LKS2A272MESB

The LKS2A272MESB is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, engineered for audio equipment and general-purpose electronic designs. It combines a compact, smaller-sized snap-in can with a 2.7 mF capacitance and a 100 V rating to support higher-voltage smoothing and decoupling tasks.

Designed for audio applications, the part can be used as a replacement for smaller standard products to help improve tone quality. It is RoHS compliant and built for reliable operation across a broad temperature range.

Key Features

• Electrical Performance — 2.7 mF capacitance with ±20% tolerance and a 100 V rated voltage for higher-voltage rail applications.
• Audio-focused Design — Snap-in terminal type and smaller-sized construction intended for audio equipment; documented as able to improve tone quality when used in place of small standard products.
• Ripple and Leakage — Rated ripple current: 3.2 A at 120 Hz. Leakage current after 5 minutes at rated voltage and 20°C is specified as not more than 3√CV (µA), where C is capacitance in µF and V is voltage in V.
• Mechanical & Packaging — Radial, snap-in can package for secure chassis or PCB mounting; nominal dimensions L: 3.5 × D: 3 cm provide a compact footprint for power stages.
• Temperature & Reliability — Operating temperature range from −40°C to +85°C with an endurance specification of 1000 hours at 85°C. Endurance recovery limits: capacitance change within ±20%, tan δ up to 200% of initial spec, and leakage current less than or equal to the initial specified value after the endurance test.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification — Marked with silver letters on a black sleeve for clear part identification.

Typical Applications

• Audio Equipment — Power supply smoothing and decoupling in amplifiers and audio circuits, where replacing smaller standard capacitors can contribute to improved tone quality.
• Power Supply Filtering — Bulk filtering and energy storage on higher-voltage rails up to 100 V in general-purpose electronic equipment.
• Consumer and Professional Audio Gear — Used in systems requiring a compact, snap-in mounting style that supports robust ripple current handling.
• General-Purpose Electronics — Applications requiring a polarized electrolytic capacitor with defined endurance at elevated temperature and dependable leakage characteristics.

Unique Advantages

• Audio-optimized, smaller-sized form: Intended for audio equipment and noted for potential tone-quality improvement compared to small standard parts.
• High-voltage capability: 100 V rating enables use on higher-voltage rails where lower-voltage capacitors cannot be applied.
• Robust ripple handling: 3.2 A ripple current (120 Hz) supports demanding smoothing duties in power circuits.
• Long-term endurance: Specified for 1000 hours at 85°C with clear post-test limits for capacitance, tan δ, and leakage current.
• Secure mechanical mounting: Snap-in radial can package simplifies installation in chassis and power assemblies.
• Regulatory compliance: RoHS compliant to the specified directives for environmentally conscious designs.
