LKS2A681MESY

The LKS2A681MESY is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose board applications. It pairs a compact radial can snap-in package with a 680 µF capacitance at a 100 V rated voltage to provide bulk energy storage and smoothing where higher voltage and compact size are required.

Engineered to deliver tone-quality improvement when replacing small standard products, this RoHS-compliant capacitor offers targeted electrical and reliability characteristics for system-level audio and power applications.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 100 V, with a tolerance of ±20%, suitable for higher-voltage reservoir and smoothing duties.
• Package & Mounting — Radial can, snap-in terminal type for secure board mounting and straightforward assembly into power and audio chassis.
• Audio-focused Design — Smaller-sized LKS series construction with reported tone-quality improvement when used as a replacement for small standard products.
• Electrical Performance — Specified ripple current of 1.6 A at 120 Hz and measurement of tan δ at 120 Hz; leakage current limited to not more than 3√CV (µA) after 5 minutes at 20°C.
• Reliability & Lifetime — Endurance rated for 1000 hours at 85°C with defined limits: capacitance change within ±20%, tan δ up to 200% of initial specified value, and leakage current not exceeding the initial specified value after recovery to 20°C.
• Operating Range & Marking — Operates from −40°C to +85°C and is marked with silver lettering on a black sleeve for clear identification.
• Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Dimensions — Physical size L: 2.5 cm × D: 2.0 cm for space-conscious designs.

Typical Applications

• Audio Equipment — Used as power supply reservoirs or smoothing capacitors in amplifiers and audio circuits where replacing smaller standard parts can yield audible tone-quality improvements.
• Power Supply Filtering — Bulk filtering and decoupling in higher-voltage power rails up to 100 V, leveraging 680 µF capacitance for energy storage and ripple reduction.
• Amplifier Power Rails — Provides charge reserve and transient support for power amplifiers and driven stages, with 1.6 A ripple rating at 120 Hz.
• General Industrial Electronics — Suitable for board-level applications requiring a polarized aluminum electrolytic capacitor with robust endurance at elevated temperature.

Unique Advantages

• Compact, Snap-in Form Factor: Radial can with snap-in terminals enables straightforward board mounting in space-constrained assemblies.
• High-Voltage Capability: 100 V rating expands applicability to higher-voltage power rails compared with lower-voltage electrolytics.
• Designed for Audio Improvements: LKS series smaller-sized construction is intended to provide tone-quality benefits when used to replace small standard products.
• Measured Electrical Limits: Explicit leakage current and ripple current specifications (3√CV μA leakage formula; 1.6 A at 120 Hz ripple) support predictable circuit behavior.
• Thermal Endurance: 1000-hour endurance at 85°C with defined post-test limits for capacitance, tan δ and leakage supports reliable long-term operation under elevated temperature stress.
• RoHS Compliant: Meets RoHS directives, facilitating use in regulated markets and assemblies requiring restricted substances compliance.
