UHW2A821MHD6

The UHW2A821MHD6 is an 820 µF, 100 V radial lead aluminum electrolytic capacitor from Nichicon’s UHW series. It is a miniature, high‑reliability device designed for general‑purpose power applications that require elevated ripple handling and extended high‑temperature endurance.

Its core strengths include a compact φ18 × 35.5 mm can, high ripple current capability at both low and high frequencies, and a rated lifetime of 12,000 hours at 105°C—making it suitable for demanding power circuits where durability and stable performance matter.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suited for bulk energy storage and DC bus applications within its rating.
• Ripple Current Performance: Low‑frequency ripple current of 2.106 A at 120 Hz and high‑frequency ripple current of 3.51 A at 10 kHz to support AC superposition on DC rails.
• Impedance and Losses: Specified impedance of 81 mΩ and tangent of loss angle (tanδ) of 0.08 measured at 20°C, 120 Hz, for quantifiable AC performance.
• Leakage Current: Leakage current specified at 820 µA for predictable standby and bias behavior.
• High‑Temperature Endurance: Rated lifetime of 12,000 hours at 105°C under rated DC bias plus rated ripple current, supporting long service life in elevated temperature environments.
• Operating Temperature Range: −40°C to +105°C to accommodate a wide range of ambient conditions.
• Package & Mounting: Radial lead can, size φ18 × 35.5 mm, lead spacing 7.5 mm (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for production assembly.
• Compliance & Availability: RoHS compliant and in mass production.

Typical Applications

• General‑purpose power circuits: Bulk smoothing and energy storage in DC power supplies and converters where 100 V ratings and high ripple capacity are required.
• Power electronics modules: Local decoupling and ripple absorption in power stages that demand reliable performance at elevated temperatures and long operational life.
• Industrial equipment: Use in general industrial control and power systems that benefit from the UHW2A821MHD6’s 12,000‑hour endurance at 105°C and defined leakage characteristics.

Unique Advantages

• Quantified ripple handling: Explicit ripple current ratings at 120 Hz (2.106 A) and 10 kHz (3.51 A) let designers size capacitors to measured AC stress levels.
• Long high‑temperature lifetime: 12,000 hours at 105°C under rated conditions provides a clear reliability metric for thermal design and MTBF planning.
• Measured electrical parameters: Specified impedance (81 mΩ), tanδ (0.08 at 20°C/120 Hz), and leakage (820 µA) enable deterministic circuit simulations and margining.
• Compact radial can: φ18 × 35.5 mm packaging with 7.5 mm lead spacing offers a space‑efficient option for through‑hole assemblies.
• RoHS compliant and production ready: Materials compliance and mass production status simplify procurement and lifecycle planning.
