The LKSN2272MESA is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, designed for audio equipment and general-purpose electronic applications. It delivers a compact, smaller-sized radial can package with a polarized design and a focus on tone quality improvement when replacing smaller standard parts.

Core electrical characteristics include 2.7 mF capacitance at a 56 V rating, ±20% tolerance, and RoHS compliance. The part is specified for operation from -40°C to +85°C with a rated lifetime of 1000 hours at 85°C.

Key Features

• Capacitance & Voltage — 2.7 mF capacitance rated at 56 V, suitable for DC filtering and energy storage in audio and power supply circuits.
• Package & Mounting — Snap-in terminal, radial can (snap-in) package with overall dimensions of 25 × 25 mm (L × D) and a seated height max of 2.5 cm for compact board layouts.
• Audio-focused Performance — Marketed for audio equipment with expected tone quality improvement when replacing small standard products.
• Ripple Current Handling — Specified ripple current of 2.1 A at 120 Hz, supporting low-frequency ripple conditions in power rails.
• Durability & Temperature — Operating range from -40°C to +85°C and rated for 1000 hours at 85°C, with endurance limits defined for capacitance change, tan δ, and leakage current.
• Polarized Design & Tolerance — Polarized electrolytic capacitor with capacitance tolerance of -20% to +20% (±20%).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Main filter and decoupling duties in amplifier and audio power supply circuits where a smaller-sized snap-in capacitor can improve perceived tone quality.
• Power Supply Smoothing — Bulk filtering and ripple suppression on DC rails, leveraging the 2.7 mF capacitance and 2.1 A ripple rating at 120 Hz.
• General-Purpose Electronics — Energy storage and decoupling in consumer and industrial electronics that require a polarized snap-in solution within the specified temperature and lifetime limits.

Unique Advantages

• Compact Snap-in Form Factor: 25 × 25 mm radial can with snap-in terminals provides a smaller footprint for board-level installations without sacrificing capacitance.
• Audio-Targeted Specification: Engineered and marketed for audio equipment, supporting tone quality improvement when used as a replacement for smaller standard parts.
• Verified Ripple Capability: 2.1 A ripple current rating at 120 Hz helps manage low-frequency ripple in power and audio supply lines.
• Wide Operating Temperature: Rated for -40°C to +85°C operation, suitable for a broad range of ambient conditions within the specified lifetime.
• Durability Assurance: Endurance specified as 1000 hours at 85°C, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Regulatory Compliance: RoHS compliant to support designs requiring lead-free/environmental directive conformance.
