating environments.
• RoHS compliant — Meets RoHS environmental requirements as specified in the product data.

Typical Applications

• Switching power supplies — Bulk smoothing and output filtering where low impedance and high ripple capability improve regulation and stability.
• DC–DC converters — Energy storage and decoupling for converters requiring sustained ripple current handling and long operating life.
• Industrial power modules — Filtering and buffering in industrial electronics that operate across −55°C to +105°C.
• General-purpose power filtering — Use in general-purpose boards and assemblies that need robust through-hole bulk capacitance.

Unique Advantages

• Long-term reliability: 5,000-hour load-life rating at 105°C supports sustained operation under thermal and electrical stress.
• High ripple tolerance: Specified ripple currents at both low (120 Hz) and high (200 kHz) frequencies reduce heating and improve filtering performance under varying switching conditions.
• Low-impedance behavior: UPJ series design emphasis on low impedance enhances performance in switching power supply applications.
• Through-hole robustness: Radial-can package and 7.5 mm lead spacing simplify mounting and replacement in through-hole designs.
• Compact bulk capacitance: 3,900 µF in a φ18 × 35.5 mm can provides significant energy storage in a relatively small footprint for can-style aluminum electrolytics.
• Regulatory compliance: RoHS-compliant construction supports environmental and manufacturing requirements.
