UHD1H821MHD6

The UHD1H821MHD6 is a miniature, radial-lead aluminum electrolytic capacitor designed for general-purpose power applications. It combines an 820 µF capacitance with a 50 V rating in a compact φ16 × 20 mm can to provide bulk energy storage and smoothing in board-level power circuits.

Engineered for high ripple current and low impedance at higher frequencies, this Nichicon UHD-series component supports operating temperatures from −40°C to +105°C and an endurance rating of 5000 hours at 105°C, making it suitable for longer-life industrial and electronic designs.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 50 V rated voltage and a capacitance tolerance of −20% to +20% for predictable bulk storage.
• Low Loss (tan δ) — tanδ of 0.10 measured at 20°C, 120 Hz, supporting efficient operation with lower dissipation under typical ripple conditions.
• High Ripple Current Capability — Rated low-frequency ripple current of 2047.5 mA at 120 Hz and high-frequency ripple current of 2730 mA at 100 kHz to handle demanding AC ripple on power rails.
• Leakage Current — Specified leakage current of 410 µA (after rated conditions), allowing designers to budget for standby and quiescent currents.
• Robust Endurance — Life/endurance specified as 5000 hours at 105°C, with post-test limits for capacitance change, tanδ, and leakage current defined in the datasheet.
• Compact Radial Package — φ16 × 20 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole assembly and secure board attachment. Available in bulk or bag packing with no terminal forming.
• Wide Operating Temperature — Rated for −40°C to +105°C to accommodate a broad range of environmental conditions.
• RoHS Compliant — Conforms to RoHS requirements as stated in the product data.

Typical Applications

• Power Supply Filtering — Bulk decoupling and smoothing on DC power rails where 820 µF and high ripple capability reduce voltage ripple and support stable regulation.
• DC–DC Converter Output — Energy storage and ripple handling on converter outputs that require compact, high-ripple components.
• Industrial Electronics — Board-level power systems operating across −40°C to +105°C that benefit from long endurance (5000 h at 105°C) and robust ripple handling.

Unique Advantages

• High ripple handling in a small can: Rated ripple currents of 2.047 A (120 Hz) and 2.73 A (100 kHz) enable effective AC ripple management without large case sizes.
• Long endurance at elevated temperature: 5000-hour life at 105°C supports reliable operation in demanding thermal environments.
• Low dissipation (tanδ = 0.10): Lower loss at 120 Hz helps reduce self-heating and improves efficiency in power circuits.
• Compact radial package: φ16 × 20 mm can with 7.5 mm lead spacing provides a space-efficient through-hole solution for PCB-level energy storage.
• Predictable leakage behavior: Specified leakage current of 410 µA allows accurate power budgeting for standby and low-current modes.
• RoHS compliant and production-ready: Compliant with RoHS and listed as mass production, simplifying procurement and design integration.
