UHW1V821MHD6

The UHW1V821MHD6 is a Nichicon UHW series radial lead aluminum electrolytic capacitor offering 820 µF nominal capacitance at a 35 V rating. It combines a compact φ12.5 × 20 mm can with high ripple-current capability and low impedance at higher frequencies.

Designed for general-purpose electronic applications, this polarized capacitor targets designs that require high ripple handling, compact board footprint, and long-term reliability across a −40 °C to 105 °C operating range.

Key Features

• Capacitance and Voltage: 820 µF nominal capacitance with a 35 V rated voltage and tolerance of −20% to +20% for predictable filtering and energy storage.
• Low Impedance, High Ripple Handling: Specified impedance of 51 mΩ and ripple current capability of 1.56 A at 120 Hz and 2.6 A at 10 kHz to support high-frequency decoupling and power conditioning.
• Loss Characteristics: Tangent of loss angle (tan δ) of 0.11 measured at 20 °C, 120 Hz, providing a clear figure for dissipation behavior under typical conditions.
• Temperature and Endurance: Rated for −40 °C to 105 °C with an endurance life of 10,000 hours at 105 °C under rated conditions for long-term stability.
• Leakage Current: Measured leakage current of 287 µA, specified to support predictable standby and bias behavior after voltage application.
• Package and Mounting: Radial lead can (φ12.5 × 20 mm; L: 2.0 × D: 1.25 cm) with 5 mm lead spacing (±0.5 mm) and bulk/bag packing options for through-hole assembly.
• Compliance: RoHS compliant, aligning with common material-restriction requirements.

Typical Applications

• General-Purpose Electronics: Useful where a compact, polarized electrolytic capacitor is needed for general filtering and energy storage in through-hole designs.
• Power Conditioning: Suited for circuits that require high ripple-current capability and lower impedance at higher frequencies.
• Industrial and Consumer Equipment: Applicable in designs that demand long endurance at elevated temperatures up to 105 °C.

Unique Advantages

• Compact high-capacitance package: φ12.5 × 20 mm can provides substantial capacitance (820 µF) in a small footprint to save board space.
• High ripple-current capability: 1.56 A (120 Hz) and 2.6 A (10 kHz) ratings enable reliable performance in power-conditioning and decoupling roles.
• Low impedance: 51 mΩ impedance supports effective high-frequency performance and reduced voltage ripple across the capacitor.
• Long operational life at elevated temperature: 10,000-hour endurance at 105 °C supports sustained performance in thermally demanding environments.
• Radial lead format: Through-hole radial leads with 5 mm spacing simplify placement and mechanical retention for conventional PCB assembly.
• Regulatory compliance: RoHS compliance supports material-restriction requirements in product development.
