UHE0J392MHD

The UHE0J392MHD is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon's UHE high-reliability series. It provides 3.9 mF of capacitance at a 6.3 V rating in a compact φ12.5 × 25 mm can for through-hole designs.

Designed for general-purpose power applications, this capacitor combines low impedance, high ripple-current capability and long life (8000 hours at 105°C) to support power smoothing, decoupling and bulk energy storage in industrial and embedded systems.

Key Features

• Capacitance and Voltage: 3.9 mF (3900 µF) rated at 6.3 V for bulk filtering and energy storage in low-voltage power rails.
• Low Impedance: Typical impedance of 89 mOhm, contributing to improved transient response and reduced voltage ripple.
• High Ripple Current Capability: Low-frequency ripple current 1.784 A (120 Hz) and high-frequency ripple current 2.23 A (10 kHz), enabling reliable handling of AC ripple across common power frequencies.
• Long Operating Life: Endurance of 8000 hours at 105°C under rated conditions, reflecting the UHE series’ high-reliability design for extended service.
• Temperature Range: Operational from −40°C to +105°C to accommodate a wide range of environmental conditions.
• Electrical Loss (tan δ): tanδ = 0.26 measured at 20°C, 120 Hz—useful for evaluating AC loss and ESR-related heating.
• Leakage Current: Specified leakage current of 245.7 µA for predictable standby and bias behavior.
• Package and Mounting: Radial-lead can, size φ12.5 × 25 mm with 5.0 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Regulatory: RoHS compliant.

Typical Applications

• Power Supply Filtering: Bulk capacitance and low impedance make this part well suited for smoothing and filtering in low-voltage DC power supplies.
• Decoupling for Embedded Systems: High ripple-current capacity and compact size support decoupling and energy buffering on compact boards and modules.
• Industrial Control Electronics: Extended 8000-hour life at 105°C and wide temperature range enable reliable operation in industrial control and automation power circuits.
• Audio and Consumer Power Rails: Large capacitance and low ESR characteristics help stabilize audio and consumer device power rails where low-voltage bulk storage is required.

Unique Advantages

• High ripple-current handling: Rated for 1.784 A at 120 Hz and 2.23 A at 10 kHz, allowing effective dissipation of AC stress in power rails.
• Compact, space-efficient can: φ12.5 × 25 mm footprint delivers 3.9 mF capacitance in a small through-hole package to save board area.
• Extended high-temperature endurance: 8000 hours at 105°C supports long-term reliability in thermally demanding installations.
• Predictable electrical performance: Low impedance (89 mOhm) and specified tanδ and leakage figures aid thermal and reliability margin calculations.
• Through-hole robustness and ease of assembly: Radial-lead package with 5.0 mm lead spacing suits traditional PCB mounting and prototyping workflows.
• Production-ready supply: Listed as mass production with bulk and bag packing options for volume assembly processes.
