UHE1E392MHD6

The UHE1E392MHD6 is a Nichicon UHE-series miniature aluminum electrolytic capacitor in a radial-lead can. It delivers 3.9 mF capacitance at a 25 V rating with a compact φ18 × 30.5 mm package and 7.5 mm lead spacing.

Designed for high-reliability, general-purpose electronic use, this part combines low impedance, elevated ripple-current handling and long-term endurance (10,000 hours at 105°C) for demanding power-management and filtering roles across industrial and electronic equipment.

Key Features

• Capacitance and Voltage: 3.9 mF (3900 µF) nominal capacitance with a 25 V rated voltage and tolerance of -20% to +20% for predictable energy storage.
• Low Impedance: Rated impedance of 40 mΩ supports effective decoupling and reduced voltage ripple in power circuits.
• High Ripple Current Capability: Low-frequency ripple current of 3.336 A at 120 Hz and high-frequency ripple current of 4.17 A at 10 kHz, enabling reliable AC stress handling.
• Long Life / High Reliability: Endurance rated for 10,000 hours at 105°C under rated voltage and specified ripple conditions, consistent with the UHE series long-life specification.
• Operating Temperature Range: Wide operating range from -40°C to +105°C for stable performance across typical industrial temperature conditions.
• Radial Can Package: φ18 × 30.5 mm cylindrical can with radial leads, 7.5 mm lead spacing (±0.5 mm) and lead diameter 0.8 mm, available in bulk or bag packing for production use.
• Loss Tangent and Leakage: Measured tan δ ≈ 0.18 at 20°C, 120 Hz and leakage current reported as 975 µA, providing electrical characterization for circuit design.
• RoHS Compliant: Conforms to RoHS requirements for use in compliant assemblies.

Typical Applications

• General-purpose electronic circuits: Provides bulk capacitance in board-level designs that require a 3.9 mF energy reservoir at 25 V within a radial-lead form factor.
• Power supply filtering and decoupling: Low impedance and rated ripple currents (3.336 A at 120 Hz, 4.17 A at 10 kHz) make it suitable for smoothing and decoupling in power-management stages.
• Industrial and instrumentation power modules: Long endurance (10,000 hours at 105°C) and a -40°C to +105°C operating range support continuous operation in industrial environments.

Unique Advantages

• Verified long-term endurance: 10,000-hour rating at 105°C gives confidence for designs requiring sustained high-temperature operation.
• High ripple tolerance across frequencies: Specified ripple currents at both 120 Hz and 10 kHz enable designers to account for low- and high-frequency stress without over-designing.
• Compact radial package: φ18 × 30.5 mm can with standardized 7.5 mm lead spacing simplifies placement in through-hole or mixed-technology boards.
• Predictable electrical parameters: Low listed impedance (40 mΩ), measured tan δ, and specified leakage current support accurate circuit simulation and margining.
• RoHS compliance and packaging options: RoHS status and availability in bulk or bag packing accommodate compliant production and inventory workflows.
