LKG1C392MESACK

The LKG1C392MESACK is a snap‑in terminal aluminum electrolytic capacitor designed for audio equipment. It delivers 3.9 mF (3900 μF) nominal capacitance at a 16 V rating in a compact φ25 × 35 mm can, with a polarized snap‑in mounting intended for durable mechanical and electrical connections.

Targeted at high‑grade audio applications, this part emphasizes sound quality through a low tangent of loss angle and a design focus on high‑fidelity performance, while meeting RoHS environmental requirements.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 μF) nominal capacitance at a 16 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• Audio‑focused Design — Engineered for high‑grade audio equipment with priority on high‑fidelity sound quality and reduced loss (tan δ = 0.25 as specified).
• Snap‑in Mounting — Snap‑in terminal, radial can package for secure chassis or board mounting and robust mechanical retention.
• Ripple and Leakage — Rated low‑frequency ripple current of 2.35 A (120 Hz) and leakage current consistent with the part specification (listed at 740 μA in the product description).
• Operating Range & Reliability — Operates from −40°C to +85°C with an endurance rating of 1000 hours at 85°C (meets the series endurance criteria when restored to 20°C).
• Compact Form Factor — Size φ25 mm × 35 mm length (approx. 3.5 × 2.5 cm) provides substantial capacitance in a compact snap‑in can.
• RoHS Compliant — Manufactured in compliance with the RoHS directive noted for the LKG series.

Typical Applications

• High‑grade Audio Equipment — Use where audio fidelity is a priority; the LKG series is described specifically for high‑tone quality and HD audio requirements.
• Power Supply Reservoirs in Audio Circuits — Large capacitance and rated ripple current support energy storage roles common in audio power stages.
• Signal Chain Support — Polarized electrolytic capacitor suitable for applications within amplifier and preamplifier systems where low loss contributes to tonal performance.

Unique Advantages

• Audio‑centric tuning — The LKG series is developed with priorities for high‑fidelity sound, making this part suited to designs that emphasize tonal quality.
• High capacitance in a compact snap‑in package — 3.9 mF in a φ25 × 35 mm can reduces board space while delivering substantial energy storage.
• Measured low loss — Specified tan δ = 0.25 (measurement context provided in series data) supports reduced dissipation in audio signal supply roles.
• Robust endurance specification — Rated for 1000 hours at 85°C with defined post‑test limits for capacitance change, tan δ, and leakage current to ensure predictable ageing behavior.
• Designed for secure mounting — Snap‑in terminal and radial can construction provide reliable mechanical and electrical connection in chassis or board assemblies.
• Regulatory compliance — RoHS‑compliant construction aligns with common environmental directives.
