UKW1A682MHD

The UKW1A682MHD is a Nichicon UKW-series aluminum electrolytic capacitor in a radial-lead can designed for audio and AV equipment. It delivers high bulk capacitance (6.8 mF) at a low rated voltage (10 V) with a form factor suited to through‑hole mounting.

This part combines the UKW series' audio-focused electrolyte development and a compact φ16 × 25 mm package to provide high ripple handling and endurance for amplifier power rails, audio decoupling, and AV circuitry operating between −40°C and 85°C.

Key Features

• High Capacitance: 6800 µF (6.8 mF) nominal capacitance with ±20% tolerance, providing substantial bulk energy storage for smoothing and decoupling in audio power stages.
• Rated Voltage: 10 V rated voltage for low-voltage audio and AV power rails.
• Audio‑Oriented Electrolyte: Part of the UKW series developed for a harmonious balance of sound quality; optimized for AV and audio equipment.
• Loss Tangent (tan δ): tan δ = 0.34 measured at 20°C, 120 Hz, indicating the component’s specified loss characteristic under those conditions.
• Ripple Current Handling: Low-frequency ripple current 2.15 A (120 Hz) and high-frequency ripple current 2.4725 A (10 kHz), supporting sustained filtering under AC ripple loads.
• Leakage Current: Specified leakage current of 2040 µA, measured per the product specification conditions.
• Endurance: Rated life of 2000 hours at 85°C with the electrical characteristics restored at 20°C as specified by endurance tests.
• Package & Mounting: Radial lead, can-style package (φ16 × 25 mm) with 7.5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Environmental Compliance: RoHS compliant.

Typical Applications

• Audio Amplifiers: Bulk energy storage and smoothing on low‑voltage amplifier power rails to support dynamic audio signals.
• AV Equipment: Power decoupling and ripple suppression in consumer AV systems where the UKW series' audio tuning is beneficial.
• Power Filtering for Low‑Voltage Electronics: Hold-up and smoothing in 10 V power domains for modules and sub‑systems with through‑hole mounting.

Unique Advantages

• Substantial Bulk Capacitance: 6800 µF provides long-duration energy buffering and improved low-frequency smoothing compared to lower-capacitance parts.
• Measured Loss Characteristic: Specified tan δ = 0.34 at 20°C/120 Hz enables designers to account for dissipation in audio frequency applications.
• High Ripple Capability: Defined ripple current ratings at both low (2.15 A at 120 Hz) and high (2.4725 A at 10 kHz) frequencies allow predictable thermal and electrical design margins.
• Designed for Audio/AV Use: UKW-series electrolyte formulation targets a balanced sonic character, making the part appropriate for audio-focused designs.
• Through‑Hole Robustness: Radial-lead can with 7.5 mm lead spacing simplifies PCB layout and mechanical mounting for serviceable designs.
• Proven Endurance: 2000 hours at 85°C endurance rating supports deployment in equipment exposed to elevated operating temperatures.
