UPTW6820MHD

The UPTW6820MHD is an aluminum electrolytic capacitor in Nichicon's UPT series designed for high-voltage, high-ripple applications. It is a miniature radial-lead can optimized for long life and reliable performance in general-purpose and ballast circuits.

With a rated capacitance of 82 µF at 420 V and a compact 4 cm × 1.6 cm footprint, the UPTW6820MHD delivers measurable ripple-current capability and endurance for power-conditioning roles where space and thermal robustness matter.

Key Features

• High Voltage & Capacitance — 82 µF rated capacitance at 420 V provides energy storage suitable for high-voltage circuits.
• High Ripple Current Performance — Rated ripple: 570 mA at 120 Hz and 912 mA at 10 kHz, supporting AC ripple handling across common frequencies.
• Long Life Endurance — Engineered for 5000 hours at 105 °C under rated conditions, with specified limits for capacitance change, tan δ, and leakage current after endurance testing.
• Wide Operating Temperature Range — Specified for −40 °C to +105 °C, enabling use across challenging thermal environments.
• Compact Radial-Lead Package — Radial can package with 7.5 mm lead spacing and a small footprint (L: 4 cm × D: 1.6 cm) for dense board layouts and through-hole assembly.
• Polarized, General-Purpose Design — Polarized aluminum electrolytic construction with ±20% capacitance tolerance at 120 Hz, 20 °C for typical circuit design margins.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Ballast Circuits — Suited for ballast application where high ripple current capability and high voltage rating are required.
• General-Purpose High-Voltage Power Circuits — Energy storage, filtering and smoothing roles in compact high-voltage supply designs.
• Compact Through-Hole Assemblies — Radial-lead can and small footprint make it a fit for space-constrained, serviceable boards where robustness is needed.

Unique Advantages

• Measured Ripple Handling: Specified ripple currents at both 120 Hz and 10 kHz enable designers to account for performance across low and high-frequency ripple conditions.
• High-Voltage Capability: 420 V rating supports designs that require elevated DC voltage margins without upsizing the capacitor.
• Compact Footprint: Small can size (4 cm × 1.6 cm) with 7.5 mm lead spacing helps reduce board area while maintaining through-hole reliability.
• Robust Thermal Endurance: 5000 hours at 105 °C provides predictable life performance in thermally demanding applications.
• Design-Friendly Tolerance: ±20% capacitance tolerance and polarized construction simplify selection and integration into power designs.
• Regulatory Compliance: RoHS compliance eases environmental and supply-chain considerations.
