UHE1C392MHD

The UHE1C392MHD is a Nichicon UHE-series aluminum electrolytic capacitor in a miniature radial-lead can. It provides 3900 µF (3.9 mF) capacitance at a 16 V rating with low impedance and radial lead mounting for through-hole designs. As part of the UHE series it targets general-purpose electronic applications requiring high ripple handling, long endurance, and operation across a wide temperature range.

Key Features

• Capacitance and Voltage — 3900 µF nominal capacitance with a rated voltage of 16 V and a capacitance tolerance of −20% to +20%.
• Low Impedance — Rated impedance 56 mΩ, supporting low-loss energy storage and filtering in power rails.
• High Ripple Current — Low-frequency ripple current 2.68 A (120 Hz) and high-frequency ripple current 3.35 A (10 kHz), suitable for smoothing and decoupling under dynamic load.
• Long Endurance — Life rating of 10000 hours at 105°C as provided for the UHE series, supporting extended operation at elevated temperature.
• Leakage and Loss Characteristics — Specified leakage current of 624 µA and tangent of loss angle (tan δ) 0.2 measured at 20°C, 120 Hz.
• Mechanical and Mounting — Radial lead can package with a diameter of 12.5 mm and length 40 mm (φ12.5 × 40L), lead spacing 5.0 mm with ±0.5 mm tolerance, designed for through-hole assembly.
• Wide Operating Temperature — Rated for operation from −40°C to +105°C.
• RoHS Compliant — Manufactured in compliance with RoHS directives as specified for the UHE series.

Typical Applications

• Power-supply smoothing — 3.9 mF at 16 V and low impedance make this capacitor suitable for bulk smoothing on low-voltage power rails.
• Decoupling and hold-up — High ripple-current capability supports decoupling and transient energy delivery in embedded systems and control electronics.
• General-purpose electronics — Radial-lead can and compact φ12.5×40 mm size fit a variety of through-hole boards and assemblies where robust, long-life capacitance is required.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both low and high frequencies (2.68 A at 120 Hz, 3.35 A at 10 kHz) enable reliable filtering across a range of switching and line conditions.
• Low ESR/Impedance: 56 mΩ impedance reduces voltage drop and heat under load, improving efficiency in power-conditioning circuits.
• Extended endurance: 10000-hour life at 105°C supports long-term operation in elevated-temperature environments.
• Compact radial package: φ12.5 × 40 mm can with 5.0 mm lead spacing provides a space-efficient through-hole solution for engineers retaining serviceability and mechanical robustness.
• Measured loss and leakage data: Specified tan δ (0.2 at 20°C, 120 Hz) and leakage current (624 µA) allow predictable thermal and leakage budgeting in designs.
• Regulatory compliance: RoHS-compliant construction supports restricted-substance requirements.
