UKA1A330MDD

The UKA1A330MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UKA series, engineered for high-grade audio equipment. It is a polarized 33 µF, 10 V capacitor in a compact φ5 × 11 mm can designed for applications that demand a small footprint and stable performance across a wide temperature range.

Key value comes from its audio-focused characteristics — a measured tanδ of 0.26 (120 Hz, 20°C), defined ripple current ratings at both low and high frequencies, and endurance specified for 2000 hours at 105°C, making it suitable for demanding ambient and operating conditions found in audio systems.

Key Features

• Electrical Characteristics — 33 µF nominal capacitance with tolerance of -20% to +20% and a rated voltage of 10 V, providing defined capacitance for audio circuit designs.
• Loss Performance — Tangent of loss angle (tanδ) specified at 0.26 (measured at 20°C, 120 Hz), allowing designers to assess dissipation in audio-frequency applications.
• Ripple Current Handling — Low-frequency ripple current 58 mA (120 Hz) and high-frequency ripple current 116 mA (10 kHz) to support both power-supply and higher-frequency audio-related stress.
• Leakage Current — Leakage current specified at 9.9 µA for predictable bias behavior after voltage application.
• Robust Thermal Endurance — Rated operating range from -55°C to 105°C with endurance specified as 2000 hours at 105°C.
• Compact Radial Package — Small φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies and tight board layouts.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit manual or automated handling preferences.
• Qualification — Produced in the UKA series by Nichicon with AEC-Q200 listed in the product specifications.

Typical Applications

• High‑grade audio equipment — Suited to compact preamplifiers, headphone amplifiers and other audio products where small size and audio-oriented loss characteristics matter.
• Compact consumer audio devices — Small can and radial-lead format fit constrained board space in portable or desktop audio gear while offering defined ripple and leakage performance.
• Electronic modules with wide temperature range — Operating range of -55°C to 105°C and 2000‑hour endurance at 105°C make it appropriate for modules exposed to wide ambient conditions.

Unique Advantages

• Compact footprint: φ5 × 11 mm case size enables tight board layouts and space-constrained audio designs.
• Audio-focused electrical profile: Specified tanδ at 120 Hz and explicit ripple current ratings (120 Hz and 10 kHz) help engineers match capacitor behavior to audio-band requirements.
• Thermal endurance: 2000 hours at 105°C provides a quantifiable reliability baseline for elevated-temperature operation.
• Predictable leakage: Leakage current specification (9.9 µA) supports predictable biasing and long-term circuit behavior.
• Radial-lead convenience: 2.0 mm lead spacing and through-hole format simplify assembly and rework in prototyping and production.
• Manufacturer pedigree: Part of Nichicon’s UKA series, providing traceable design and manufacturing within an established capacitor family.
