UHW1V271MPD

The UHW1V271MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can. It delivers 270 µF of capacitance at a 35 V rating with polarized construction and is offered in a compact φ8 × 15 mm package.

Designed for general-purpose electronics, this part targets applications that require sustained ripple handling, low impedance across frequency, and long endurance in compact radial-lead form factors.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a rated voltage of 35 V and a capacitance tolerance of −20% to +20%.
• Low Impedance — Rated impedance of 170 mΩ supporting stable performance across the intended frequency range.
• Loss Tangent (tan δ) — tanδ of 0.11 measured at 20°C, 120 Hz, indicating controlled dissipation for the rated conditions.
• High Ripple Current — Low-frequency ripple current of 800 mA at 120 Hz and high-frequency ripple current of 1.6 A at 10 kHz; frequency coefficients for 220–560 µF series parts are provided in the datasheet for frequency-specific ripple planning.
• Long Endurance — Rated for 10,000 hours of life at 105°C under the series’ specified endurance conditions.
• Leakage Current — Specified leakage current of 94.5 µA after standard conditioning.
• Compact Radial Package — φ8 × 15 mm can with 3.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB assembly; available in bulk or bag packing.
• Operating Temperature Range — −40°C to +105°C to support a wide range of environmental conditions.
• RoHS Compliant — Conforms to RoHS directive requirements as noted for the UHW series.

Typical Applications

• General Purpose Electronics — Use where a polarized aluminum electrolytic capacitor of 270 µF / 35 V is required for power rail support or energy storage in compact assemblies.
• Power Filtering and Decoupling — Suitable for smoothing and decoupling on DC rails that require sustained ripple capability and low impedance.
• Industrial and Consumer Equipment — Applicable in designs that benefit from a small radial-lead capacitor with long endurance at elevated temperatures.

Unique Advantages

• High ripple capability: Specified ripple currents of 800 mA (120 Hz) and 1.6 A (10 kHz) provide headroom for designs with sustained AC components on the DC bus.
• Compact footprint: φ8 × 15 mm can and 3.5 mm lead spacing enable space-efficient through-hole placement without sacrificing capacitance.
• Low impedance behavior: 170 mΩ impedance and series guidance on frequency coefficients support predictable performance across frequency for power-supply designers.
• Long-term reliability: 10,000-hour endurance at 105°C supports extended service life in thermally demanding environments.
• Verified dissipation characteristics: tanδ = 0.11 at 20°C, 120 Hz helps in thermal and loss budgeting for power-dense designs.
• Regulatory compliance: RoHS compliance reduces material-conformity overhead for global deployment.
