UKW1A331MED

The UKW1A331MED is a radial-lead aluminum electrolytic capacitor from Nichicon’s UKW series, specified at 330 µF and 10 V. It is a polarized, radial-can capacitor designed for audio and AV equipment where compact size and audio-oriented performance are required.

Key value comes from its audio-focused electrolyte development, compact φ6.3 × 11 mm can, defined electrical characteristics (tan δ, leakage, ripple current) and a 2000-hour endurance rating at 85°C for reliable service in consumer and AV designs.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance at a 10 V rated voltage with ±20% tolerance, suitable for decoupling and smoothing in low-voltage audio circuits.
• Audio-Optimized Electrolyte — Series-level design emphasis on a new electrolyte formulation targeted at a harmonious balance of sound quality, making it suited for AV and audio applications.
• Loss & Leakage — Specified tan δ (loss tangent) of 0.24 maximum at 20°C, 120 Hz for the 10 V rating and a measured leakage current of 99 µA, giving predictable loss and leakage behavior for circuit design.
• Ripple Current Capability — 270 mA at 120 Hz (low frequency) and 405 mA at 10 kHz (high frequency) ripple current ratings, supporting dynamic audio load conditions and power smoothing.
• Endurance — 2000 hours life at 85°C with defined limits: capacitance change within ±20%, tan δ ≤ 200% of initial spec, and leakage current no greater than initial specified value after test conditions.
• Mechanical & Mounting — Radial lead mounting in a φ6.3 × 11 mm can with 2.5 mm lead spacing; packaged in bulk (no terminal forming) / bag packing for straightforward through-hole assembly.
• Operating Range & Compliance — Rated for operation from −40°C to +85°C and compliant to RoHS directives.

Typical Applications

• Audio Amplifiers and Preamps — Used for power supply smoothing and decoupling where audio-focused electrolyte characteristics help maintain tonal balance and stability.
• AV Equipment — Suited to consumer audio/video devices that require compact electrolytic capacitors with defined ripple handling and endurance at elevated temperatures.
• Power Filtering for Low-Voltage Boards — Provides bulk capacitance and ripple current capacity for 10 V rails in small form-factor PCBs using radial through-hole components.

Unique Advantages

• Audio-Centric Formulation: Electrolyte development aimed at a harmonious balance of sound quality, directly addressing AV and audio design priorities.
• Predictable Electrical Behavior: Specified tan δ and leakage figures give designers measurable parameters for loss and bias leakage in low-voltage circuits.
• Compact Radial Can: φ6.3 × 11 mm package and 2.5 mm lead spacing deliver a small footprint for through-hole layouts without sacrificing capacitance.
• Robust Ripple Handling: Defined ripple current ratings at both 120 Hz and 10 kHz support varying audio power and switching environments.
• Long Endurance at Elevated Temperature: 2000 hours at 85°C endurance rating with clear post-test acceptance criteria for capacitance, tan δ and leakage.
• RoHS Compliant: Conforms to RoHS requirements, simplifying compliance considerations for end products.
