UKW1E332MHD

The UKW1E332MHD is a radial-lead aluminum electrolytic capacitor providing 3.3 mF capacitance at a 25 V rating. It is part of Nichicon’s UKW series designed for audio and AV equipment, where high bulk capacitance and stable performance are required for power smoothing and decoupling.

Key value comes from its combination of high capacitance in a compact φ16 × 25 mm can, elevated ripple-handling capability at both low and high frequencies, and a rated endurance of 2000 hours at 85°C—all in a RoHS-compliant radial package suitable for through-hole assembly.

Key Features

• Capacitance & Voltage: 3.3 mF (3300 µF) rated at 25 V for significant energy storage and supply-rail smoothing.
• High Ripple Handling: Rated ripple current of 1.95 A at 120 Hz and 2.243 A at 10 kHz supports AC ripple dissipation and reduces heating under real-world load conditions.
• Endurance: 2000 hours life at 85°C with specified recovery characteristics after test, enabling sustained operation in heated environments.
• Low-Frequency Loss (tan δ): tan δ of 0.2 measured at 20°C, 120 Hz, providing a quantified dissipation factor for circuit design considerations.
• Operating Temperature Range: Rated from –40°C to +85°C to accommodate typical AV and consumer electronics operating environments.
• Package & Mounting: Radial lead, can-style package (φ16 × 25 mm) with 7.5 mm lead spacing for straightforward through-hole mounting and mechanical stability.
• Leakage Current: Specified leakage current of 2475 µA for initial electrical budgeting and standby-power calculations.
• Compliance & Availability: RoHS compliant and listed as mass production with bulk/bag packing options (no terminal forming), supporting production procurement and assembly workflows.

Typical Applications

• Audio Power Rails: Bulk energy storage and smoothing for amplifier supply rails to stabilize voltage under dynamic audio loads.
• AV Equipment: Decoupling and reservoir capacitance in home theater receivers, amplifiers, and other consumer AV electronics.
• Power Supply Filtering: Output filtering and ripple reduction in switching supplies and linear regulators where through-hole mounting is used.

Unique Advantages

• High Bulk Capacitance in a Compact Can: 3300 µF in a φ16 × 25 mm package provides substantial energy density for space-constrained PCBs.
• Dual-Frequency Ripple Capability: Rated ripple currents quoted for both 120 Hz and 10 kHz give designers clear guidance for thermal and ripple performance across low and high-frequency applications.
• Extended Endurance at Elevated Temperature: 2000-hour rating at 85°C supports reliable operation in equipment that runs warm or is installed in confined enclosures.
• Through-Hole Mounting Simplicity: Radial-lead format with 7.5 mm lead spacing simplifies assembly and provides robust mechanical retention for consumer and pro AV builds.
• Series-Tailored for Audio: Part of the UKW series developed for audio/AV applications, aligning electrochemical performance with sound-quality-oriented designs.
• Regulatory Compliance: RoHS compliance supports use in products subject to restricted-substances requirements.
