UHW1K681MHD6

The UHW1K681MHD6 is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronics. It delivers 680 µF at an 80 V rating with a compact φ16 × 25 mm case and is optimized for applications that require high ripple current handling and long-term endurance.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 80 V and a tolerance of -20% to +20% at 120 Hz, 20°C.
• High Ripple Current Capability — Low-frequency ripple current of 1.458 A (120 Hz) and high-frequency ripple current of 2.43 A (10 kHz) to support heavy AC components on DC rails.
• Low Impedance & Loss — Specified impedance of 120 mΩ and tan δ of 0.09 (measured at 20°C, 120 Hz) for improved AC performance and reduced heating under ripple stress.
• Temperature & Endurance — Operating range from -40°C to +105°C with endurance rated to 12,000 hours at 105°C under rated bias and ripple conditions.
• Mechanical & Mounting — Radial lead construction in a φ16 × 25L can with 7.5 mm lead spacing (±0.5 mm) for through-hole PCB mounting and straightforward assembly.
• Leakage & Reliability — Product-specific leakage current listed at 544 µA after standard application conditions, supporting predictable behavior in long-life designs.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing; status: mass production.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power Supply Filtering — Bulk smoothing and ripple reduction on intermediate or main DC rails where 80 V rating and high ripple capability are required.
• DC–DC Converter Output — Output filtering for higher-voltage converters benefiting from low impedance and high-frequency ripple current rating.
• Industrial Controls — Energy storage and decoupling in control electronics operating across -40°C to +105°C and requiring long endurance.
• General-Purpose Electronics — Applications needing compact, reliable aluminum electrolytic capacitance with predictable leakage and long-term stability.

Unique Advantages

• High ripple current handling: Specified ripple currents of 1.458 A (120 Hz) and 2.43 A (10 kHz) reduce the need for parallel components in high-AC-stress designs.
• Compact footprint with robust performance: φ16 × 25L packaging and 7.5 mm lead spacing provide a small can size without compromising ripple or endurance.
• Long-term reliability at elevated temperature: 12,000 hours endurance at 105°C supports designs requiring sustained performance under thermal stress.
• Predictable electrical behavior: Low impedance (120 mΩ) and measured tan δ (0.09 at 120 Hz, 20°C) help designers model AC losses and thermal rise accurately.
• Manufacturing-ready packaging: Bulk and bag packing options ease procurement for both prototyping and production runs.
• Regulatory compliance: RoHS compliance supports use in regulated markets and simplifies bill-of-materials management.
