UKT0J332MHD

The UKT0J332MHD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon’s UKT series, designed for use in audio equipment. It delivers high bulk capacitance in a compact φ12.5 × 20 mm can for power smoothing and decoupling in audio electronics.

Key value comes from a wide operating temperature range of -55°C to 105°C, a 1000-hour endurance rating at 105°C, and ripple current capability suited to both low- and high-frequency power conditions.

Key Features

• Capacitance & Tolerance — 3300 µF nominal capacitance with tolerance of -20% to +20% (measured at 120 Hz, 20°C), providing substantial energy storage for audio power rails.
• Rated Voltage & Polarization — 6.3 V rated, polarized aluminum electrolytic design for through-hole radial-lead mounting.
• Temperature Range & Endurance — Operating temperature -55°C to 105°C with a lifetime/endurance of 1000 hours at 105°C.
• Ripple Current Performance — Low-frequency ripple current 910 mA (at 120 Hz) and high-frequency ripple current 1.0465 A (at 10 kHz), supporting both mains-frequency and higher-frequency switching environments.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) 0.34 (measured at 20°C, 120 Hz) and leakage current 623.7 µA, enabling predictable loss and standby characteristics.
• Package & Mounting — Radial lead, can package sized φ12.5 × 20 mm with 5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing.
• Compliance & Qualification — RoHS compliant and AEC-Q200 qualified.
• Product Status — End Of Life.

Typical Applications

• Audio Equipment — Energy storage and power-supply smoothing in amplifiers and audio signal chains where sustained bulk capacitance is required.
• Power Filtering for Audio Electronics — Decoupling and ripple attenuation for low-voltage audio power rails to support stable operation of analog stages.
• Through-Hole Designs — Direct fit for PCB designs that use radial-lead mounting and require compact, high-capacitance solutions.

Unique Advantages

• High Bulk Capacitance in a Compact Can — 3300 µF in a φ12.5 × 20 mm case delivers significant energy density for space-constrained audio boards.
• Extended Temperature Performance — Rated from -55°C to 105°C with 1000 hours endurance at 105°C, supporting reliability in demanding thermal environments.
• Broad Ripple Handling — Specified ripple current at 120 Hz and 10 kHz provides predictable behavior across low- and high-frequency power conditions common in audio power supplies.
• Controlled Loss and Leakage — Defined tan δ and leakage current figures allow accurate budgeting for dissipation and idle current in designs.
• Industry Compliance — RoHS compliance and AEC-Q200 qualification help when conformity to recognized standards is required.
• Through-Hole Simplicity — Radial lead can form factor simplifies assembly and prototyping on traditional PCBs.
