UHW1K271MPD

The UHW1K271MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series, supplied in a radial-lead can. It provides 270 µF nominal capacitance at a rated voltage of 80 V with polarized construction and is intended for general-purpose electronic applications.

Designed for applications that demand high ripple-handling capability and long operational life, this part combines low impedance (180 mΩ) and high-frequency performance with a compact φ10 × 30.5 mm package and a rated operating temperature range of –40 °C to 105 °C.

Key Features

• Electrical Performance — 270 µF capacitance at 80 V rated voltage with a capacitance tolerance of −20% to +20% and polarization for DC applications.
• Low Impedance & Loss — Rated impedance of 180 mΩ and tan δ of 0.09 (measured at 20 °C, 120 Hz), supporting efficient energy transfer and reduced heating under AC ripple.
• High Ripple Current Capability — Low-frequency ripple current of 875 mA at 120 Hz and high-frequency ripple current of 1.75 A at 10 kHz, enabling use in circuits with substantial AC content.
• Long Endurance — 12,000 hours rated life at 105 °C, supporting designs that require extended operational longevity.
• Wide Temperature Range — Operates from −40 °C to 105 °C, suitable for environments with significant temperature variation.
• Compact Radial Package — φ10 × 30.5 mm can with 5 mm lead spacing (±0.5 mm), supplied bulk (no terminal forming) or bag-packed for ease of handling in through-hole assembly.
• Leakage Current — Specified leakage current of 216 µA, measured under rated conditions for predictable standby behavior.
• RoHS Compliant — Manufactured to meet RoHS requirements for material compliance.

Typical Applications

• General-purpose electronics — Serves as a compact, high-capacitance option for general-purpose designs that list “General Purpose” in application requirements.
• Power circuits with high ripple — Appropriate for circuits that require substantial ripple handling, leveraging the specified 875 mA (120 Hz) and 1.75 A (10 kHz) ripple current ratings.
• Compact high-voltage designs — Provides 270 µF at 80 V in a small φ10 × 30.5 mm radial-can footprint for space-constrained assemblies.
• Long-life electronic equipment — Suited to systems requiring extended endurance, backed by a 12,000-hour life rating at 105 °C.

Unique Advantages

• High ripple-handling in a miniature package: Combines 875 mA (120 Hz) and 1.75 A (10 kHz) ripple ratings with a φ10 × 30.5 mm can to reduce board area without sacrificing ripple performance.
• Predictable thermal and AC performance: Low impedance (180 mΩ) and tan δ of 0.09 at 120 Hz help minimize losses and heating in AC-stressed applications.
• Extended operational life: 12,000 hours at 105 °C provides design stability for products that require long-term reliability.
• Wide operating temperature window: −40 °C to 105 °C rating supports deployment across a broad set of environmental conditions.
• Through-hole radial convenience: Radial lead mounting with 5 mm lead spacing simplifies placement and soldering in through-hole assemblies and prototyping.
• RoHS compliance: Meets RoHS requirements for material composition and environmental compliance.
