UKL0J682KHD

The UKL0J682KHD is a radial-lead miniature aluminum electrolytic capacitor in Nichicon’s UKL series, designed for low leakage and high-capacitance requirements. It delivers 6800 µF of capacitance at a nominal 6.3 V rating in a compact φ18 × 35.5 mm can with polarized radial leads.

Engineered for audio applications, this capacitor combines high capacitance, substantial ripple-handling capability and a long endurance rating (2000 hours at 85°C) to support power-smoothing and decoupling duties in audio power supplies and related circuitry.

Key Features

• High Capacitance (6.8 mF)  Provides large energy storage for smoothing and reservoir functions in low-voltage audio power rails.
• Rated Voltage 6.3 V  Specified for low-voltage applications where bulk capacitance is required.
• Low Leakage Current  Specified leakage current of 85.68 µA supports stable biasing and minimizes standby losses.
• Robust Ripple Performance  Low-frequency ripple current 1.76 A (120 Hz) and high-frequency ripple current 2.024 A (100 kHz) enable effective AC ripple handling across a wide frequency range.
• Endurance and Temperature Range  Rated for 2000 hours at 85°C and an operating temperature range of –40°C to +85°C, supporting sustained operation in common electronic environments.
• Radial Lead, Compact Can Package  φ18 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB placement.
• Capacitance Tolerance and Loss Angle  Capacitance tolerance −10% to +10% and measured tan δ (DF) of 0.31 at 20°C, 120 Hz for predictable electrical behavior.
• RoHS Compliant  Meets RoHS requirements for restricted substances.

Typical Applications

• Audio Power Supplies  Bulk smoothing and reservoir capacitance for amplifier and preamplifier power rails, leveraging the 6800 µF capacity and high ripple current ratings.
• Consumer and Pro Audio Equipment  Supports stable DC supply filtering in compact amplification modules and audio electronics where polarized, high-value capacitance is required.
• Compact/Portable Audio Devices  Offers large energy storage in a miniature radial can (φ18 × 35.5 mm) for space-constrained designs that demand reliable audio power decoupling.

Unique Advantages

• Large Bulk Capacitance in a Small Footprint: Enables effective energy storage and smoothing without excessive board area thanks to the 6800 µF value in a φ18 × 35.5 mm can.
• High Ripple Handling Across Frequencies: Rated ripple currents of 1.76 A (120 Hz) and 2.024 A (100 kHz) provide designers quantifiable performance for both low- and high-frequency ripple scenarios.
• Low Standby Losses: The low leakage current specification (85.68 µA) helps maintain bias stability and reduces quiescent drain in audio systems.
• Designed for Sustained Operation: Endurance rating of 2000 hours at 85°C and an operating range of −40°C to +85°C align with long-term, continuous-use audio applications.
• Through-Hole, Radial Mounting: The radial lead format with 7.5 mm lead spacing simplifies assembly and prototyping for traditional PCB layouts.
• Regulatory Compliance: RoHS compliance supports use in assemblies that must meet restricted-substance requirements.
