UKT0J330MDD

The UKT0J330MDD is a miniature radial-leaded aluminum electrolytic capacitor designed for audio equipment. It provides a compact polarized can package with 33 µF capacitance at a 6.3 V rating, tailored for applications that require small footprint electrolytic components in audio circuits.

Engineered for reliability across a wide temperature window and with defined ripple-current capability at both low and high frequencies, this capacitor offers a practical balance of size, endurance, and electrical performance for audio-oriented power and signal designs.

Key Features

• Electrical Specification — 33 µF nominal capacitance with a 6.3 V rated voltage and ±20% tolerance, suitable for polarized circuit locations in audio equipment.
• Compact Radial Can Package — Radial, can-style package with 2 mm lead spacing and overall dimensions L: 1.1 × D: 0.5 cm, enabling space-constrained board layouts.
• Wide Temperature Range — Category operating temperature from −55°C to +105°C to support designs exposed to varied thermal environments.
• Endurance — Rated for 1000 hours at 105°C, with specified limits on capacitance change and tangent of loss angle after endurance testing.
• Ripple Current Performance — Specified ripple current: 55 mA at 120 Hz and 110 mA at 10 kHz, addressing both low- and high-frequency ripple conditions in audio power circuits.
• Leakage and Loss Characteristics — Series leakage-current limits and tan δ behavior are defined in the UKT series datasheet for predictable performance and quality control.
• Quality and Compliance — AEC-Q200 rated and RoHS compliant, supporting designs with recognized component-level qualification and environmental compliance.

Typical Applications

• Audio Equipment — Intended for use in audio devices requiring compact polarized capacitance for power filtering, decoupling, or signal circuitry where miniature can capacitors are preferred.
• Compact Electronics — Suited to small-form-factor consumer or pro-audio modules that need reliable electrolytic capacitance in a radial lead package.
• Thermally Demanding Environments — Use in assemblies that must tolerate extended operation up to 105°C thanks to the part’s defined endurance at elevated temperature.

Unique Advantages

• Space-efficient form factor: Small 1.1 × 0.5 cm can and 2 mm lead spacing reduce PCB area without sacrificing needed capacitance.
• Defined ripple handling at multiple frequencies: Specified ripple currents at 120 Hz and 10 kHz provide predictable performance for both low- and high-frequency audio power conditions.
• Wide operating temperature and proven endurance: −55°C to +105°C range and 1000-hour endurance rating at 105°C support reliable long-term operation in challenging thermal environments.
• Component qualification and compliance: AEC-Q200 rating and RoHS compliance simplify qualification and environmental acceptance for regulated designs.
• Polarized radial design: Familiar can-style, polarized construction makes integration straightforward in conventional audio PCB layouts.
