LKG1K103MKZS

The LKG1K103MKZS is a large-can aluminum electrolytic capacitor in Nichicon’s LKG series, configured with a lug (solder lug) terminal for robust radial mounting. It provides 10,000 µF capacitance at an 80 V rating and is designed for audio equipment and high-tone-quality audio applications.

Key performance characteristics include a capacitance tolerance of ±20% (120 Hz, 20°C), a tan δ of 0.2 (measured at 20°C, 120 Hz), a low-frequency ripple current rating of 7.6 A (120 Hz), and an endurance rating of 1000 hours at 85°C. Status: End Of Life (discontinued).

Key Features

• Capacitance and Voltage: 10,000 µF (10 mF) rated capacitance with an 80 V working voltage, suitable for applications that require substantial energy storage.
• Audio-focused Design: Part of the LKG series developed for audio use and high-tone-quality requirements, targeting high-fidelity audio equipment.
• Loss Characteristics: Tangent of loss angle (tan δ) specified at 0.2 when measured at 20°C, 120 Hz, supporting predictable AC loss behavior in audio-frequency environments.
• Ripple and Leakage: Low-frequency ripple current rating of 7.6 A at 120 Hz and a specified leakage current of 2680 µA for the rated conditions.
• Endurance and Temperature Range: Rated life of 1000 hours at 85°C with an operating temperature range from −40°C to +85°C, enabling stable performance across a wide thermal span.
• Package and Mounting: Large radial can with solder lug (lag) terminal; physical size φ63 × 80 mm (diameter × length) and tray packing for board-level assembly handling.
• Environmental Compliance: RoHS compliant as indicated for the LKG series.

Typical Applications

• High-grade audio equipment: Used in designs where large bulk capacitance and audio-focused characteristics support high-fidelity power rails and signal coupling in audio systems.
• HD audio systems: Suited for audio designs that prioritize tone quality and stable performance at audio-relevant frequencies.
• Audio component assemblies: Integration into amplifier modules and other audio subassemblies where a robust lug-terminal capacitor form-factor is required.

Unique Advantages

• Large energy storage: 10,000 µF at 80 V provides significant bulk capacitance for sustaining audio power rails and smoothing supply variations.
• High ripple capability: 7.6 A low-frequency ripple current rating (120 Hz) helps manage AC ripple in audio power supplies without excessive heating.
• Audio-grade series design: Part of the LKG family designed with audio fidelity priorities, making it a fit for tone-sensitive applications.
• Wide operating temperature: −40°C to +85°C rating and 1000-hour endurance at 85°C enable reliable operation in varied thermal environments.
• Robust mounting: Lug (solder lug) terminal and radial can package provide mechanical strength for service in larger audio assemblies.
• Regulatory compliance: RoHS compliance supports use in regulated markets requiring lead-restricted components.
