LKG1V103MESCBK

The LKG1V103MESCBK from Nichicon is a snap-in aluminum electrolytic capacitor in the LKG series designed for audio equipment. It provides 10,000 µF of bulk capacitance at a 35 V rating, with a snap-in radial can package and tray packing for board-level assembly.

Intended for high‑fidelity audio applications, this polarized capacitor offers a combination of large capacitance, specified low‑frequency ripple handling, and measured loss characteristics for use in audio power supply and filtering circuits. Note: this part is currently End Of Life.

Key Features

• Capacitance and Tolerance — 10,000 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), providing substantial reservoir capacity for power-supply smoothing.
• Rated Voltage — 35 V DC rated voltage suitable for common audio amplifier power rails.
• Low‑Frequency Ripple Capability — Rated low‑frequency ripple current of 3.7 A at 120 Hz to support sustained ripple handling in power-supply applications.
• Loss Tangent (tan δ) — tan δ = 0.3 specified at 20°C, 120 Hz, enabling assessment of dissipation for audio-grade filtering.
• Leakage Current — Specified leakage current of 1770 µA after standard application of rated voltage, useful for bias current budgeting.
• Endurance and Temperature Range — Designed for 1000 hours at 85°C endurance; operating temperature range –40°C to +85°C to match typical audio equipment environments.
• Package and Mounting — Radial, snap‑in can with physical size φ35 × 40 mm (L: 4 × D: 3.5 cm) for secure chassis or PCB mounting and predictable mechanical placement.
• Audio‑Focused Design — Part of the LKG series specified “For Audio Use,” developed for high‑grade audio equipment and high‑fidelity sound considerations.
• RoHS Compliance — RoHS‑compliant construction.

Typical Applications

• Audio Power Supply Smoothing — Large 10,000 µF capacitance and 3.7 A ripple rating make this capacitor suitable for reservoir and smoothing duties in audio amplifier power supplies.
• High‑Fidelity Amplifiers — Designed within the LKG audio series for use in high‑grade audio systems where bulk energy storage and low loss characteristics support sound quality goals.
• Audio Equipment Filtering — Polarized snap‑in construction and endurance at elevated temperature enable use in filter networks and decoupling stages in professional and consumer audio products.

Unique Advantages

• High Bulk Capacitance: 10,000 µF provides substantial energy reserve for low‑frequency demands and steady DC rail support in audio circuitry.
• Measured Ripple Capability: 3.7 A low‑frequency ripple current (120 Hz) helps limit voltage fluctuation under sustained load, aiding stable amplifier performance.
• Audio‑Oriented Series Design: Part of Nichicon’s LKG audio family, developed to address high‑fidelity sound requirements for HD audio equipment.
• Robust Endurance: Rated for 1000 hours at 85°C, enabling predictable performance in typical audio operating environments.
• Tray Packing for Assembly: Tray packing supports organized handling and placement for production assembly workflows.
• Regulatory Compliance: RoHS‑compliant materials help meet environmental and regulatory needs.

Why Choose LKG1V103MESCBK?

The LKG1V103MESCBK is positioned for engineers designing high‑fidelity audio equipment who require substantial bulk capacitance, rated ripple handling, and audio‑focused component selection. Its snap‑in radial package and specified endurance at 85°C make it suitable for power‑supply smoothing and filtering roles in audio amplifiers and related systems.
