Built for sustained operation, the UCP2W470MHD is specified for 10,000 hours at 105°C and supports both low‑ and high‑frequency ripple currents, delivering verifiable performance for power systems operating across −40°C to +105°C.

Key Features

• High Voltage Rating — Rated for 450 V working voltage, suitable for high‑voltage circuits requiring compact electrolytic capacitance.
• 47 µF Capacitance, ±20% Tolerance — Provides predictable energy storage with a capacitance tolerance of −20% to +20% (120 Hz, 20°C).
• Long Endurance — Rated life of 10,000 hours at 105°C under D.C. bias plus rated ripple current, with defined limits for capacitance change, tan δ and leakage after test.
• Low Loss (tan δ) — Maximum tan δ of 0.24 (measured at 20°C, 120 Hz) for stable AC loss characteristics at rated voltage.
• Ripple Current Capability — Low‑frequency ripple current 430 mA (120 Hz) and high‑frequency ripple current 645 mA (10 kHz), supporting a range of ripple environments.
• Leakage Current Specified — Measured leakage current 946 µA (after 1 minute at 20°C), enabling predictable bias current for design margins.
• Radial Lead, Compact Can — φ12.5 × 31.5 mm can with 5.0 mm lead spacing (±0.5 mm) for through‑hole mounting and straightforward board placement and soldering.
• Wide Operating Temperature — Rated for operation from −40°C to +105°C to cover common industrial and commercial temperature envelopes.

Typical Applications

• High‑voltage power supplies — Provides energy storage and smoothing at 450 V ratings where compact, long‑life capacitors are required.
• Industrial electronics — Suited for general‑purpose circuits that require durable operation across −40°C to +105°C and extended lifetime at elevated temperatures.
• DC link and filtering — Capacitance and ripple current ratings support filtering and decoupling tasks in higher‑voltage DC circuits.

Unique Advantages
