UKA0J330MDD

The UKA0J330MDD is a miniature radial lead aluminum electrolytic capacitor from Nichicon's UKA series, designed for audio equipment applications. It delivers 33 µF capacitance at a 6.3 V rating in a compact φ5 × 11 mm can with 2 mm lead spacing.

Engineered for durability across a wide temperature range (−55℃ to 105℃) and qualified to AEC‑Q200, this component targets audio designs that require a small footprint, reliable endurance, and defined electrical characteristics for low-frequency and high-frequency ripple conditions.

Key Features

• Compact Radial Can: φ5 × 11 mm size (L: 11 mm × D: 5 mm) and 2 mm lead spacing (±0.5 mm) fit tight PCB layouts and compact audio assemblies.
• Audio-focused Series: Part of the UKA series, specified for audio equipment use to meet application expectations in audio circuits.
• Electrical Rating: 33 µF capacitance with ±20% tolerance and 6.3 V rated voltage provides predictable decoupling and filtering performance.
• Low Dielectric Loss: tanδ 0.30 (max) measured at 20℃, 120 Hz, supporting low-loss operation in signal and power stages.
• Ripple Current Capability: 55 mA at 120 Hz (low frequency) and 110 mA at 10 kHz (high frequency) to handle AC stress in power and audio smoothing circuits.
• Leakage Current: Specified leakage current of 6.237 µA for predictable standby and bias behavior.
• Wide Temperature & Endurance: Operating range −55℃ to 105℃ with an endurance rating of 2000 hours at 105℃.
• Polarized, Through-Hole Mounting: Radial lead mounting type in a can package, available in bulk or bag packing for through-hole assembly processes.
• AEC‑Q200 Rated: Meets AEC‑Q200 qualification as listed in the product specifications.

Typical Applications

• Audio Signal and Power Filtering: Local decoupling and supply smoothing in preamplifiers, headphone amplifiers, and compact audio modules.
• Portable Audio Equipment: Space-constrained designs where a small radial electrolytic is needed for power rail stabilization.
• Analog Front-Ends: Supply reservoir and transient support in low-voltage analog stages where stable capacitance and low loss are required.

Unique Advantages

• Small Footprint: φ5 × 11 mm dimensions and 2 mm lead spacing enable integration into tight PCB layouts without sacrificing capacitance.
• Designed for Audio: UKA series designation and measured tanδ at audio-frequency conditions provide specification alignment for audio equipment designers.
• Defined Ripple Handling: Specified ripple current values for both low and high frequency give predictable thermal and performance margins in power-supply circuits.
• Wide Thermal Range and Endurance: −55℃ to 105℃ operating range and 2000 hours endurance at 105℃ support long-term stability in demanding environments.
• Qualification-Level Reliability: AEC‑Q200 listing provides an additional level of environmental and quality qualification as stated in the product data.
• Through-Hole Compatibility: Radial lead format and available bulk/bag packing simplify through-hole assembly and handling for production and prototyping.

Why Choose UKA0J330MDD?
