LKSN2472MESZ

The LKSN2472MESZ is an aluminum electrolytic, snap-in terminal capacitor from Nichicon’s LKS series, engineered for audio equipment and general-purpose circuits. It provides 4.7 mF capacitance at a 56 V rating in a compact radial can snap-in package, offering designers a high-capacitance, serviceable option for power filtering and reservoir applications.

Designed as a smaller-sized LKS variant with audio-focused characteristics, this part can be used as a replacement for smaller standard capacitors to help improve tone quality in audio designs. The device is RoHS compliant and specified for operation across a broad temperature range.

Key Features

• Capacitance & Voltage — 4.7 mF (4.7 millifarads) nominal capacitance with a 56 V rated voltage, suitable for energy storage and smoothing in power rails.
• Snap-in Package — Radial, can-style snap-in mounting for robust PCB retention and straightforward assembly in power-supply and audio chassis layouts.
• Polarized Electrolytic — Polarized design intended for DC smoothing and reservoir duties in general-purpose and audio circuits.
• Operating Temperature — Specified for −40 °C to +85 °C operation, suitable for typical equipment and enclosure environments.
• Endurance — Rated lifetime of 1000 hours at 85 °C when operated at rated voltage, supporting expected service life under elevated-temperature conditions.
• Ripple Handling — Rated ripple current of 2.9 A at 120 Hz, enabling effective AC ripple smoothing in power supplies operating at line frequency rectification.
• Tolerance & Leakage — Capacitance tolerance ±20%; leakage current specified as per LKS series guidance (measurement condition: 5 minutes at rated voltage, 20 °C).
• Compliance — RoHS directive compliant (2011/65/EU, (EU)2015/863).
• Compact Footprint — Physical size approximately L: 4.5 cm × D: 2.2 cm, providing a smaller form factor for constrained enclosures.

Typical Applications

• Audio Equipment — Power supply smoothing and reservoir use where replacement of smaller capacitors can improve perceived tone quality and stability.
• General-Purpose Power Supplies — DC filtering and bulk energy storage for low- to mid-power supply rails in consumer and pro-audio electronics.
• Chassis-Mounted Electronics — Snap-in mounting supports secure installation in equipment with mechanical vibration or frequent handling.

Unique Advantages

• Designed for audio tone improvement: Marketed and specified for audio equipment use, enabling designers to target tone-quality improvements when upgrading from smaller standard parts.
• High capacitance at 56 V: 4.7 mF provides substantial energy storage for reservoir and filtering roles without increasing overall package length substantially.
• Robust snap-in mounting: Radial snap-in terminals offer a secure mechanical connection for through-hole assemblies and easier serviceability.
• Practical ripple capability: 2.9 A ripple current rating at 120 Hz suits line-frequency rectified supplies common in audio and general-purpose designs.
• Temperature and endurance specification: −40 °C to +85 °C rating and 1000-hour endurance at 85 °C give predictable performance and lifecycle planning for deployed equipment.
• Regulatory compliance: RoHS conformity supports use in products that must meet current hazardous-substance restrictions.
