LKSH2392MESZ

The LKSH2392MESZ is an aluminum electrolytic, snap-in terminal capacitor in Nichicon's LKS series, designed for audio equipment and general-purpose applications. It provides a compact, smaller-sized option intended to improve tone quality when replacing small standard products.

This capacitor delivers 3.9 mF capacitance at a 71 V rating in a radial, can snap-in package (L: 5 × D: 2.2 cm). It is polarized, RoHS compliant, and specified for operation from −40 °C to +85 °C with defined endurance at elevated temperature.

Key Features

• Electrical — 3.9 mF capacitance with a 71 V rated voltage and a tolerance of −20% to +20%; polarized construction suitable for DC filtering and decoupling.
• Package & Mounting — Radial can with snap-in terminals for robust mechanical mounting and ease of insertion into chassis or bulkhead-style boards; listed package size L: 5 × D: 2.2 cm.
• Thermal & Lifetime — Operating temperature range from −40 °C to +85 °C and an endurance rating of 1000 hours at 85 °C, enabling predictable long-term performance under rated conditions.
• Ripple Performance — Rated low-frequency ripple current of 3.05 A at 120 Hz, supporting power-supply smoothing in audio and general-purpose circuits.
• Audio-focused Design — Specified as a smaller-sized, audio-oriented snap-in type; documented to provide an effect on tone quality when replacing small standard products.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Power supply smoothing and decoupling in amplifier and audio circuitry where replacing a smaller standard capacitor can influence tone characteristics.
• General-Purpose Electronics — Bulk filtering and energy storage in board-level power supplies and consumer electronics requiring snap-in mounting.
• Replacement / Upgrade — Direct-use as a smaller-sized upgrade or replacement for standard snap-in electrolytics to modify performance in existing designs.

Unique Advantages

• Audio-oriented specification: Marketed and specified for audio equipment with an explicit note on tone-quality improvement when replacing smaller standard parts.
• High-capacitance, mid-voltage solution: 3.9 mF at 71 V provides substantial energy storage for smoothing and decoupling in mid-voltage rails.
• Robust ripple handling: 3.05 A rated ripple current at 120 Hz supports reliable low-frequency filtering performance.
• Durable thermal performance: −40 °C to +85 °C operating range and 1000 hours endurance at 85 °C ensure stable operation over the specified lifecycle.
• RoHS compliance: Built to meet current hazardous-substance regulations for environmentally conscious designs.
