UPTW6820MHD6

The UPTW6820MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can, offering 82 µF capacitance at a 420 V rating. It is part of Nichicon's UPT series, designed for general-purpose power applications where high ripple capability and long operating life are required.

Key value propositions include high ripple current handling, long endurance at elevated temperature, and a compact φ18 × 30.5 mm package with radial lead mounting for easy integration into through-hole assemblies.

Key Features

• Electrical Rating: 82 µF nominal capacitance with a rated voltage of 420 V and polarization indicated for correct orientation.
• Capacitance Tolerance: Specified tolerance of −20% to +20% at 120 Hz, 20°C for predictable design margins.
• Low Loss (tan δ): tanδ = 0.2 (max) measured at 20°C and 120 Hz, supporting stable AC performance.
• High Ripple Current: Rated ripple currents of 570 mA at 120 Hz and 912 mA at 10 kHz to address high-AC-stress applications.
• Leakage Current: Specified leakage current 2,076.4 µA (measured condition documented), enabling designers to budget insulation/leakage behavior.
• Long Endurance: Life rating of 5,000 hours at 105°C under rated DC bias plus rated ripple current, with defined post-test limits for capacitance, tanδ and leakage.
• Temperature Range: Operable from −40°C to +105°C for broad environmental compatibility.
• Package & Mounting: Radial lead can, case size φ18 × 30.5 mm, lead spacing 7.5 mm (±0.5 mm), available in bulk (no terminal forming) or bag packing for assembly flexibility.
• RoHS Compliant: Manufactured to meet RoHS directive requirements.

Typical Applications

• Ballast Circuits: Suited for ballast application where high ripple current capability is required.
• General-Purpose Power Supply Filtering: Used in general-purpose power circuits to provide bulk capacitance and smoothing within the specified voltage and temperature limits.
• Through-Hole Assemblies and Production Runs: Available in bulk or bag packing for prototype and production workflows that accept radial lead components.

Unique Advantages

• High AC Handling: Elevated ripple current ratings at both low and high frequencies (570 mA @120 Hz, 912 mA @10 kHz) reduce thermal stress in AC-loaded circuits.
• Extended High-Temperature Life: 5,000-hour endurance at 105°C supports longer maintenance intervals and predictable aging in hot environments.
• Compact Footprint: φ18 × 30.5 mm can size provides substantial capacitance in a small radial package for space-constrained designs.
• Wide Operating Range: −40°C to +105°C rating enables use across a broad span of operating conditions.
• Design Predictability: Defined leakage current, tanδ measurement conditions, and capacitance tolerance allow accurate modeling of performance over life.
• Assembly Flexibility: Radial lead format with 7.5 mm lead spacing and bulk/bag packing options to support different production processes.
