UCP2W270MPD

The UCP2W270MPD is a radial-lead aluminum electrolytic capacitor delivering 27 µF of capacitance at a 450 V rating in a compact φ10 × 31.5 mm can. Designed for high-voltage, miniature applications, the part pairs a long endurance specification with measurable ripple handling for reliable power-electronics performance.

With a rated operating range of –40°C to +105°C and a 10,000-hour endurance at 105°C, this capacitor is intended for general-purpose high-voltage circuitry where long life and compact size are required.

Key Features

• Capacitance & Tolerance — 27 µF nominal capacitance with a tolerance of –20% to +20% (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated at 450 V for applications requiring elevated DC voltage handling.
• Long Endurance — Specified for 10,000 hours of operation at 105°C under rated DC bias plus rated ripple current, with capacitance change within ±20% after endurance testing.
• Loss Characteristics — tan δ (loss tangent) specified at 0.24 (measured at 120 Hz, 20°C), supporting predictable dissipation behavior.
• Leakage Current — Measured leakage current of 586 µA (after 1 minute at rated voltage, 20°C), allowing designers to budget for leakage in low-current circuits.
• Ripple Current Capability — Low-frequency ripple current of 300 mA at 120 Hz and high-frequency ripple current of 450 mA at 10 kHz to support smoothing and decoupling tasks across a range of switching environments.
• Packaging & Mounting — Radial-lead, polarized can with 5.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for flexible assembly and handling.

Typical Applications

• Power Supply Filtering — Bulk and output filtering in high-voltage DC power supplies where 450 V rating and ripple handling are required.
• DC-Link and Converter Circuits — Decoupling and energy storage in compact, high-voltage inverter or converter stages benefiting from the capacitor’s miniature φ10 × 31.5 mm footprint and endurance.
• Industrial Power Electronics — General-purpose use in industrial control and power-conditioning equipment that require long life at elevated temperatures.

Unique Advantages

• Compact high-voltage solution — 450 V rating in a φ10 × 31.5 mm can provides high voltage capability in a small package footprint.
• Designed for longevity — 10,000-hour endurance at 105°C supports extended service life in thermally demanding installations.
• Predictable electrical behavior — Specified tan δ and measured leakage current enable accurate design margins for dissipation and standby currents.
• Broad ripple performance — Separate low- and high-frequency ripple ratings (300 mA at 120 Hz, 450 mA at 10 kHz) make it suitable across both mains-frequency and switching-frequency environments.
• Assembly-ready radial form — Standard radial-lead configuration with defined 5 mm lead spacing (±0.5 mm) simplifies through-hole PCB integration and mechanical placement.
