UHD1A392MHD6

The UHD1A392MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHD series. It delivers 3.9 mF capacitance at a 10 V rating in a compact φ16 × 20 mm can, designed for general-purpose electronic applications that require high ripple-handling and low impedance at higher frequencies.

Built for sustained operation across a wide temperature range (−40 °C to +105 °C) with a rated endurance of 5000 hours at 105 °C, this component balances compact size, high ripple current capability, and regulated electrical performance for dependable power conditioning tasks.

Key Features

• Capacitance and Voltage — 3.9 mF (3900 µF) nominal capacitance with a 10 V rated voltage and tolerance of −20% to +20% for predictable bulk energy storage.
• Low Impedance / High Ripple — Series-level design emphasizes lower impedance at high frequency; rated ripple current 2.512 A at 120 Hz and 3.14 A at 100 kHz to address demanding ripple conditions.
• Thermal and Endurance Rating — Operating temperature range of −40 °C to +105 °C with an endurance specification of 5000 hours at 105 °C under DC bias plus rated ripple current.
• Electrical Loss — Measured dissipation factor (tan δ) of 0.23 at 20 °C, 120 Hz for assessment of AC loss characteristics.
• Leakage Current — Specified leakage current of 390 µA, providing a baseline for bias and hold-up calculations.
• Compact Radial Package — φ16 × 20 mm can with 7.5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies; available in bulk or bag packing.
• RoHS Compliant — Manufactured in accordance with RoHS directives as noted for the UHD series.

Typical Applications

• General-Purpose Power Conditioning — Provides bulk capacitance and ripple handling for general-purpose circuits where low impedance and sustained ripple endurance are required.
• PCB Through-Hole Implementations — Radial lead form and 7.5 mm lead spacing make this capacitor suitable for traditional through-hole board layouts and retrofit applications.
• High-Frequency Ripple Environments — Rated high-frequency ripple current (3.14 A at 100 kHz) supports designs operating with elevated switching or high-frequency content.

Unique Advantages

• High Ripple Capacity: Rated ripple currents of 2.512 A (120 Hz) and 3.14 A (100 kHz) reduce thermal stress in high-ripple circuits, improving operating headroom.
• Low-Impedance Behavior at Frequency: Series design focus on lower impedance at high frequency supports improved filtering performance without increasing case size.
• Long Endurance at Elevated Temperature: 5000 hours rated life at 105 °C under rated conditions enables reliable performance in sustained thermal environments.
• Compact, Serviceable Form Factor: φ16 × 20 mm can and radial leads simplify placement in constrained layouts and through-hole assemblies.
• Clear Electrical Baselines: Specified tan δ (0.23 at 20 °C, 120 Hz) and leakage current (390 µA) allow straightforward loss and leakage budgeting in designs.
• Regulatory Compliance: RoHS compliance supports usage in environments requiring restricted substances conformance.
