Overview of LKSN2392MESA – Snap-in Aluminum Electrolytic Capacitor, 56 V, 3900 µF

The LKSN2392MESA is a smaller-sized, snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose power applications. It provides 3.9 mF capacitance at a 56 V rating in a compact radial can (φ25 × 35 mm) with snap-in mounting for secure installation.

Key electrical characteristics include a low-frequency ripple capacity of 2.6 A (120 Hz), a dissipation factor (tanδ) of 0.3 measured at 20°C and 120 Hz, and a rated operating temperature range of −40°C to +85°C with 1000 hours endurance at 85°C.

Key Features

  • Snap-in radial can package — Snap-in mounting and radial can construction provide robust mechanical retention for chassis or PCB mounting.
  • Audio-focused, smaller-sized design — Specified “for audio equipment” and noted as a smaller-sized LKS series part intended to improve tone quality when replacing small standard products.
  • Capacitance and voltage — 3.9 mF (3900 µF) capacitance with a 56 V rated voltage and tolerance of −20% to +20%.
  • Ripple handling — Low-frequency ripple current rating of 2.6 A at 120 Hz for smoothing and reservoir duties in power supplies.
  • Electrical loss and leakage — Dissipation factor (tanδ) 0.3 (measured at 20°C, 120 Hz) and a specified leakage current of 1400 µA.
  • Temperature and endurance — Operating range −40°C to +85°C with endurance specified as 1000 hours at 85°C.
  • RoHS compliant — Meets RoHS directive requirements as stated for the LKS series.

Typical Applications

  • Audio equipment — Energy reservoir and smoothing capacitor in audio power supplies where the part’s audio-focused design and compact size are desired.
  • General-purpose power filtering — Bulk capacitance for DC bus smoothing or power supply decoupling in equipment requiring 56 V ratings.
  • Moderate ripple environments — Circuits with low-frequency ripple up to 2.6 A (120 Hz) where reliable ripple handling and endurance are required.

Unique Advantages

  • Compact high-capacitance footprint — 3.9 mF in a φ25 × 35 mm package (L: 3.5 × D: 2.5 cm) conserves board or chassis space while delivering substantial bulk capacitance.
  • Designed for audio tone quality — LKS series specification notes improved tone quality versus small standard products, making it suitable for audio-focused replacements or designs.
  • Reliable thermal endurance — Rated for 1000 hours at 85°C, supporting sustained operation in elevated-temperature environments.
  • Measured electrical performance — Specified tanδ of 0.3 (20°C, 120 Hz) and defined leakage current support predictable behavior in filter and reservoir roles.
  • Secure snap-in mounting — Snap-in terminal and radial can package provide mechanical stability for through-hole installations.
  • RoHS compliance — Conforms to RoHS directive requirements as listed for the LKS series.

Why Choose LKSN2392MESA?

LKSN2392MESA combines substantial capacitance (3.9 mF) and a 56 V rating in a compact, snap-in radial can specifically positioned for audio equipment and general-purpose power filtering. Its measured electrical parameters—tanδ 0.3 at 20°C/120 Hz, 2.6 A ripple capability, and 1400 µA leakage—make performance predictable for designers balancing size, energy storage, and thermal endurance.

This Nichicon LKS-series part is suited to design teams and procurement focused on compact power-supply components for audio or similar applications that require defined endurance (1000 hours at 85°C) and RoHS compliance. Note: this part is listed as End Of Life; confirm current availability and recommended alternatives when evaluating for new designs.
