LKSN2182MESZ

The LKSN2182MESZ is an aluminum electrolytic capacitor in a snap‑in radial can package, designed for audio equipment and general‑purpose applications. It offers a 1.8 mF capacitance at a 56 V rating with snap‑in mounting for panel or board installation.

Part of Nichicon’s LKS series, this smaller‑sized snap‑in capacitor is intended to support tone‑quality improvements when replacing smaller standard parts, while meeting RoHS environmental requirements.

Key Features

• Electrical Performance — 1.8 mF capacitance with a 56 V rated voltage and polarization suitable for DC smoothing and decoupling in audio circuits.
• Ripple Handling — Rated ripple current of 1.7 A at 120 Hz for low‑frequency power smoothing in audio power supplies.
• Package & Mounting — Snap‑in, radial can package for secure mechanical mounting in equipment chassis and power assemblies.
• Operating Range & Endurance — Operating temperature range of −40°C to +85°C and a rated lifetime of 1000 hours at 85°C for expected long‑term operation under rated conditions.
• Tolerance & Polarization — Capacitance tolerance of −20% to +20% and polarized construction typical of electrolytic capacitors.
• Size — Compact physical footprint with dimensions L: 2.5 × D: 2.2 cm for space‑constrained audio designs.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Power supply smoothing and decoupling in amplifiers, preamplifiers, and other audio signal chains where replacement with a smaller, higher‑tone‑quality part is desired.
• General Power Filtering — DC bus and bulk energy storage in low‑to‑moderate voltage electronic equipment.
• OEM Electronic Assemblies — Snap‑in mounting for secure installation in chassis or power modules for consumer and professional audio products.

Unique Advantages

• Audio‑focused series design — Positioned in the LKS series to deliver smaller size and higher tone quality compared with the referenced LKG TYPE‑1 grade, useful when upgrading from standard small parts.
• Compact radial snap‑in form factor — Enables firm mechanical retention and easy integration into power assemblies without custom hardware.
• Measured ripple capability — 1.7 A at 120 Hz supports effective smoothing of low‑frequency PSU ripple in audio applications.
• Wide operating temperature with defined endurance — Rated for −40°C to +85°C and 1000 hours at 85°C, providing predictable behavior over the product’s specified lifetime.
• Regulatory compliance — RoHS compliance supports use in countries and products that require restricted‑substance adherence.
