UHW1K122MHD6

The UHW1K122MHD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UHW series designed for high reliability and high ripple current. It combines a 1200 µF capacitance with an 80 V rated voltage in a compact φ18 × 30.5 mm can for space-constrained power designs.

Built for general-purpose electronics that demand low impedance at higher frequencies and extended endurance, this part offers specified ripple performance at both low and high frequencies and a rated lifetime of 12,000 hours at 105°C.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance for bulk energy storage and decoupling in higher-voltage circuits.
• High Ripple Current — Low-frequency ripple current of 1.716 A (120 Hz) and high-frequency ripple current of 2.86 A (10 kHz), enabling reliable operation under AC ripple loading.
• Low Impedance / Dissipation — Rated impedance of 90 mΩ and tangent of loss angle (tan δ) of 0.09 (measured at 20°C, 120 Hz), supporting improved performance at higher frequencies.
• Long Endurance — Endurance specification of 12,000 hours at 105°C, demonstrating extended operational life under rated conditions.
• Wide Temperature Range — Operates from −40°C to +105°C to cover demanding thermal environments.
• Mechanical & Mounting — Radial lead, polarized can package with 7.5 mm lead spacing (±0.5 mm) and compact dimensions (φ18 × 30.5 mm) for through-hole assemblies.
• Leakage Current — Specified leakage current of 960 µA after standard charge conditions.
• Packaging & Compliance — Available in bulk or bag packing; RoHS compliant.

Typical Applications

• General-purpose power electronics — Bulk smoothing and energy storage in circuits that require an 80 V rated capacitor with high ripple tolerance.
• Power rails and DC link filtering — Provides low-impedance decoupling at both low and high frequencies where high ripple current handling is needed.
• Industrial and commercial equipment — Use in systems that require extended endurance at elevated temperatures (12,000 h at 105°C) and robust polarized capacitor performance.

Unique Advantages

• High ripple capability: Rated ripple currents of 1.716 A (120 Hz) and 2.86 A (10 kHz) reduce thermal stress and support stable operation under AC loading.
• Compact, miniature can: φ18 × 30.5 mm size delivers 1200 µF in a small radial package to save board space without compromising capacitance.
• Extended high-temperature life: 12,000-hour endurance at 105°C helps ensure long-term reliability in thermally demanding applications.
• Low impedance and controlled dissipation: 90 mΩ impedance and tan δ of 0.09 (120 Hz, 20°C) help maintain performance across frequency ranges.
• Polarized radial-lead format: Through-hole mounting with 7.5 mm lead spacing simplifies assembly and mechanical stability for rugged installations.
• RoHS compliant packaging: Available in bulk or bag packing and compliant with RoHS requirements for regulatory compatibility.
