UPZ2D391MHD6

The UPZ2D391MHD6 from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPZ series, offering 390 µF capacitance at a 200 V rating. Designed as a compact, high-voltage miniature solution, it targets general-purpose power applications where a polarized electrolytic with defined ripple-handling and elevated-temperature endurance is required.

Key value propositions include a 200 V rating with a 390 µF capacitance, specified ripple-current capability at low and high frequencies, and an endurance rating of 2000 hours at 105°C—delivering predictable electrical performance in thermally demanding environments.

Key Features

• Electrical Performance — Rated capacitance of 390 µF with a tolerance of ±20% and tangent of loss angle (tan δ) 0.12 measured at 20°C, 120 Hz.
• Voltage Rating — 200 V rated voltage suitable for 200 V class circuits within the UPZ series specification.
• Ripple Current Handling — Low-frequency ripple current of 1.12 A at 120 Hz and high-frequency ripple current of 1.568 A at 10 kHz, supporting AC ripple demands within those bands.
• Leakage Current — Specified leakage current of 3220 µA (measured per product data conditions).
• Thermal and Endurance — Operating temperature range from −40°C to 105°C with an endurance rating of 2000 hours at 105°C under rated DC bias plus rated ripple current.
• Package and Mechanical — Radial can package with dimensions φ18 × 35.5 mm (3.55 × 1.8 cm), lead spacing 7.5 mm (±0.5 mm), and bulk or bag packing options (no terminal forming for bulk).
• Polarized Design — Polarized electrolytic construction for DC filtering and energy storage in polarized circuits.

Typical Applications

• General-purpose power filtering — Use in circuits requiring 390 µF at 200 V for smoothing and filtering where defined ripple and leakage specifications are needed.
• DC link / bulk smoothing — Suitable where bulk capacitance and ripple handling (1.12 A at 120 Hz, 1.568 A at 10 kHz) are required at elevated temperatures.
• 200 V system components — For assemblies designed around a 200 V rail that require a compact φ18 × 35.5 mm radial electrolytic with 7.5 mm lead spacing.
• Thermally demanding environments — Applicable where operation from −40°C to 105°C and a 2000-hour endurance at 105°C are design requirements.

Unique Advantages

• Specified high-voltage capability — 200 V rating provides clear selection criteria for 200 V-class circuits without over-specifying the component.
• Predictable ripple performance — Explicit low- and high-frequency ripple current ratings (1.12 A at 120 Hz and 1.568 A at 10 kHz) allow designers to size capacitance for real-world ripple conditions.
• Elevated-temperature endurance — 2000 hours at 105°C under rated conditions supports predictable lifetime planning in warmer operating environments.
• Compact radial form factor — φ18 × 35.5 mm can size and 7.5 mm lead spacing simplify layout and mechanical integration for through-hole assemblies.
• Available packaging options — Bulk (no terminal forming) and bag packing options accommodate different assembly and storage workflows.
• Mass-production status — Listed as in mass production, supporting volume availability and deployment.
