UCP2G820MHD

The UCP2G820MHD is a 400 V, 82 µF aluminum electrolytic capacitor in Nichicon’s UCP series designed for high‑voltage, miniature applications. It is a polarized, radial‑lead can engineered for general‑purpose use where compact size, high voltage rating and extended lifetime are required.

Key value propositions include a compact 12.5 × 40 mm package (D × L), a wide operating temperature range of −40 °C to +105 °C, and long life assurance with 10,000 hours endurance at 105 °C under rated conditions.

Key Features

• Capacitance & Voltage — 82 µF nominal capacitance rated at 400 V, providing energy storage and filtering capability for high‑voltage circuits.
• Long Life Endurance — Specified endurance of 10,000 hours at 105 °C with DC bias plus rated ripple current; capacitance change remains within ±20% after the test conditions.
• Wide Temperature Range — Operating temperature from −40 °C to +105 °C for reliable performance across varied environments.
• Ripple Current Capability — Rated ripple current of 620 mA at 120 Hz; frequency performance shown with a coefficient table (120 Hz = 1.00, 10 kHz or more = 1.50) to estimate ripple at other frequencies.
• Leakage Current & Dissipation — Leakage current specified by I = 0.04CV + 100 (µA) after one minute at 20 °C; tan δ (loss tangent) specified max 0.24 at 400 V for control of dielectric losses.
• Compact Radial Package — Radial can with 5.0 mm lead spacing, 12.5 mm diameter and 40 mm length (L: 4.0 cm × D: 1.25 cm) for space‑constrained boards.
• Polarized Construction — Standard polarized electrolytic design for DC filtering, smoothing and energy storage in polarized circuits.

Typical Applications

• Power Supplies — Bulk filtering and smoothing in high‑voltage power supply rails where compact, high‑voltage capacitance is required.
• DC Link and Energy Storage — Local energy storage and decoupling in high‑voltage converter stages and DC link circuits.
• Industrial Electronics — General‑purpose use in industrial control and power modules that require robust temperature and endurance performance.

Unique Advantages

• High‑Voltage Capability: 400 V rating supports higher‑voltage circuits without larger form factors.
• Miniature Footprint: 12.5 × 40 mm can delivers substantial capacitance in a compact radial package to save PCB space.
• Documented Endurance: 10,000 hours at 105 °C under rated conditions provides predictable lifetime behavior for long‑term designs.
• Frequency‑Aware Ripple Performance: Published ripple current and frequency coefficients allow designers to scale ripple ratings across frequencies for accurate thermal and reliability planning.
• Controlled Losses and Leakage: Specified tan δ and leakage current formula enable engineers to evaluate power loss and standby behavior precisely.
