UKT0J333MRD

The UKT0J333MRD from Nichicon is a high-capacitance aluminum electrolytic capacitor in a radial-lead can designed for audio-focused power supply and smoothing applications. This polarized component delivers 33,000 µF at a 6.3 V rating with a compact φ22 × 50 mm case and 10 mm lead spacing, targeting designs that require large bulk capacitance combined with wide temperature tolerance.

Engineered for reliability in demanding environments, the part is rated for operation from −55°C to 105°C and carries AEC-Q200 recognition and RoHS compliance. Its endurance rating of 1000 hours at 105°C and specified ripple current performance make it suitable for long-run audio electronics and related power-filtering roles.

Key Features

• High Capacitance — 33,000 µF (33 mF) of bulk capacitance for energy storage, smoothing and decoupling in power rails.
• Rated Voltage — 6.3 V working voltage suitable for low-voltage audio power rails and related circuits.
• Ripple Current Performance — 2.8 A ripple current at 120 Hz (low frequency) and 3.22 A at 10 kHz (high frequency) to support dynamic load currents in audio applications.
• Wide Operating Temperature — Specified from −55°C to 105°C for use across broad environmental conditions.
• Endurance — 1000 hours life at 105°C, with capacitance and loss characteristics defined after the endurance test.
• Form Factor — Radial lead (polarized) can, size φ22 × 50 mm with 10 mm lead spacing for through-hole mounting and straightforward replacement or retrofit.
• Leakage Current — Specified leakage current of 6237 µA as provided for design verification and power-loss budgeting.
• Compliance — AEC-Q200 rating and RoHS compliance noted in product specifications.

Typical Applications

• Audio Power Supplies — Bulk energy storage and smoothing for amplifiers, preamplifiers and audio power rails to stabilize supply under varying load.
• Power Filtering — Decoupling and ripple reduction on low-voltage power buses where large capacitance and defined ripple handling are required.
• Industrial Electronics — Use in equipment requiring wide temperature operation and long endurance at elevated temperatures.

Unique Advantages

• Large Energy Reservoir: 33,000 µF provides substantial bulk capacitance to support transient loads and reduce voltage droop in audio and low-voltage power systems.
• Designed for Ripple Handling: Rated ripple currents of 2.8 A (120 Hz) and 3.22 A (10 kHz) allow designers to specify this capacitor where sustained AC content must be filtered.
• Wide Temperature Range: −55°C to 105°C operation extends applicability across harsh and variable environments.
• Qualified Durability: 1000-hour endurance at 105°C gives predictable long-term behavior for designs with elevated operating temperatures.
• Through-Hole Simplicity: Radial-lead can and 10 mm lead spacing simplify PCB integration and repair-friendly assembly.
• Standards and Compliance: AEC-Q200 recognition and RoHS compliance support regulated design requirements and supply-chain acceptance.
