UHW1C392MHD

The UHW1C392MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic equipment. It delivers 3,900 µF capacitance at a 16 V rating with a compact φ12.5 × 30.5 mm case and 5.0 mm lead spacing.

Engineered for applications requiring high ripple handling and low impedance at higher frequencies, this UHW series part combines high ripple current performance with a long endurance rating (10,000 hours at 105°C) and RoHS compliance.

Key Features

• Capacitance & Voltage — 3,900 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 2.846 A (120 Hz) and high-frequency ripple current of 3.795 A (10 kHz), suitable for demanding ripple environments.
• Low Impedance — Rated impedance of 36 mΩ supports lower losses and improved filtering performance at higher frequencies.
• Thermal and Endurance Performance — Operating temperature range −40°C to +105°C with a rated life/endurance of 10,000 hours at 105°C.
• Electrical Losses — Dissipation factor (tanδ) specified at 0.19 (measured at 20°C, 120 Hz), and leakage current of 624 µA.
• Compact Radial Package — φ12.5 × 30.5 mm can, radial-lead mounting, 5.0 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Compliance & Availability — RoHS compliant and listed as mass production status in the Nichicon UHW series.

Typical Applications

• Power supply filtering — Bulk energy storage and smoothing of DC rails where high ripple currents and low impedance are required.
• High-frequency decoupling — Reduction of high-frequency noise and ripple owing to the capacitor’s lower impedance at higher frequencies.
• General-purpose electronic equipment — Use in compact, reliable power subsystems across a variety of electronic designs that require long endurance at elevated temperatures.

Unique Advantages

• High ripple capability: 3.795 A at 10 kHz and 2.846 A at 120 Hz provide margin for circuits with significant AC content on DC rails.
• Compact form factor: φ12.5 × 30.5 mm can and radial leads deliver a small footprint for space-constrained board designs.
• Low loss and low impedance: 36 mΩ impedance reduces voltage drop and heat dissipation under load, improving power delivery efficiency.
• Long-term reliability: 10,000-hour endurance at 105°C supports sustained operation in higher-temperature environments.
• Easy integration: Standard radial-lead package and 5.0 mm lead spacing simplify through-hole mounting and assembly processes.
• Regulatory compliance: RoHS compliance aligns with environmental requirements for commercial electronic products.
