LKS1E472MESY

The LKS1E472MESY is a Nichicon LKS-series snap-in aluminum electrolytic capacitor designed for audio equipment and general-purpose electronic circuits. It provides 4.7 mF (4700 μF) capacitance at a 25 V rating in a compact snap-in radial can intended as a smaller-sized upgrade to standard parts.

Engineered for audio-focused replacements, this part combines a compact footprint with specifications that support tone-quality improvements when used as a substitute for smaller standard products. It is RoHS compliant.

Key Features

• Capacitance & Voltage  4.7 mF (4700 μF) rated at 25 V for bulk energy storage and decoupling in audio and general-purpose circuits.
• Snap-in Radial Package  Snap-in terminal, radial can package for secure mechanical mounting and straightforward assembly into chassis or power modules; package size φ20 × L25 mm.
• Audio-oriented Performance  Designed as a smaller, higher-tone-quality option within the LKS series—offering improved tonal characteristics when replacing small standard capacitors.
• Electrical Characteristics  Tolerance ±20% (at 120 Hz, 20°C) and specified tan δ = 0.30 (measurement at 120 Hz, 20°C) for predictable AC behavior.
• Ripple Current  Rated ripple current 1.5 A (Arms) at 120 Hz, supporting audio and power applications with moderate dynamic current demands.
• Leakage Current Specification  Leakage current after 5 minutes at 20°C is specified as not more than 3√CV (μA) [C: μF, V: V], per the LKS series datasheet.
• Operating Temperature and Endurance  Rated for −40°C to +85°C with an endurance rating of 1000 hours at 85°C (capacitance change within ±20% after test).
• RoHS Compliant  Complies with RoHS directives (2011/65/EU, (EU)2015/863), meeting environmental substance restrictions.

Typical Applications

• Audio Equipment  Used in audio amplifiers and related equipment where replacing smaller standard capacitors can result in measurable tone-quality improvement.
• General-Purpose Electronic Circuits  Suitable for a wide range of general-purpose applications requiring polarized aluminum electrolytic capacitance at 25 V.
• Component Upgrades / Replacements  A compact replacement option for designers seeking a smaller-sized snap-in capacitor with improved tonal characteristics over certain standard parts.

Unique Advantages

• Compact, Snap-in Form Factor: Enables secure mechanical mounting in radial-can applications while minimizing board and chassis space (φ20 × L25 mm).
• Audio-focused Design: LKS series positioning and product description highlight tone-quality improvement when used as replacements for smaller standard capacitors.
• Measurable Electrical Specs: Clear tolerance (±20%), tan δ (0.30 at 120 Hz), and ripple current (1.5 A at 120 Hz) provide predictable performance for design validation.
• Durability at Elevated Temperature: Endurance rating of 1000 hours at 85°C with defined limits on capacitance change and leakage supports reliable operation in warmer environments.
• RoHS Compliance: Meets current RoHS directives, simplifying environmental compliance for product assemblies.
