UHW1K561MHD6

The UHW1K561MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHW series, offered in a miniature φ18 × 20 mm can. It delivers 560 µF capacitance at an 80 V rating with low impedance and high ripple-current capability.

This part is intended for general-purpose circuits where compact size, high ripple handling and long endurance are required. Its key value propositions are low high-frequency impedance, elevated ripple-current capacity, and extended lifetime at elevated temperature.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with an 80 V rated voltage and tolerance of −20% to +20%.
• High ripple-current capability — Low-frequency ripple current of 1.135 A (120 Hz) and high-frequency ripple current of 2.27 A (10 kHz), supporting demanding AC-loading conditions within ratings.
• Low impedance — Rated impedance of 140 mΩ, combined with a tan δ of 0.09 measured at 20°C, 120 Hz for stable AC performance.
• Long endurance — Designed for 12,000 hours of life at 105°C under rated voltage and specified ripple conditions.
• Wide temperature range — Operational from −40°C to +105°C to accommodate varied environmental conditions.
• Compact radial package — φ18 × 20 mm can with 7.5 mm lead spacing (±0.5 mm) and radial-lead mounting for through-hole designs.
• Leakage current — Specified leakage current of 448 µA after standard application conditions.
• Compliance & availability — RoHS compliant; available in bulk (no terminal forming) and bag packing. Status: Mass Production.

Typical Applications

• General-purpose power circuits — Used where bulk capacitance and 80 V rating are required together with substantial ripple-current capability.
• Power supply smoothing — Supports smoothing and energy buffering tasks in designs that need low impedance and sustained AC loading.
• Decoupling and bulk storage — Provides decoupling and local energy storage in systems that operate across −40°C to +105°C.

Unique Advantages

• High ripple-handling performance — Delivers measurable ripple currents (1.135 A at 120 Hz; 2.27 A at 10 kHz), reducing thermal stress in high-AC-load applications.
• Compact footprint with robust capability — φ18 × 20 mm can combines a small physical size with 560 µF capacitance at 80 V, saving board area without sacrificing performance.
• Low impedance and controlled loss — 140 mΩ impedance and tan δ of 0.09 (20°C, 120 Hz) for reliable high-frequency behavior and reduced voltage ripple.
• Extended high-temperature endurance — Rated for 12,000 hours at 105°C, supporting long-term stability in elevated-temperature environments.
• Production-ready packaging — Available in bulk and bag packing and listed as mass production, facilitating straightforward procurement and assembly planning.
