UKW1C682MHD

The UKW1C682MHD is a radial lead aluminum electrolytic capacitor designed for audio and AV equipment. It delivers 6.8 mF (6800 µF) capacitance at 16 V with a ±20% tolerance and is optimized for power-supply smoothing and decoupling in audio circuits.

Key performance attributes include high ripple-current capability (2.5 A at 120 Hz, 2.875 A at 10 kHz), a rated life of 2000 hours at 85 °C, and a wide operating temperature range from −40 °C to 85 °C, providing durable performance in demanding audio environments.

Key Features

• Capacitance & Tolerance: 6800 µF nominal with ±20% tolerance at 120 Hz, 20 °C for stable bulk energy storage and smoothing.
• Rated Voltage & Polarization: 16 V rated voltage; polarized design for correct orientation in DC power rails.
• Ripple Current Handling: Low-frequency ripple current 2.5 A (120 Hz) and high-frequency ripple current 2.875 A (10 kHz) for robust filtering across audio frequency ranges.
• Loss Characteristics: tanδ (DF) = 0.3 measured at 20 °C, 120 Hz, enabling designers to assess dissipation for thermal and noise considerations.
• Leakage Current: Specified leakage current of 3264 µA for predictable standby behavior after voltage application.
• Endurance & Temperature Range: Rated for 2000 hours at 85 °C and specified to operate from −40 °C to 85 °C, supporting long-term reliability in AV systems.
• Package & Mounting: Radial lead (can) package, size φ16 × 35.5 mm (L: 3.55 × D: 1.6 cm) with 7.5 mm lead spacing for through-hole assembly and straightforward PCB layout.
• Packaging & Availability: Available in bulk (no terminal forming) / bag packing; status: mass production.
• Environmental Compliance: RoHS compliant.

Typical Applications

• Audio amplifiers: Bulk energy storage and power-rail smoothing to support stable amplifier supply rails and reduce hum and low-frequency ripple.
• AV equipment power supplies: Filtering and decoupling in receivers, preamps, and other audio/visual power modules where high capacitance and ripple handling are required.
• Speaker crossover and filtering: DC blocking and reservoir capacitance in crossover networks and active speaker electronics to maintain consistent audio performance.
• Power decoupling in audio subsystems: Local supply stabilization for DACs, op-amp stages, and power-hungry audio circuits benefiting from high capacitance in a compact radial package.

Unique Advantages

• High bulk capacitance in a compact can: 6800 µF in a φ16 × 35.5 mm package provides substantial energy storage without a large board footprint.
• Strong ripple-current capability: 2.5 A at 120 Hz and 2.875 A at 10 kHz supports both low- and high-frequency filtering needs common in audio power supplies.
• Durable thermal endurance: Rated 2000 hours at 85 °C, offering long-term stability for continuous operation in AV environments.
• Wide operating temperature range: −40 °C to 85 °C makes the part suitable for varied installation environments.
• Through-hole radial form factor: Radial lead configuration with 7.5 mm lead spacing simplifies prototyping and replacement in legacy and new designs.
• Regulatory compliance: RoHS compliant to support environmentally conscious product designs.
