UHW1E392MHD

The UHW1E392MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHW series, designed for high ripple current and high-reliability applications. It delivers 3.9 mF (3900 µF) at 25 V in a compact φ16 × 25 mm can with 7.5 mm lead spacing.

Engineered for general-purpose electronic designs that require low impedance at higher frequencies and robust thermal endurance, this radial-lead, polarized capacitor offers a combination of high capacitance, significant ripple handling, and a long rated life at elevated temperature.

Key Features

• Capacitance & Voltage  3.9 mF (3900 µF) nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20%.
• Low Impedance  Impedance specified at 39 mΩ, supporting lower AC voltage drop in decoupling and filtering applications.
• High Ripple Current  Rated low-frequency ripple current of 2.8575 A at 120 Hz and high-frequency ripple current of 3.81 A at 10 kHz for demanding power conditions.
• Thermal Endurance  Rated operating temperature range −40°C to +105°C with a guaranteed lifetime of 10,000 hours at 105°C.
• Loss & Leakage Characteristics  tan δ of 0.17 (measured at 20°C, 120 Hz) and a specified leakage current of 975 µA.
• Package & Mounting  Radial lead, polarized can (φ16 × 25L) with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Compliance  RoHS compliant as specified for the UHW series.

Typical Applications

• General-purpose power filtering  Bulk capacitance and low impedance make the UHW1E392MHD suitable for smoothing and decoupling in power supply circuits that require 3.9 mF at 25 V.
• High ripple environments  Use where elevated ripple currents occur — the part is rated for 2.8575 A (120 Hz) and 3.81 A (10 kHz), supporting higher AC stress conditions.
• Temperature-challenged deployments  Applications that require operation across −40°C to +105°C benefit from the capacitor’s extended temperature range and 10,000-hour life at 105°C.

Unique Advantages

• Compact, high-capacitance footprint: 3.9 mF in a φ16 × 25 mm can minimizes PCB area for a large capacitance value.
• Low impedance for improved high-frequency performance: 39 mΩ impedance reduces voltage ripple and improves transient response where low AC resistance matters.
• High ripple capability: Rated ripple currents at both low and high frequencies support designs with significant AC stress.
• Robust thermal endurance: −40°C to +105°C operating range with 10,000 hours life at 105°C provides predictable long-term performance under elevated temperatures.
• Through-hole radial-lead form: Polarized radial-lead package simplifies assembly for through-hole designs and replacement applications.
• Regulatory compliance: RoHS-compliant construction aligns with environmental requirements.
