LKG1J103MKN

The LKG1J103MKN is a lug/lag terminal aluminum electrolytic capacitor from Nichicon’s LKG series, specified for audio equipment and high-grade sound applications. It delivers 10,000 µF capacitance at a 63 V rating in a radial can with solder lugs for robust mechanical and electrical connections.

Designed for audio use, this part combines high bulk capacitance and a 4.9 A low-frequency ripple current rating (120 Hz) with a temperature range of −40 °C to +85 °C and a 1000 hour endurance at 85 °C, making it suitable for power smoothing and energy storage in audio power supplies and related circuits.

Key Features

• High Capacitance — 10,000 µF (10 mF) bulk capacitance for energy storage and low-frequency smoothing in audio power supplies.
• 63 V Rated Voltage — Supports higher-voltage audio and power supply rails where elevated DC headroom is required.
• Lag (Lug) Terminal, Radial Can Package — Solder lug terminals provide secure electrical connection and mechanical stability for through-hole mounting.
• Low-Frequency Ripple Handling — 4.9 A ripple current rating at 120 Hz for reliable filtering under typical audio power conditions.
• Electrical Loss and Leakage — Tangent of loss angle (tanδ) of 0.3 (measured at 20 °C, 120 Hz) and a specified leakage current of 2380 µA.
• Wide Operating Temperature and Endurance — Rated for −40 °C to +85 °C with a guaranteed endurance of 1000 hours at 85 °C.
• Tolerance and Physical Size — Capacitance tolerance −20% to +20%; physical dimensions approximately φ40 × 80 mm (L: 8 × D: 4 cm).
• RoHS Compliant — Conforms to RoHS directive as noted in product documentation.

Typical Applications

• High-Fidelity Audio Amplifiers — Bulk smoothing and reservoir capacitance to support stable supply rails and reduce low-frequency ripple in audio amplifier power stages.
• Power Supply Filtering — Large-capacitance filtering for regulated and unregulated power supplies in professional audio equipment.
• Audio System Energy Storage — Provides stored energy for transient demands in high-grade audio systems to maintain stable voltage during peaks.

Unique Advantages

• Large Bulk Capacitance: 10,000 µF provides substantial energy storage to stabilize supply rails and reduce audible power-supply modulation.
• High Voltage Headroom: 63 V rating accommodates higher DC rails used in certain audio and power applications, reducing the need for series stacking.
• Robust Mechanical Termination: Lug/solder-lug terminals offer strong, low-resistance connections suitable for through-hole mounting and serviceability.
• Designed for Audio Use: Part of the LKG series developed for high-grade audio equipment, with specifications and construction focused on sound-quality-aware applications.
• Operational Reliability: Rated for −40 °C to +85 °C with 1000 h endurance at 85 °C, supporting sustained operation in demanding ambient conditions.
• Regulatory Compliance: RoHS compliance aligns with modern environmental requirements for electronic assemblies.
