LKG1J103MESCAK

The LKG1J103MESCAK is a snap‑in, aluminum electrolytic capacitor from Nichicon’s LKG series, optimized for audio equipment. It delivers large bulk capacitance and power‑supply smoothing in applications where high fidelity sound reproduction is a priority.

Built for audio‑grade systems, this component combines 10,000 µF capacitance with a 63 V rating, a wide operating temperature range, and snap‑in mounting for robust board retention and straightforward assembly.

Key Features

• High Capacitance: 10,000 µF provides substantial energy storage for power supply smoothing and bulk filtering in audio power stages.
• Rated Voltage: 63 V rated voltage suitable for higher‑voltage audio amplifier rails and power subsystems.
• Audio‑Optimized Design: Part of the LKG series developed "for audio use" and designed for high‑grade audio equipment to prioritize high fidelity sound quality.
• Type‑I (Gold Tune) Grade: The part number suffix "AK" corresponds to TYPE‑I in the LKG series—described in the series documentation as a low‑profile, high‑tone quality grade.
• Performance Parameters: Tangent of loss angle (tanδ) 0.3 measured at 20°C and 120 Hz; low frequency ripple current 4.8 A at 120 Hz; specified leakage current 2,380 µA.
• Reliability and Lifespan: Endurance specified as 1,000 hours at 85°C with capacitance and leakage limits defined by the series endurance requirements.
• Mechanical and Packaging: Snap‑in radial can (φ35 × 50 mm length) for secure mounting; supplied in tray packing for handling and assembly.
• Operating Range & Compliance: Rated for −40°C to +85°C operation and RoHS compliant.

Typical Applications

• High‑Fidelity Audio Amplifiers: Bulk energy storage and supply filtering to support stable amplifier rails and minimize power‑supply ripple that can affect audio quality.
• Studio and Pro‑Audio Equipment: Power supply decoupling and reservoir capacitance for mixers, preamps, and other high‑grade audio electronics.
• Consumer Hi‑Fi Systems: Smoothing and buffering in integrated amplifiers and powered speaker submodules where sustained capacitance is required.

Unique Advantages

• Large Energy Reserve: 10,000 µF capacitance delivers measurable bulk filtering capacity to stabilize DC rails under dynamic audio loads.
• High Voltage Headroom: 63 V rating provides margin for higher‑voltage audio power supplies and reduces stress on the capacitor in elevated rail designs.
• Audio‑Centric Engineering: Designed within the LKG series specifically for audio use, prioritizing tone quality and fidelity considerations documented by the series materials.
• Robust Ripple Handling: Specified low‑frequency ripple current of 4.8 A (120 Hz) supports filtering duties in power supplies for audio amplifiers.
• Temperature Stability Information: Series data provide low‑temperature impedance characteristics (Z(−25°C)/Z(+20°C) max 4; Z(−40°C)/Z(+20°C) max 12), useful for designs operating across wide ambient ranges.
• Regulatory Compliance: RoHS compliant for use in designs requiring restricted‑substance adherence.
