LKSN2392MESZ

The LKSN2392MESZ is a snap‑in, radial aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general‑purpose electronic applications. It provides a compact, polarized can package optimized for replacement upgrades from smaller standard parts to help improve tone quality in audio designs.

Key attributes include a 3.9 mF capacitance at 56 V, snap‑in mounting for secure board installation, RoHS compliance, and electrical characteristics specified at 120 Hz and 20 °C.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 µF) rated at 56 V, with capacitance tolerance of ±20%.
• Snap‑in Radial Can Package — Snap‑in mounting and radial can construction provide a secure, serviceable installation for chassis or PCB assemblies.
• Audio‑Focused Design — Specified in the LKS series as a smaller size intended to improve tone quality when used as a replacement for small standard parts in audio equipment.
• Operating Range — Rated for operation from −40 °C to +85 °C, with endurance verified for 1000 hours at 85 °C.
• Ripple Handling — Rated ripple current of 2.6 A at 120 Hz, supporting power‑supply smoothing and decoupling duties in audio and general electronics.
• Leakage Current Specification — After 5 minutes’ application of rated voltage at 20 °C, leakage current is specified as not more than 3√(C·V) µA (C in µF, V in V), per the LKS series datasheet.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Footprint — Physical size approximately L: 4.0 cm × D: 2.2 cm, suitable for space‑constrained assemblies.

Typical Applications

• Audio Equipment — Use on amplifier power rails and audio circuits where replacement with a smaller, audio‑optimized electrolytic can improve perceived tone quality.
• Power Supply Smoothing — Bulk smoothing and decoupling in general‑purpose electronic power supplies operating up to 56 V.
• Replacement/Upgrades — Direct replacements for small standard snap‑in capacitors to achieve improved audio performance in consumer and professional equipment.

Unique Advantages

• Audio‑oriented performance: LKS series design intent for improved tone quality makes this part suited for audio upgrade and signal‑sensitive circuits.
• High ripple capability: 2.6 A ripple current rating at 120 Hz supports demanding smoothing tasks without excessive heating under specified conditions.
• Durable temperature endurance: 1000 hours at 85 °C endurance provides predictable long‑term behavior in elevated‑temperature environments within the rated range.
• Compact snap‑in package: Radial snap‑in can permits secure mounting in compact enclosures while simplifying replacement and assembly.
• Measured leakage specification: Leakage current defined by 3√(C·V) µA after 5 minutes at 20 °C gives a clear, testable criterion for insulation performance.
• RoHS compliance: Conforms to current RoHS directives, supporting regulatory requirements for lead‑restricted assemblies.
