UHE1E392MHD

The UHE1E392MHD is a radial lead aluminum electrolytic capacitor in Nichicon’s UHE series, offering 3.9 mF (3900 µF) capacitance at a 25 V rating. It is a compact, low-impedance polarized capacitor designed for general-purpose electronic applications that require robust ripple handling and long-term endurance.

Key value propositions include low impedance (44 mΩ), high allowable ripple current at both low and high frequencies, and extended life performance (10,000 hours at 105°C), making it suitable where reliable bulk capacitance and durability are required.

Key Features

• Capacitance & Voltage — 3900 µF nominal capacitance with tolerance of -20% to +20% at a rated voltage of 25 V.
• Low Impedance — Rated impedance of 44 mΩ for improved dynamic performance in power circuits.
• High Ripple Current Capability — Low-frequency ripple current 2.888 A (120 Hz) and high-frequency ripple current 3.61 A (10 kHz), supporting demanding AC ripple environments.
• Endurance — Rated lifetime of 10,000 hours at 105°C under specified conditions, demonstrating long-term reliability for sustained high-temperature operation.
• Leakage Current — Specified leakage current of 975 µA, measured under product conditions.
• Operating Temperature Range — Wide operating range from -40°C to +105°C to support varied thermal environments.
• Package & Mounting — Radial lead can, size φ16 × 35.5 mm length, lead spacing 7.5 mm (±0.5 mm); available in bulk (no terminal forming) and bag packing.
• Regulatory Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and smoothing in general electronic power rails where 25 V rating and high ripple handling are required.
• Industrial electronics — Suited for general-purpose use in industrial control and instrumentation that require long-life capacitors with wide temperature tolerance.
• Consumer and commercial equipment — Use in electronic devices that need compact, reliable bulk energy storage and decoupling within the specified voltage and temperature limits.

Unique Advantages

• High energy density in a compact can: 3.9 mF capacitance in a φ16 × 35.5 mm package delivers significant bulk capacitance where board space is limited.
• Enhanced ripple tolerance: High allowable ripple currents at both 120 Hz and 10 kHz reduce stress on the capacitor in AC-loaded circuits.
• Low ESR/Impedance: 44 mΩ impedance supports improved transient response and lower power loss in power supply applications.
• Long-term durability: 10,000 hours at 105°C rated life provides predictable aging and replacement planning for long-life designs.
• Wide operating range: −40°C to +105°C supports deployment across a broad set of thermal environments.
• RoHS compliant and standard packaging: Meets RoHS requirements and is available in bulk or bag packing for straightforward procurement and assembly handling.
