UHW1H271MPD

The UHW1H271MPD is a radial lead aluminum electrolytic capacitor from Nichicon’s UHW series, designed for miniature, high-ripple-current, high-reliability applications. It delivers 270 µF capacitance at 50 V in a compact φ10×20 mm can with 5 mm lead spacing.

Engineered for general-purpose use, this capacitor provides low impedance and elevated ripple handling across both low- and high-frequency ranges, with a wide operating temperature range of −40 °C to 105 °C and a rated endurance of 10,000 hours at 105 °C.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance with a nominal voltage of 50 V and tolerance of −20% to +20%.
• High ripple current capability — Low-frequency ripple current of 1.03 A (120 Hz) and high-frequency ripple current of 2.06 A (10 kHz) to support demanding ripple environments.
• Low impedance — Specified impedance of 90 mΩ, helping reduce voltage drop and heating in power applications.
• Reliability and lifetime — Rated for 10,000 hours at 105 °C under rated DC bias plus rated ripple current conditions.
• Temperature range — Wide operating temperature range from −40 °C to 105 °C for stable performance across environments.
• Compact radial package — φ10×20 mm metal can with 5 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing.
• Low leakage current — Specified leakage current of 135 µA, measured per the part’s conditions.
• RoHS compliant — Conforms to RoHS requirements for restricted substances.

Typical Applications

• General-purpose power electronics — Bulk energy storage and smoothing where a compact, polarized capacitor is required.
• Power supply ripple suppression — Handles both low- and high-frequency ripple currents for DC rail filtering.
• Industrial and consumer circuitry — Use in designs that demand extended lifetime at elevated temperature (10,000 h at 105 °C).

Unique Advantages

• High ripple tolerance: 1.03 A at 120 Hz and 2.06 A at 10 kHz reduce heating and improve stability in ripple-heavy circuits.
• Low-impedance performance: 90 mΩ impedance minimizes voltage drop and helps maintain regulation under load.
• Long-term thermal endurance: 10,000-hour rating at 105 °C supports robust operation in elevated-temperature environments.
• Space-efficient form factor: Compact φ10×20 mm can provides substantial capacitance in a small radial package for tight PCB layouts.
• Practical packaging options: Available in bulk (no terminal forming) or bag packing to suit assembly and handling preferences.
• Regulatory alignment: RoHS compliance supports use in designs targeting restricted-substance requirements.
