LKS1J272MESY

The LKS1J272MESY is a Nichicon LKS series aluminum electrolytic capacitor in a radial, snap-in can package designed for audio equipment and general-purpose applications. It is a polarized, snap-in terminal type intended as a smaller-sized upgrade to standard products with an emphasis on tone quality improvement in audio circuits.

Key electrical and environmental characteristics include 2.7 mF (2700 μF) nominal capacitance at 63 V rating, ±20% tolerance, -40 °C to +85 °C operating range, RoHS compliance, and a specified lifetime of 1000 hours at 85 °C.

Key Features

• Capacitance & Voltage — 2.7 mF (2700 μF) nominal capacitance with a 63 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C).
• Audio-Optimized Design — Series description highlights a smaller size and improved tone quality when replacing small standard products, making it suitable for audio-focused circuits.
• Snap-in Radial Package — Radial, can-style snap-in mounting simplifies PCB assembly for chassis- or board-mounted power sections.
• Temperature & Lifetime — Rated for -40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C.
• Ripple Handling — Specified low-frequency ripple current of 2.25 A at 120 Hz for handling ripple in power circuits.
• RoHS Compliant — Meets RoHS directive (2011/65/EU and (EU)2015/863) requirements.

Typical Applications

• Audio Equipment — Replacement and upgrade in audio power stages where improved tone quality from a smaller standard capacitor is desirable.
• Power Supply Smoothing — Bulk filtering and smoothing in general-purpose power supplies that require a snap-in radial capacitor.
• Amplifier Modules — Energy storage and ripple suppression in amplifier power circuits within the stated temperature and lifetime limits.

Unique Advantages

• Audio-focused improvement: Marketed specifically for tone-quality improvement versus small standard products, enabling targeted component upgrades in audio designs.
• High capacitance at elevated voltage: 2.7 mF at 63 V provides substantial capacitance value in a compact snap-in can for demanding circuits.
• Assembly-friendly snap-in package: Radial, snap-in terminals facilitate secure board or chassis installation without specialized mounting hardware.
• Designed for real-world conditions: Operating range of -40 °C to +85 °C and a 1000-hour endurance rating at 85 °C align with typical equipment life-cycle expectations.
• Measured ripple capability: Specified 2.25 A ripple current at 120 Hz supports applications with low-frequency AC ripple components.
• Regulatory compliance: RoHS compliance supports use in RoHS-regulated product lines.
