UKT1E332MHD

The UKT1E332MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKT series designed for general audio equipment and related power applications. It delivers 3300 µF capacitance at 25 V in a compact φ12.5 × 35.5 mm can with 5 mm lead spacing and polarized radial leads.

Engineered for robust performance across a wide temperature span (−55°C to +105°C) and rated for 1000 hours endurance at 105°C, this capacitor targets audio and industrial designs that require high ripple handling and long-term reliability.

Key Features

• Capacitance & Voltage: 3300 µF nominal capacitance at a 25 V rated voltage with ±20% tolerance, suitable for bulk energy storage and smoothing in power rails.
• High Ripple Current: 1.4 A at 120 Hz (low frequency) and 1.61 A at 10 kHz (high frequency) for improved performance under AC ripple and switching environments.
• Wide Temperature Range: Operates from −55°C to +105°C, enabling use in demanding thermal environments.
• Endurance: Specified for 1000 hours at 105°C with defined limits on capacitance change, tan δ, and leakage current after endurance testing.
• Leakage Current Specification: Rated leakage current listed as 2475 µA; datasheet also defines leakage limits as 0.03CV (µA) after 1 minute and 0.01CV (µA) after 2 minutes under rated voltage at 20°C.
• Package and Mounting: Radial, can-style package (φ12.5 × 35.5 mm) with 5 mm lead spacing and bulk/bag packing for mass production assembly.
• AEC-Q200 Qualified & RoHS Compliant: AEC-Q200 qualification and RoHS compliance are specified for designs requiring recognized component-level reliability and environmental compliance.
• Tangent of Loss Angle (tan δ): For 25 V rating tan δ (max) is 0.18; for capacitances greater than 1000 µF add 0.02 for every increase of 1000 µF, per datasheet guidance.

Typical Applications

• Audio Equipment Power Supplies: Bulk filtering and smoothing in amplifier and preamp power rails to maintain stable DC rails under dynamic load.
• Audio Output Stages and Crossovers: Energy storage and decoupling where high capacitance and reliable ripple handling improve transient response.
• Industrial and Embedded Power Modules: Bulk capacitance and ripple absorption in power converters and regulator stages requiring wide temperature operation and endurance.

Unique Advantages
