LKG1C183MESBBK

The Nichicon LKG1C183MESBBK is an aluminum electrolytic, snap‑in terminal capacitor in the LKG series engineered for audio equipment. It delivers large bulk capacitance and board‑mount secure snap‑in installation for high‑grade audio and related power filtering applications.

Key differentiators include 18,000 µF capacitance at 16 V, a 1000‑hour endurance rating at 85°C, and a snap‑in radial can package sized φ30 × 40 mm (L: 4 cm × D: 3 cm), providing a compact high‑capacitance solution for audio power rails and smoothing tasks.

Key Features

• High Bulk Capacitance — 18,000 µF nominal capacitance (±20%) suited for bulk energy storage and smoothing of power rails in audio equipment.
• Rated Voltage — 16 V rated voltage appropriate for low‑voltage audio amplifier power supplies and DC bus decoupling.
• Snap‑In Radial Can Package — Snap‑in terminal (radial, can‑snap‑in) mounting for secure PCB retention and simplified assembly in chassis or board‑mounted applications.
• Ripple Current Capability — 3.4 A ripple current rating at 120 Hz to support dynamic load currents common in audio power stages.
• Loss Angle (tan δ) — Specified tan δ of 0.35 (measured at 120 Hz, 20°C), useful for assessing ESR‑related effects in audio circuits.
• Leakage Current — Specified leakage current of 1600 µA, enabling predictable standby and bias conditions in sensitive audio circuitry.
• Temperature and Endurance — Operating range −40°C to +85°C with 1000 hours endurance at 85°C; post‑test limits preserve capacitance within ±20% and leakage at or below initial specified values.
• Audio‑Focused Design — Part of the Nichicon LKG series developed for high‑fidelity audio equipment, prioritizing tone quality and stable performance in audio systems.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.
• Identification — Marked with gold‑color lettering on a black sleeve for rapid visual identification.

Typical Applications

• High‑Grade Audio Amplifiers — Bulk filtering and supply smoothing on amplifier power rails to support steady voltage under dynamic audio loads.
• Professional Audio Equipment — Energy storage and decoupling in mixers, preamps, and studio hardware where large capacitance and endurance are required.
• Audio Power Supplies — Reservoir and smoothing capacitor in low‑voltage DC supplies for consumer and pro audio systems.

Unique Advantages

• Large Capacitance in a Compact Can — 18,000 µF in a φ30 × 40 mm package provides substantial energy storage without excessive board area.
• Secure Snap‑In Mounting — Snap‑in terminals deliver reliable mechanical retention for chassis and PCB installations in equipment subject to handling or vibration.
• Designed for Audio Fidelity — LKG series heritage targets high‑tone quality, making this part suitable where audio performance is a design priority.
• Robust Thermal Endurance — 1000‑hour rating at 85°C with defined post‑test limits supports reliable operation in warm environments.
• Measurable Ripple and Loss Characteristics — Published ripple current (3.4 A at 120 Hz) and tan δ (0.35 at 120 Hz, 20°C) allow designers to model thermal and ESR behavior accurately.
• Regulatory Compliance — RoHS compliance simplifies selection for markets requiring restricted‑substance conformity.
