Key attributes include a rated voltage of 80 V, a low-frequency ripple current rating of 5.4 A (120 Hz), a -40 °C to 85 °C operating range, and a 1,000-hour endurance at 85 °C—making it suitable for demanding audio power supply and energy-storage roles where stability and lifetime are important.

Key Features

• Capacitance & Tolerance — 10,000 µF nominal capacitance with ±20% tolerance at 120 Hz, 20 °C, providing substantial energy storage for power applications in audio systems.
• Voltage Rating — 80 V rated voltage suitable for higher-voltage audio power stages and DC link applications.
• Ripple Current Capability — Low-frequency ripple current rated at 5.4 A (120 Hz), enabling the capacitor to handle sustained AC ripple in power conversion and filtering circuits.
• Leakage Current — Specified leakage current of 2,680 µA (measured after rated voltage application), useful for designing steady-state bias and discharge paths.
• Endurance — Rated for 1,000 hours at 85 °C with defined limits on capacitance change, tan δ, and leakage current after the endurance test.
• Operating Temperature — Wide operating range from −40 °C to +85 °C for reliable performance across typical equipment environments.
• Mounting & Package — Lug (lag) terminal, radial can with solder lug package (φ40 × 68 mm), engineered for secure mechanical mounting in audio chassis and assemblies.
• Audio-Grade Design — Part of the LKG series developed for audio equipment with emphasis on sound quality and high-fidelity performance.
• RoHS Compliant — Meets RoHS directive requirements as specified.

Typical Applications

• High-fidelity Audio Amplifiers — Provides bulk energy storage and ripple handling for amplifier power supplies where large capacitance and an 80 V rating are required.
• Professional Audio Equipment — Suited to consoles, power amplifiers, and other professional gear that demand stable capacitance and endurance at elevated temperatures.
• Power Supply Filtering — Used in DC link and smoothing stages to reduce low-frequency ripple and support transient current demands in audio systems.

Unique Advantages

• High Capacitance at Elevated Voltage — 10,000 µF at 80 V provides significant energy density for designs needing both high capacitance and higher voltage margins.
• Designed for Audio Fidelity — LKG series focus on audio equipment means the part is specified with audio applications and sound-quality considerations in mind.
• Robust Ripple Handling — 5.4 A ripple current rating (120 Hz) supports sustained AC ripple common in power stages of audio electronics.
• Thermal and Lifetime Specification — −40 °C to +85 °C operating range and 1,000 hours endurance at 85 °C enable predictable performance under typical equipment thermal profiles.
• Secure Mechanical Mounting — Lug terminal (solder lug) radial can provides a strong, serviceable mechanical connection for chassis-mounted or panel-mounted designs.
• Regulatory Compliance — RoHS compliance supports designs targeting restricted-substance requirements.
