LKSA2472MESA

The LKSA2472MESA is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LKS series designed for audio equipment and general‑purpose applications. It delivers 4.7 mF capacitance at a 42 V rated voltage in a smaller-sized radial can with snap‑in mounting.

Engineered for applications where tone quality improvement and compact snap‑in installation are required, the LKSA2472MESA combines polarized electrolytic performance with RoHS compliance and specifications drawn from the LKS series endurance and leakage standards.

Key Features

• Capacitance & Voltage — 4.7 mF (4700 μF) rated at 42 V, providing bulk energy storage suitable for audio and general‑purpose circuits.
• Snap‑in Radial Package — Snap‑in terminal, radial can package designed for secure PCB mounting and straightforward assembly in equipment chassis.
• Audio‑Focused Design — Specified as “For Audio Equipment, Smaller‑sized,” intended to offer a tone quality improvement when replacing small standard products.
• Operating Range & Lifetime — Rated operation from −40°C to +85°C with an endurance specification of 1000 hours at 85°C consistent with LKS series requirements.
• Ripple Current — Low‑frequency ripple current rating of 2.5 A at 120 Hz for handling AC ripple in power and audio circuits.
• Leakage Current Specification — After 5 minutes’ application of rated voltage at 20°C, leakage current is specified as not more than 3√CV (μA) per the series datasheet.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20°C for predictable performance in filter and smoothing roles.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.
• Identification — Marked with silver color lettering on a black sleeve for clear part identification.

Typical Applications

• Audio Equipment — Used as a drop‑in upgrade to improve tone quality by replacing smaller standard capacitors in audio power and signal circuits.
• General‑Purpose Electronics — Applicable where general‑purpose polarized electrolytic capacitors are specified for bulk storage, smoothing, and decoupling.
• PCB Assemblies with Snap‑in Mounting — Suitable for equipment designs that employ snap‑in radial cans for reliable mechanical retention and assembly.

Unique Advantages

• Audio‑targeted improvement — Designed and marketed specifically for audio equipment, enabling designers to address tone quality by upgrading from smaller standard parts.
• Compact snap‑in form — Smaller-sized radial can with snap‑in terminals simplifies mechanical integration while conserving board and chassis space.
• Robust ripple handling — A 2.5 A ripple current rating at 120 Hz supports AC ripple demands common in power supplies and audio amplifier circuits.
• Series‑backed endurance — LKS series endurance specifications (1000 h at 85°C) and defined post‑endurance limits provide predictable long‑term behavior for design planning.
• Clear identification — Silver marking on a black sleeve ensures easy visual verification during production and service.
• Regulatory compliance — RoHS compliance supports use in products targeting restricted‑substance conformity requirements.
