UHV0J821MPD

The UHV0J821MPD from Nichicon is an aluminum electrolytic capacitor in the UHV series, configured as a radial-lead can. It provides 820 µF capacitance at a rated voltage of 6.3 V and is designed for general-purpose circuit use where high ripple tolerance, low impedance and compact size are required.

Key value propositions include low impedance (181 mΩ), high ripple current capability (594 mA at 120 Hz and 990 mA at 100 kHz), long endurance (6,000 hours at 105°C), and a wide operating temperature range from −40°C to +105°C.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 6.3 V with a tolerance of −20% to +20%.
• Low Impedance — Specified impedance of 181 mΩ to support lower voltage ripple and improved transient response.
• High Ripple Current — 594 mA at 120 Hz (low frequency) and 990 mA at 100 kHz (high frequency) for demanding ripple conditions.
• Long Endurance — 6,000 hours rated life at 105°C under DC bias plus rated ripple current.
• Wide Temperature Range — Operates from −40°C to +105°C for broad environmental coverage.
• Radial Lead Packaging — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) for straightforward through-hole assembly; supplied in bulk or bag packing.
• Low Leakage — Calculated leakage current of 51.66 µA after 2 minutes’ application of rated voltage at 20°C (per datasheet formula: 0.01CV).
• RoHS Compliant — Meets RoHS environmental requirements.

Typical Applications

• General Purpose — For circuits that require 820 µF capacitance at 6.3 V with reliable ripple handling and long endurance.
• Board-Level Filtering — Suited to through-hole implementations needing low impedance and elevated ripple current capability.
• Industrial and Commercial Electronics — Use in general-purpose electronic assemblies requiring operation from −40°C to +105°C and 6,000-hour endurance.

Unique Advantages

• Compact, high-capacity form factor: φ8 × 11.5 mm can delivers 820 µF in a small radial-lead package for space-constrained layouts.
• High-frequency performance: Low impedance (181 mΩ) and a 990 mA ripple rating at 100 kHz support effective decoupling at higher switching frequencies.
• Durability under stress: 6,000-hour endurance at 105°C provides predictable life performance in elevated-temperature conditions.
• Predictable leakage behavior: Leakage current specified (51.66 µA at 20°C after 2 minutes) using the manufacturer’s leakage formula for design margin calculations.
• Through-hole ease-of-use: Radial lead design with defined 3.5 mm lead spacing (±0.5 mm) simplifies hand or automated through-hole assembly options.
• Regulatory compliance: RoHS compliance supports environmentally constrained designs.
