UCP2W820MHD

The UCP2W820MHD is a miniature, high‑voltage aluminum electrolytic capacitor from Nichicon’s UCP series, supplied in a radial‑lead can for through‑hole mounting. It delivers 82 µF capacitance at a 450 V rated voltage with a long endurance rating of 10,000 hours at 105 °C, targeting general‑purpose power applications that require compact high‑voltage energy storage.

Designed for reliability in elevated temperature environments, the UCP2W820MHD combines a tight mechanical footprint (φ16 × 31.5 mm / 1.6 × 3.15 cm) and industry‑standard radial lead spacing (7.5 mm) with specifications tailored for DC bus filtering and ripple handling in general‑purpose designs.

Key Features

• Capacitance & tolerance — 82 µF nominal capacitance with ±20% tolerance at 20 °C, 120 Hz.
• High rated voltage — 450 V rated voltage for high‑voltage applications within the UCP series range.
• Long endurance — Rated life of 10,000 hours at 105 °C with DC bias plus rated ripple current applied; capacitance change remains within ±20% after endurance test.
• Temperature range — Specified operating range from −40 °C to +105 °C for use across common industrial ambient conditions.
• Loss and leakage — Tangent of loss angle (tan δ) max 0.24 (measured at 20 °C, 120 Hz) and measured leakage current 1,576 µA (per product data).
• Ripple handling — Low‑frequency ripple current 640 mA at 120 Hz and high‑frequency ripple current 960 mA at 10 kHz (specified values).
• Mechanical & mounting — Radial lead can package (φ16 × 31.5 mm) with 7.5 mm lead spacing (±0.5 mm) for straightforward through‑hole assembly.
• Packaging and availability — Available in bulk (no terminal forming) or bag packing; product status: mass production.

Typical Applications

• General‑purpose power systems — Specified as “General Purpose” in the product data; suited for designs that require compact high‑voltage capacitance and long operational life.
• High‑voltage DC smoothing — 450 V rating and 82 µF capacitance address smoothing requirements where a miniature high‑voltage capacitor is needed.
• Elevated‑temperature environments — Endurance rating of 10,000 hours at 105 °C supports long‑term operation in hotter enclosures or industrial settings.

Unique Advantages

• High‑voltage capability: 450 V rating enables use in higher DC‑voltage circuits where smaller capacitors are needed.
• Compact footprint: φ16 × 31.5 mm can size (1.6 × 3.15 cm) provides a space‑efficient solution for through‑hole designs.
• Designed for long life: 10,000‑hour endurance at 105 °C reduces the need for frequent replacements in sustained high‑temperature applications.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 10 kHz help designers assess thermal and ripple handling for their frequency environments.
• Robust electrical parameters: Low tan δ (0.24 max at 120 Hz, 20 °C) and defined leakage current support predictable performance in power circuits.
• Standardized mounting: Radial lead spacing of 7.5 mm (±0.5 mm) simplifies PCB layout and assembly for through‑hole production.
