LKSH2392MESA

The LKSH2392MESA is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, optimized for audio equipment and general-purpose applications. It delivers 3.9 mF capacitance at a 71 V rating in a compact radial can snap-in package designed for improved tonal performance when replacing smaller standard parts.

Key attributes include snap-in mounting for board retention, RoHS compliance, and electrical and thermal specifications targeted at reliable performance across common consumer and pro-audio environments.

Key Features

• Electrical Performance — 3.9 mF capacitance with a rated voltage of 71 V and polarization; capacitance tolerance is ±20% at 120 Hz, 20°C.
• Ripple Handling — Rated ripple current of 3.05 A at 120 Hz suitable for smoothing and filtering tasks in power sections.
• Package & Mounting — Radial can, snap-in terminal package for secure board mounting; physical size approximately L: 4 × D: 2.5 cm for compact designs.
• Temperature & Lifetime — Operates from -40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C.
• Audio-Focused Design — LKS series smaller-sized construction intended for audio equipment; replacing small standard parts can yield a perceived tone-quality improvement.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• Audio Equipment — Power supply smoothing and decoupling in audio amplifiers and audio circuits where tonal characteristics and compact size matter.
• General-Purpose Power Filtering — Bulk capacitance and ripple filtering in consumer and industrial power supplies that accept polarized electrolytic capacitors.
• Amplifier and Signal Chain Support — Use in DC link and decoupling roles within amplifier power sections to support stable performance under load.

Unique Advantages

• Audio-tuned Form Factor: Smaller-sized LKS construction intended to improve perceived tone when used as a replacement for small standard capacitors.
• High Ripple Capability: 3.05 A ripple rating at 120 Hz enables robust smoothing in demanding power sections.
• Compact Snap-in Packaging: Radial, snap-in can design provides board retention and a small footprint (L: 4 × D: 2.5 cm) for space-constrained layouts.
• Wide Operating Range: Rated for -40 °C to +85 °C operation with a 1000-hour endurance at 85 °C for predictable lifetime behavior under elevated temperature stress.
• Regulatory Compliance: RoHS compliance supports use in designs that require restricted-substance conformity.
