UHD0J392MHD

The UHD0J392MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UHD series, engineered for general-purpose power applications that require high ripple handling and low impedance at higher frequencies. This 3.9 mF, 6.3 V polarized capacitor combines a compact φ12.5×25 mm can with long endurance and RoHS compliance.

Designed for circuits where bulk capacitance and sustained ripple current are required, the UHD0J392MHD delivers measurable performance across a wide operating range (−40°C to +105°C) and is supplied in bulk or bag packing for flexible assembly workflows.

Key Features

• Capacitance & Voltage: 3.9 mF (3900 µF) nominal capacitance with a rated voltage of 6.3 V and standard tolerance of −20% to +20%.
• High ripple capability: Low-frequency ripple current of 2.216 A at 120 Hz and high-frequency ripple current of 2.77 A at 100 kHz for applications with significant AC stress on the capacitor.
• Low loss (tan δ): Loss tangent specified as 0.26 when measured at 20°C, 120 Hz, supporting efficient energy handling in AC and switching environments.
• Leakage current: Low leakage current of 245.7 µA (measured after 2 minutes at 20°C under rated voltage conditions), enabling predictable bias performance.
• Long endurance: Rated for 5000 hours at 105°C, meeting extended operating-life requirements under elevated-temperature conditions.
• Package & mounting: Radial-lead, polarized aluminum can with dimensions φ12.5 × 25 mm, lead spacing 5 mm (±0.5 mm), and supplied in Bulk (No Terminal Forming) or Bag Packing.
• Temperature range & compliance: Operating range −40°C to +105°C and RoHS compliant.

Typical Applications

• Bulk power smoothing: Use as bulk capacitance on low-voltage rails where 3.9 mF and elevated ripple handling reduce voltage excursion under load.
• Switching regulator output filtering: Supports switching outputs with its low impedance and high-frequency ripple current capability to improve output stability.
• Decoupling for high-current circuits: Provides local energy storage and decoupling in circuits that experience periodic high ripple currents.

Unique Advantages

• High ripple current capacity: Rated ripple currents (2.216 A at 120 Hz and 2.77 A at 100 kHz) allow reliable operation in applications with significant AC components.
• Low high-frequency impedance: UHD series design emphasizes lower impedance at high frequency, improving AC performance in switching and decoupling scenarios.
• Compact radial can: φ12.5×25 mm package with 5 mm lead spacing delivers substantial capacitance in a small footprint for through-hole designs.
• Extended endurance at elevated temperature: 5000-hour rating at 105°C supports long-term operation under thermal stress.
• Predictable leakage and loss characteristics: Specified leakage current (245.7 µA) and tan δ (0.26 at 20°C, 120 Hz) enable accurate power-loss and bias planning.
• RoHS compliant & production-ready: Conforms to RoHS and is in mass production, with bulk and bag packing options for volume assembly.

Why Choose UHD0J392MHD?
