UHE1A392MHD6

The UHE1A392MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHE series. It is a radial‑lead, polarized device rated at 10 V with 3.9 mF (3900 µF) capacitance, designed for general-purpose electronic applications.

Key value points include low impedance (78 mΩ), robust ripple handling at both low and high frequencies, and long endurance (8000 hours at 105°C), all in a compact φ16 × 20 mm can with 7.5 mm lead spacing.

Key Features

• Electrical Performance 3.9 mF nominal capacitance at 10 V with ±20% tolerance and polarization for board-level bulk energy storage and smoothing.
• Low Impedance & Loss Specified impedance of 78 mΩ and measured tanδ (DF) of 0.23 at 20°C, 120 Hz for stable AC performance.
• Ripple Current Capability Rated low-frequency ripple current 2.024 A at 120 Hz and high-frequency ripple current 2.53 A at 10 kHz, with frequency coefficients defined for larger capacitances.
• Leakage and Stability Leakage current specified at 390 µA and capacitance tolerance of -20% to +20% for predictable behavior in DC applications.
• Reliability & Lifetime Endurance rating of 8000 hours at 105°C (for the 10 V rating and this case size), supporting extended operation in high-temperature environments.
• Mechanical & Packaging Radial lead, can package with dimensions φ16 × 20 mm, lead spacing 7.5 mm (±0.5 mm). Available in bulk (no terminal forming) or bag packing; product is in mass production.
• Temperature Range & Compliance Operational from -40°C to +105°C and RoHS compliant.

Typical Applications

• General-purpose electronic equipment — Bulk smoothing and decoupling where a compact, high-capacitance polarized capacitor is required.
• Power supply filtering — Low impedance and significant ripple current capability help reduce voltage ripple in DC power rails.
• Energy storage for system support — Compact capacitance for short-term energy buffering in general-purpose circuits.

Unique Advantages

• High capacitance in a compact can: 3.9 mF in a φ16 × 20 mm package conserves PCB space while providing substantial bulk capacitance.
• Low impedance for improved ripple performance: 78 mΩ impedance combined with specified ripple currents reduces AC loss and voltage fluctuation under load.
• Dual-frequency ripple handling: Defined low- and high-frequency ripple current ratings (2.024 A at 120 Hz and 2.53 A at 10 kHz) support mixed-frequency power environments.
• Long endurance at elevated temperature: 8000 hours at 105°C supports sustained operation in warm operating conditions.
• Through-hole radial lead format: Easy to handle and install for prototyping, repairable assemblies, and through-hole manufacturing flows.
• RoHS compliant and production-ready: Environmentally compliant and available in bulk or bag packing; product is in mass production.
