LKS1J472MESB

The LKS1J472MESB from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LKS series designed for audio equipment and general-purpose electronic applications. It provides a polarized, high-capacitance solution in a compact radial can snap-in package.

Key values include a nominal capacitance of 4.7 mF at a 63 V rating, RoHS compliance, and specifications focused on audio quality improvements versus comparable small standard products in the LKS family.

Key Features

• Capacitance & Voltage — Nominal 4.7 mF capacitance with a 63 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C), suitable for energy storage and decoupling in mid-voltage circuits.
• Package & Mounting — Radial, can-style snap-in terminal type for secure board-level mounting and reliable mechanical connection.
• Audio-Focused Design — LKS series specification notes an improvement in tone quality when replacing small standard parts, making this part appropriate for audio equipment designs.
• Electrical Performance — Rated ripple current of 3 A at 120 Hz supports high AC current conditions typical in power supply filtering for amplifiers and audio circuits.
• Operating Range & Durability — Operates from −40°C to +85°C with an endurance rating of 1000 hours at 85°C, and defined leakage-current and tan δ limits per the series specification.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used in amplifier and audio power supply circuits where replacement with a compact LKS part can improve perceived tone quality.
• General-Purpose Electronics — Energy storage and smoothing for power rails in consumer and industrial equipment requiring polarized electrolytic capacitance.
• Power Supply Filtering — Bulk filtering and ripple smoothing in mid-voltage power supply sections, leveraging the 63 V rating and 3 A ripple current capability.

Unique Advantages

• Compact, board-ready snap-in format: Radial can snap-in terminals simplify assembly and provide a robust mechanical connection for high-current or vibration-prone environments.
• Audio-oriented performance: Series-level design specifically calls out smaller size and improved tone quality compared to small standard products, helpful for designers targeting audio fidelity.
• High-capacitance mid-voltage rating: 4.7 mF at 63 V offers significant bulk capacitance for mid-voltage systems without increasing footprint excessively.
• Engineered endurance: Rated for 1000 hours at 85°C with defined post-test limits for capacitance, tan δ, and leakage current to support predictable lifetimes in design.
• Regulatory readiness: RoHS compliance supports deployment in regions with restricted substance requirements.
