UHW1C392MHD6

The UHW1C392MHD6 from Nichicon is a radial lead aluminum electrolytic capacitor in the UHW series, offering 3.9 mF (3900 µF) capacitance at 16 V. It combines a compact φ16 × 20 mm can with high ripple current capability and a wide operating temperature range for general-purpose power applications.

Designed for board-level radial mounting, this mass-production part provides low impedance, defined leakage and loss characteristics, and a 10,000-hour endurance rating at 105°C for reliable performance in demanding environments.

Key Features

• Capacitance & Voltage — 3900 µF nominal capacitance with a rated voltage of 16 V and a tolerance of -20% to +20% for bulk energy storage and smoothing.
• Low Impedance — Specified impedance of 45 mΩ supports stable performance under ripple conditions.
• High Ripple Current — Low-frequency ripple current 2.681 A (120 Hz) and high-frequency ripple current 3.575 A (10 kHz) to handle sustained AC stress.
• Loss & Leakage — Dissipation factor (tanδ) of 0.19 (20°C, 120 Hz) and leakage current of 624 µA for predictable electrical behavior.
• Compact Radial Package — φ16 × 20L can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for straightforward through-hole assembly.
• Wide Temperature & Long Life — Rated for operation from -40°C to +105°C with a 10,000-hour endurance at 105°C.
• RoHS Compliant — Meets RoHS environmental requirements.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling where a 16 V, 3900 µF polarized capacitor is required for board-level designs.
• High-ripple supply stages — Circuits that require higher ripple handling, leveraging the specified 2.681 A (120 Hz) and 3.575 A (10 kHz) ripple ratings.
• Energy storage for low-voltage systems — Local energy reservoir in 16 V domains using the capacitor’s 3.9 mF capacitance and low impedance.
• Temperature-challenged environments — Applications operating between -40°C and +105°C that need a long-life capacitor with a 10,000-hour rating at 105°C.

Unique Advantages

• High ripple capability: Explicit low- and high-frequency ripple current ratings enable designers to size smoothing components with confidence.
• Low impedance footprint: 45 mΩ impedance supports efficient filtering and reduced voltage ripple at the load.
• Compact radial form factor: φ16 × 20 mm can with 7.5 mm lead spacing provides a space-efficient, through-hole solution for board assemblies.
• Predictable electrical characteristics: Specified tanδ and leakage current values help ensure predictable behavior in filter and decoupling circuits.
• Long-term thermal endurance: 10,000 hours at 105°C supports designs requiring extended operational life under elevated temperature stress.
• Regulatory compliance: RoHS compliance supports environmentally conscious product designs.
