UHW2A271MHD6

The UHW2A271MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon's UHW series. It is a radial-lead, polarized through-hole capacitor specified at 270 µF and 100 V, designed for general-purpose applications that require high ripple-current capability and compact size.

Key attributes include low impedance at high frequency, a broad operating temperature range from −40°C to 105°C, and an endurance rating of 12,000 hours at 105°C, delivering reliable performance in long-life designs.

Key Features

• Capacitance and Voltage — 270 µF nominal capacitance with a rated voltage of 100 V and a capacitance tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 975 mA at 120 Hz and high-frequency ripple current of 1.95 A at 10 kHz, supporting heavy AC stress conditions.
• Low Impedance and Loss — Impedance of 150 mΩ and a tan δ of 0.08 (measured at 20°C, 120 Hz) for reduced loss and improved high-frequency performance.
• Long Life / Endurance — Rated for 12,000 hours at 105°C under DC bias plus rated ripple current, supporting long-term reliability in elevated-temperature environments.
• Temperature Range — Operational from −40°C to 105°C, suitable for a wide range of ambient conditions.
• Radial Lead Package — φ16 × 20 mm can with radial leads, 7.5 mm lead spacing (±0.5 mm), and bulk/bag packing options for through-hole assembly and manual or wave insertion.
• Leakage Current — Specified leakage current of 270 µA after application of rated voltage (measured condition per product data).
• RoHS Compliant — Meets the RoHS directive requirements as indicated in the product information.

Typical Applications

• General Purpose Power Electronics — Used where compact, high-ripple current capacitors are required for power filtering and energy storage in through-hole designs.
• Industrial Equipment — Suitable for control and power modules that demand extended endurance at elevated temperatures.
• Embedded and Board-Level Designs — Fits compact layouts with a φ16 × 20 mm can and 7.5 mm lead spacing for through-hole mounting.

Unique Advantages

• High ripple-current capability: Measured ripple currents of 975 mA (120 Hz) and 1.95 A (10 kHz) reduce thermal stress and extend service life under AC loading.
• Compact, miniature can: φ16 × 20 mm size delivers high capacitance in a small footprint for space-constrained assemblies.
• Proven long-term endurance: 12,000-hour rating at 105°C provides predictable aging behavior for long-life applications.
• Low impedance and loss: 150 mΩ impedance and a tan δ of 0.08 (120 Hz, 20°C) help maintain performance across frequency range.
• Through-hole mounting convenience: Radial lead format with 7.5 mm spacing simplifies PCB layout and assembly for legacy and industrial boards.
• Regulatory compliance: RoHS compliance supports use in regulated manufacturing environments.
