UHV1V821MHD

The UHV1V821MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHV series, offering 820 µF capacitance at a 35 V rating. It is engineered for general-purpose electronic applications that require high ripple handling and low impedance in a compact radial can.

As part of the UHV family, this part emphasizes lower impedance at high frequency, elevated ripple-current capability, and long endurance at elevated temperature, making it suitable for demanding power and decoupling roles in electronic designs.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance (–20% to 20%).
• Low Impedance: Rated impedance of 41 mΩ provides improved AC performance and reduced voltage drop under ripple conditions.
• High Ripple Current: Low-frequency ripple current of 1.635 A (120 Hz) and high-frequency ripple current of 2.725 A (100 kHz) to support demanding power rails.
• Tangent of Loss Angle (tan δ): tanδ = 0.11 specified at 20°C, 120 Hz for the 35 V rating, supporting efficient energy dissipation.
• Endurance: Rated life of 6000 hours at 105°C under specified conditions, with performance criteria for capacitance, tanδ and leakage current after endurance testing.
• Temperature Range: Operates from –40°C to +105°C to cover a wide span of environmental conditions.
• Mechanical & Mounting: Radial lead can with dimensions φ12.5 × 20 mm and lead spacing 5.0 mm (±0.5 mm), suitable for through-hole mounting.
• Leakage Current: Specified leakage current value of 287 µA (measured per product data conditions).
• Packaging & Status: Available in bulk (no terminal forming) or bag packing; part is in mass production and RoHS compliant.

Typical Applications

• General-Purpose Power Filtering: Used to stabilize and smooth DC rails where high capacitance and strong ripple capability are required.
• Decoupling on Power Modules: Provides bulk energy storage and low-impedance support for power converters and regulator outputs.
• Industrial and Consumer Electronics: Fits through-hole designs that need robust thermal endurance (–40°C to 105°C) and long operational life (6000 h at 105°C).

Unique Advantages

• High ripple-handling capability: Quantified ripple ratings at 120 Hz and 100 kHz allow designers to select the part with known AC performance.
• Low impedance across frequency: 41 mΩ impedance and UHV-series design reduce voltage drop and improve transient response on power rails.
• Compact radial can: φ12.5 × 20 mm package provides high capacitance in a small footprint for through-hole assemblies.
• Long high-temperature life: 6000 hours at 105°C supports extended service life in thermally stressed applications.
• Clear manufacture and compliance: Mass-production status and RoHS compliance simplify procurement and regulatory alignment.
