UHE1J821MHD6

The UHE1J821MHD6 is a radial lead aluminum electrolytic capacitor from Nichicon's UHE series, designed for miniature, low-impedance, high-reliability applications. This polarized, radial-can capacitor delivers 820 µF at a 63 V rating in a compact φ18 × 25 mm package with 7.5 mm lead spacing.

Engineered for general-purpose power applications, the component combines low impedance (210 mΩ), defined ripple-current capability at low and high frequencies, and long-life endurance (10,000 hours at 105 °C), making it suitable for designs that require stable capacitance and durability across a wide temperature range.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 63 V rated voltage and a tolerance of −20% to +20% for predictable energy storage and bulk filtering.
• Low Impedance — Rated impedance of 210 mΩ supports reduced voltage ripple and improved transient response in power-handling circuits.
• Ripple Current Handling — Low-frequency ripple current of 1.17 A (120 Hz) and high-frequency ripple current of 1.56 A (10 kHz) to support both mains-frequency filtering and higher-frequency switching environments.
• Loss Characteristics — tan δ (DF) of 0.09 measured at 20 °C, 120 Hz, enabling predictable dissipation behavior in AC/ripple conditions.
• Long Endurance — 10,000-hour rated life at 105 °C under DC bias plus rated ripple current, offering extended service life for continuous-duty applications.
• Wide Operating Temperature — −40 °C to +105 °C operating range to accommodate a broad set of environmental conditions.
• Compact Radial Package — φ18 × 25 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assemblies; available in bulk (no terminal forming) or bag packing.
• RoHS Compliant — Manufactured in accordance with RoHS requirements.

Typical Applications

• Power Supply Filtering — 820 µF capacitance and 63 V rating combined with low impedance make this capacitor suitable for bulk and smoothing duties in power supplies.
• Decoupling and Energy Storage — Capable of handling 120 Hz and 10 kHz ripple currents for decoupling and local energy storage in power conversion stages.
• General-Purpose Electronics — General-purpose radial mounting and long endurance at elevated temperature suit a range of electronic equipment requiring dependable electrolytic capacitance.

Unique Advantages

• High Capacitance in a Small Footprint: 820 µF packaged in a φ18 × 25 mm radial can enables substantial energy storage where board area is constrained.
• Balanced Ripple Performance: Specified ripple currents at both low (1.17 A at 120 Hz) and high (1.56 A at 10 kHz) frequencies allow designers to address mixed-frequency noise and switching environments.
• Predictable Dissipation: A measured tan δ of 0.09 (20 °C, 120 Hz) provides known loss behavior for thermal and reliability assessments.
• Long-Term Reliability: 10,000-hour endurance at 105 °C under rated conditions supports continuous-operation designs and reduces maintenance intervals.
• Through-Hole Robustness: Radial lead mounting with defined lead spacing simplifies insertion and mechanical retention in through-hole assemblies.
• Regulatory Compliance: RoHS-compliant construction addresses environmental and regulatory requirements for modern electronics manufacturing.
