UPZ2W820MHD6

The UPZ2W820MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPZ series. It is a polarized, radial-lead can-type capacitor specified for general-purpose high-voltage applications.

Key attributes include a 450 V rated voltage, 82 µF capacitance with ±20% tolerance, compact dimensions (L: 3.05 × D: 1.8 cm), an operating temperature range of –40 °C to +105 °C, and a 2000-hour endurance rating at 105 °C—features that support compact, robust designs requiring elevated voltage and thermal endurance.

Key Features

• High Voltage Rating (450 V) — Rated for up to 450 V DC, supporting higher-voltage circuits within a compact package.
• Capacitance & Tolerance — 82 µF nominal capacitance with tolerance of −20% to +20% at 120 Hz, 20 °C.
• Compact Radial Can Package — Radial lead, can-style package with lead spacing 7.5 mm and physical size L: 3.05 × D: 1.8 cm for through-hole mounting in space-constrained layouts.
• Wide Temperature Range & Endurance — Rated for –40 °C to +105 °C and specified for 2000 hours at 105 °C under DC bias plus rated ripple current.
• Ripple Current Performance — Rated ripple current of 550 mA at 120 Hz and 825 mA at 10 kHz, with frequency coefficients defined in the UPZ series specification.
• Leakage and Dissipation Characteristics — Leakage current specified as not more than 0.04CV + 100 µA (after 1 minute at 20 °C) and a specified tan δ (loss tangent) limit up to 0.20 at the 450 V rating.

Typical Applications

• General-purpose high-voltage circuits — Suited where a compact, polarized aluminum electrolytic capacitor is required at elevated voltages.
• Compact power modules — Useful in designs that need a small footprint while maintaining a 450 V rating and defined ripple handling.
• Industrial and electronic equipment — Appropriate for general-purpose use in equipment operating across –40 °C to +105 °C with requirements for 2000-hour thermal endurance.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage circuits without increasing capacitor footprint.
• Space-efficient form factor: Miniature L: 3.05 × D: 1.8 cm can package and 7.5 mm lead spacing for dense through-hole assemblies.
• Thermal reliability: Specified for –40 °C to +105 °C and endurance of 2000 hours at 105 °C under rated conditions, supporting long-term operation in elevated-temperature environments.
• Predictable ripple handling: Defined ripple current ratings at both low and high frequencies allow designers to size capacitors to meet ripple and lifetime targets.
• Measured leakage and loss specs: Leakage current formula and tan δ limits provide verifiable electrical performance for design validation and margin calculations.
