UHW1H271MPD6

The UHW1H271MPD6 is a Nichicon UHW-series aluminum electrolytic capacitor in a radial-lead package, offering 270 µF capacitance at a 50 V rating. It is a miniature, high-reliability unit designed for general-purpose electronic power applications that require compact size, high ripple handling and stable operation across a wide temperature range.

Built for applications where low impedance and sustained performance under ripple stress matter, this part combines a φ8 × 20 mm can, 3.5 mm lead spacing and a rated lifetime of 10,000 hours at 105°C.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High ripple current capability — Designed for elevated ripple: 980 mA at 120 Hz (low frequency) and 1.96 A at 10 kHz (high frequency), useful where sustained AC stress is present.
• Low impedance — Rated impedance of 120 mΩ supports effective high-frequency smoothing and decoupling; the UHW series notes lower impedance at high frequency range.
• Thermal and endurance performance — Operating temperature range −40°C to +105°C with an endurance rating of 10,000 hours at 105°C under rated bias and ripple conditions.
• Loss and leakage characteristics — Tangent of loss angle (tan δ) of 0.10 (measured at 20°C, 120 Hz) and a specified leakage current of 135 µA.
• Compact radial package — φ8 × 20 mm can, radial lead mounting with 3.5 mm lead spacing (±0.5 mm tolerance) for through-hole insertion; available in bulk or bag packing.
• RoHS compliant — Meets RoHS requirements (2011/65/EU, (EU)2015/863); product is in mass production.

Typical Applications

• Power supply decoupling and smoothing — High ripple current capability and low impedance make this capacitor suitable for output filtering in DC–DC converters and switch-mode power supplies.
• General-purpose electronic systems — Compact radial package and broad temperature range support use in industrial and consumer electronics where reliable bulk capacitance is required.
• High-frequency ripple environments — Low impedance at higher frequencies and specified ripple current at 10 kHz enable improved performance in circuits with significant high-frequency content.

Unique Advantages

• High ripple tolerance: Specified ripple currents at 120 Hz and 10 kHz (980 mA and 1.96 A respectively) reduce the need for parallel components in many designs.
• Compact footprint: φ8 × 20 mm can and radial-lead format conserve board space while providing 270 µF capacitance.
• Extended endurance at elevated temperature: 10,000 hours at 105°C supports long-term operation under thermal and electrical stress.
• Predictable loss and leakage: tan δ = 0.10 (20°C, 120 Hz) and leakage current 135 µA provide measurable parameters for design margins and reliability planning.
• RoHS compliance and availability: Conforms to RoHS directives and is listed as mass production, simplifying procurement and regulatory tracking.
