UKW1H682MRD

The UKW1H682MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UKW series, engineered for audio and AV equipment. It delivers 6.8 mF (6800 µF) capacitance at a 50 V rating in a compact radial can designed for through-hole assemblies.

Designed with an audio-focused electrolyte formulation, this capacitor targets smoothing and energy-storage roles in audio power systems where large bulk capacitance, ripple handling and audible performance are important. Key attributes include a robust operating range (−40 °C to +85 °C) and a defined 2000 hour endurance at 85 °C.

Key Features

• Audio-optimized electrolyte  Developed to realize a harmonious balance of sound quality specifically for AV and audio equipment.
• High capacitance, through-hole packaging  6.8 mF (6800 µF) in a radial can (φ16 × 25 mm) for bulk energy storage and easy PCB mounting using radial leads with 10 mm lead spacing (±0.5 mm).
• Rated voltage and tolerance  50 V rated with capacitance tolerance of ±20% (measured at 120 Hz, 20 °C).
• Loss and leakage characteristics  Specified tangent of loss angle (tan δ) of 0.34 at 20 °C, 120 Hz, and a measured leakage current of 2040 µA as provided for this part.
• Ripple current capability  Designed to handle ripple current for audio supply applications — specified ripple performance includes 3.5 A at 120 Hz (low frequency) and 4.025 A at 10 kHz (high frequency) in the product specifications.
• Operating and endurance ratings  Wide operating temperature range (−40 °C to +85 °C) with an endurance rating of 2000 hours at 85 °C.
• Marking and compliance  Black sleeve with gold printed marking; RoHS compliant.

Typical Applications

• Audio power supplies  Bulk smoothing and reservoir capacitance in audio amplifiers and power stages where large capacitance and ripple handling are required.
• AV equipment  Decoupling and energy storage in consumer and professional AV systems targeted by the UKW series.
• Amplifier front-ends  Supply stabilization for preamplifiers, power amplifiers and other audio signal-chain elements where low-frequency energy reserve is needed.

Unique Advantages

• Audio-focused electrical profile: Formulated electrolyte and series characteristics tuned for AV/audio use help address audible performance considerations.
• High bulk capacitance in a compact radial can: 6.8 mF in a φ16 × 25 mm package enables significant energy storage without large PCB footprint impact.
• Through-hole mounting simplicity: Radial lead format with 10 mm lead spacing supports straightforward PCB assembly and robust mechanical connection.
• Defined endurance at elevated temperature: 2000 hours at 85 °C provides a measurable life expectancy for thermal-stressed audio power designs.
• Clear electrical data for integration: Specified tan δ, leakage current and frequency-dependent ripple current values allow designers to size and model performance precisely.
• RoHS compliant: Meets RoHS requirements for environmental compliance in electronic assemblies.
