LKSA2392MESA

The LKSA2392MESA from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LKS series designed for audio equipment and general‑purpose power filtering. It is a smaller‑sized, polarized radial can with a 3.9 mF capacitance and a 42 V rating, intended to improve tonal performance when replacing small standard capacitors in audio circuits.

This RoHS‑compliant capacitor offers a compact snap‑in mounting solution with specifications geared toward power supply smoothing and low‑frequency ripple handling in consumer and professional audio applications.

Key Features

• Capacitance and Voltage — 3.9 mF nominal capacitance with a 42 V rated voltage, suitable for energy storage and decoupling in mid‑voltage audio and power circuits.
• Snap‑In Mounting — Snap‑in terminal type in a radial can package for secure PCB retention and straightforward assembly in power supply and chassis layouts.
• Compact Dimensions — Size L: 2.5 × D: 2.5 cm with a seated height up to 2.5 cm, offering a smaller footprint for space‑constrained audio modules while enabling replacement of small standard parts to affect tone quality.
• Electrical Reliability — Polarized construction with capacitance tolerance of ±20% at 120 Hz, 20 °C; leakage current specification follows the series definition (≤ 3√CV μA after 5 minutes at 20 °C), providing predictable behavior in DC‑biased circuits.
• Ripple Current Capability — Rated low‑frequency ripple current of 2.25 A at 120 Hz, supporting smoothing duties in power supplies for amplifiers and audio electronics.
• Temperature and Lifetime — Operating temperature range −40 °C to +85 °C and an endurance of 1000 hours at 85 °C under rated voltage, with specified limits for capacitance change, tan δ, and leakage after endurance testing.
• RoHS Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863), suitable for designs requiring restricted‑substance conformity.

Typical Applications

• Audio Equipment — Power supply smoothing and coupling in amplifiers, preamplifiers, and crossover networks where replacing smaller capacitors can influence perceived tone quality.
• Consumer Electronics Power Supplies — Bulk decoupling and ripple suppression in mid‑voltage supply rails for audio and general‑purpose electronics.
• Professional Audio Modules — Use in rackmount and compact audio modules requiring reliable snap‑in mounting and sustained ripple performance at 120 Hz.

Unique Advantages

• Designed for Audio Tone Improvement — Specified as a smaller‑sized, audio‑focused option in the LKS series to provide a measurable effect on tone when used to replace small standard parts.
• Robust Ripple Handling — 2.25 A ripple current at 120 Hz supports effective smoothing in power rails, reducing audible hum and power‑supply‑related artifacts.
• Secure Snap‑In Mounting — Snap‑in terminals simplify board assembly and ensure mechanical retention in vertical or horizontal chassis installations.
• Predictable Endurance — Rated for 1000 hours at 85 °C with defined limits for capacitance change and tan δ, enabling designers to plan for long‑term performance under rated conditions.
• Regulatory Compliance — RoHS compliance facilitates inclusion in products targeting restricted‑substance requirements.
