LKG1K392MESBAK

The LKG1K392MESBAK is a snap‑in terminal aluminum electrolytic capacitor engineered for high‑grade audio equipment. It pairs a high 3,900 µF capacitance with an 80 V rating and a compact φ30 × 45 mm can to support power supply smoothing and energy reservoir duties in audio designs.

Specified for continuous operation from −40 °C to +85 °C with 1,000 hours endurance at 85 °C, this RoHS‑compliant part provides measurable performance characteristics for designers who need verified ripple handling, loss tangent, and leakage figures. Status: End Of Life—verify availability before specifying.

Key Features

• High Capacitance / Voltage — 3,900 µF at 80 V provides substantial charge storage suitable for audio power supply filtering and decoupling.
• Audio‑Focused Design — Series is specifically designed for high‑grade audio equipment with emphasis on fidelity and tone quality.
• Snap‑In Mounting — Radial can, snap‑in terminal package for secure mechanical mounting and straightforward board placement.
• Ripple & Loss Characteristics — Low‑frequency ripple current rated at 3.45 A (120 Hz) and tangent of loss angle (tan δ) specified at 0.25 (20 °C, 120 Hz) for predictable AC performance.
• Leakage Current Specified — Defined leakage current of 1,670 µA for predictable bias behavior after application of rated voltage.
• Temperature & Endurance — Operates from −40 °C to +85 °C with 1,000 h life at 85 °C; endurance and shelf‑life characteristics are specified per the series datasheet.
• Packaging — Supplied in tray packing for handling and assembly efficiency.
• Environmental — RoHS compliant.

Typical Applications

• Professional audio amplifiers — Bulk energy storage and supply smoothing for power stages where high capacitance and voltage headroom are required.
• Audio power supplies — Reservoir and filter capacitor for linear and discrete power supply designs in high‑fidelity equipment.
• High‑grade consumer audio — Used in premium audio systems where the component series’ audio‑centric design supports tonal performance goals.

Unique Advantages

• Substantial energy storage: 3,900 µF at 80 V provides significant capacitance for stabilizing supply rails and reducing ripple in audio power sections.
• Defined AC performance: Rated low‑frequency ripple current (3.45 A at 120 Hz) and measured tan δ (0.25 at 20 °C, 120 Hz) give engineers concrete parameters for thermal and noise calculations.
• Robust endurance: 1,000 hours at 85 °C specified endurance supports long‑term reliability assessments for product lifecycles.
• Secure mounting: Snap‑in radial can simplifies mechanical retention and replacement in rack or chassis assemblies.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
• Tray packaging: Packaged for efficient handling and placement during production or service operations.
