LKSN2272MESY

The LKSN2272MESY is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general‑purpose electronic assemblies. It offers a compact, smaller‑sized snap‑in package intended to simplify board mounting while addressing requirements for higher capacitance in audio circuits.

Key electrical characteristics include a capacitance of 2.7 mF (2700 μF) at a rated voltage of 56 V, a polarized construction, and RoHS compliance (2011/65/EU, (EU)2015/863). The part is specified for operation from −40°C to +85°C with an endurance rating of 1000 hours at 85°C.

Key Features

• Capacitance & Rated Voltage — 2.7 mF (2700 μF) nominal capacitance with a 56 V rated voltage and tolerance of −20% to +20%.
• Snap‑in Mounting & Package — Radial, can‑style snap‑in package for secure board installation in panel and chassis assemblies.
• Audio‑Focused Design — Specified for audio equipment; the smaller‑sized LKS variant is positioned to provide an audible tone improvement when replacing smaller standard capacitors.
• Temperature & Endurance — Rated for −40°C to +85°C operation with a life specification of 1000 hours at 85°C.
• Ripple Current — Low‑frequency ripple current rating of 2.1 A at 120 Hz, suitable for applications with moderate ripple demands.
• Leakage & Loss Characteristics — Leakage current specified as not more than 3√CV (μA) after 5 minutes at 20°C; tan δ and low‑temperature impedance references are provided in the LKS series datasheet.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Designed for use in audio circuits where replacing smaller standard capacitors can affect tone quality.
• General‑Purpose Electronic Assemblies — Suitable for assemblies requiring polarized electrolytic capacitance with snap‑in mounting for mechanical stability.
• Power Filtering in Enclosures — Snap‑in radial can package supports secure mounting in power and filter modules within equipment enclosures.

Unique Advantages

• Higher Working Voltage: 56 V rating provides headroom for circuits that require elevated DC filtering or coupling voltages.
• Compact, Snap‑in Form Factor: Smaller‑sized radial snap‑in package simplifies mechanical retention on PCBs and in chassis-mounted power assemblies.
• Audio‑Oriented Performance: LKS series positioning and part sizing are intended to deliver tone quality improvements when used as replacements for smaller standard capacitors.
• Defined Endurance: Specified 1000 hours at 85°C enables predictable long‑term behavior for design planning and reliability assessments.
• Measured Ripple Capability: Rated ripple current of 2.1 A at 120 Hz provides a verified capability for moderate ripple environments.
• Regulatory Compliance: RoHS compliance supports designs targeting restricted‑substance requirements.
