UHE1E332MHD6

The UHE1E332MHD6 is a Nichicon UHE-series miniature aluminum electrolytic capacitor designed for high-reliability, long-life applications. It is a radial-lead, polarized capacitor offering 3300 µF nominal capacitance at a 25 V rating, optimized for general-purpose electronic circuits requiring compact bulk capacitance and sustained performance across a wide temperature range.

Key value propositions include low impedance (49 mΩ), high ripple-current capability at both low and high frequencies, and endurance specified up to 10,000 hours at 105 °C, making it suitable for designs where sustained ripple handling and long-term stability are required.

Key Features

• Capacitance & Voltage — 3300 µF nominal capacitance with ±20% tolerance at 25 °C, rated for 25 V DC.
• Low Impedance — Specified impedance of 49 mΩ for reduced voltage drop under load and improved transient response.
• High Ripple Current Handling — Low-frequency ripple current 2.512 A (120 Hz) and high-frequency ripple current 3.14 A (10 kHz) to support power smoothing and decoupling in dynamic circuits.
• Long Endurance — Rated for 10,000 hours at 105 °C (UHE series endurance rating for 16–100 V range), supporting extended operational life under elevated temperature and bias.
• Wide Operating Temperature — Specified operating range from −40 °C to +105 °C, with defined impedance stability at low temperatures.
• Mechanical & Mounting — Radial lead can package, size φ18 × 25L (L: 2.5 × D: 1.8 cm), lead spacing 7.5 mm with 0.5 mm tolerance, suitable for through-hole assemblies.
• Leakage Current & Polarization — Leakage current specified at 825 µA; capacitor is polarized and must be used with correct polarity.
• Environmental Compliance & Packaging — RoHS compliant; available in Bulk (No Terminal Forming) and Bag packing options.
• Tangential Loss Guidance — Datasheet specifies tan δ max for 25 V units (0.14 at 120 Hz) and notes an incremental increase for capacitances above 1000 µF as defined by the series datasheet.

Typical Applications

• General-purpose electronic circuits — Use where a compact, high-capacitance polarized capacitor is required for bulk energy storage and supply stabilization within −40 °C to +105 °C operating environments.
• Power supply filtering — Suitable for smoothing and ripple suppression in DC power rails at up to 25 V, leveraging the specified ripple-current ratings and low impedance.
• Industrial and commercial equipment — Applicable to equipment designs needing long-duration endurance (10,000 hours at 105 °C) and reliable performance under elevated temperature and continuous bias.

Unique Advantages

• High ripple tolerance: 2.512 A at 120 Hz and 3.14 A at 10 kHz lets designers manage both low- and high-frequency ripple without overspecifying multiple components.
• Long operational life at elevated temperature: 10,000-hour endurance at 105 °C provides predictable aging and maintenance planning for thermal-stressed applications.
• Compact radial-lead form factor: φ18 × 25L package with 7.5 mm lead spacing delivers significant capacitance in a small through-hole footprint for space-constrained boards.
• Low impedance: 49 mΩ specification supports better transient response and lower ripple voltage under load.
• RoHS compliant: Meets environmental compliance requirements for modern electronic assemblies.
• Available packaging options: Bulk and bag packing choices simplify procurement and handling for different production volumes.
