LKG2A392MESCAK

The LKG2A392MESCAK is an aluminum electrolytic capacitor in a snap‑in terminal package, optimized for high‑grade audio equipment. It combines high capacitance and a 100 V rating with electrical characteristics specified for audio applications.

Designed for power‑supply smoothing and low‑frequency filtering, this snap‑in can delivers 3.9 mF of bulk capacitance with specified ripple current and dissipation characteristics to support reliable operation within audio systems.

Key Features

• Capacitance & Voltage — Nominal 3.9 mF (3900 µF) capacitance with a 100 V rated voltage.
• Low‑frequency Ripple Current — Rated for 4.3 A ripple current at 120 Hz, supporting sustained low‑frequency loading.
• Dissipation Factor (tan δ) — Specified tan δ of 0.25 measured at 20°C, 120 Hz, for predictable loss behavior in audio circuits.
• Leakage Current — Specified leakage current of 1870 µA.
• Endurance & Temperature — 1000 hours at 85°C rated life; operating temperature range −40°C to +85°C.
• Mechanical & Mounting — Snap‑in terminal, radial can package, physical size φ35 × 40 mm, supplied in tray packing for board‑level assembly.
• Tolerance & Polarity — Capacitance tolerance ±20%; polarized construction.
• RoHS Compliant — Meets the RoHS directive requirements indicated in the product data.

Typical Applications

• High‑Fidelity Audio Amplifiers — Bulk filtering and reservoir capacitance for power rails in audio amplifier power supplies.
• Professional Audio Equipment — Power smoothing and decoupling in studio or broadcast audio systems where high capacitance and reliable ripple handling are required.
• Audio Power Supplies — Low‑frequency filter sections and energy storage for regulated and unregulated audio power modules.

Unique Advantages

• High‑Voltage Bulk Storage: 100 V rating combined with 3.9 mF capacitance provides substantial energy storage for higher‑rail audio designs.
• Robust Low‑Frequency Performance: 4.3 A ripple current rating at 120 Hz reduces heating and supports stable operation under audio load conditions.
• Measured Dissipation Characteristics: tan δ specified at 0.25 (20°C, 120 Hz) gives predictable loss performance for design margin calculations.
• Engineered for Audio: Part of the LKG series developed for high‑grade audio equipment, aligning materials and terminal configuration to audio‑centric requirements.
• Durability at Elevated Temperature: 1000 h endurance at 85°C with post‑test limits on capacitance change, tan δ, and leakage current per the series specifications.
• Assembly‑Friendly Package: Snap‑in radial can and tray packing simplify board mounting and handling during production.
