UHE1V392MHD

The UHE1V392MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UHE series, offering 3.9 mF capacitance at a 35 V rating in a compact φ18 × 40 mm can. It is designed for general-purpose electronic designs that require high bulk capacitance, low impedance, and extended endurance.

Key value propositions include low impedance (32 mΩ), high ripple-current capability across low and high frequencies, and a long rated lifetime of 10,000 hours at 105°C, making it suitable where sustained performance and thermal durability are required.

Key Features

• Capacitance & Voltage: 3.9 mF (3900 µF) rated at 35 V with tolerance ±20% for predictable bulk energy storage.
• Low Impedance: 32 mΩ impedance supports stable voltage behavior under load and helps reduce voltage ripple.
• High Ripple Current Handling: Low-frequency ripple current 3.424 A at 120 Hz and high-frequency ripple current 4.28 A at 10 kHz, supporting demanding AC components on DC rails.
• Long Endurance: Rated lifetime of 10,000 hours at 105°C per UHE series endurance specifications for sustained high-temperature operation.
• Loss Characteristics: tanδ of 0.16 (measured at 20°C, 120 Hz) for controlled dissipation in applications where ESR and dissipation are critical.
• Temperature Range: Operates from −40°C to +105°C to cover a wide range of environmental conditions.
• Mechanical & Packaging: Radial lead can (φ18 × 40 mm) with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing for flexible assembly workflows.
• Compliance: RoHS compliant as specified for environmental conformity.

Typical Applications

• General-purpose electronics: Bulk capacitance for boards and modules where 3.9 mF at 35 V is required for energy storage and decoupling.
• Power modules and supplies: Supports sustained ripple currents (3.424 A at 120 Hz, 4.28 A at 10 kHz) to help stabilize DC rails under load.
• Industrial equipment: Long 10,000-hour endurance at 105°C and −40°C to +105°C operating range for extended service life in thermally demanding environments.

Unique Advantages

• High bulk capacitance in a compact can: 3900 µF in a φ18 × 40 mm radial package delivers significant charge storage without excessive board footprint.
• Low impedance for better performance: 32 mΩ impedance reduces voltage drop and improves transient response in power applications.
• Robust ripple-current capability: Rated ripple currents at both low and high frequencies accommodate a variety of switching and AC conditions.
• Proven long-life endurance: 10,000-hour life at 105°C aligns with extended maintenance cycles and long-term reliability goals.
• Wide operating temperature: −40°C to +105°C supports use across a broad range of ambient conditions.
• RoHS compliant: Environmental compliance simplifies regulatory considerations for product assemblies.
