LKS2A681MESA

The LKS2A681MESA is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, engineered for audio equipment and general-purpose electronic applications. This polarized, radial can capacitor provides 680 µF capacitance at a 100 V rating in a smaller-sized snap-in package designed for board-mounted power filtering and smoothing.

Key value comes from its audio-oriented design intent (noted as delivering tone-quality improvement when replacing small standard products), RoHS compliance, and a compact form factor that supports reliable performance across a –40 °C to +85 °C operating range.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable for medium-voltage smoothing and energy-storage use in power circuits.
• Snap-in Radial Can Package — Snap-in terminal mounting for secure board retention and straightforward installation in power supply assemblies; package case described as radial, can - snap-in.
• Audio-Oriented Performance — Specified for audio equipment with a claimed tone-quality improvement when replacing small standard capacitors, reflecting the LKS series design focus.
• Temperature and Endurance — Operating temperature range of –40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C when subjected to rated voltage.
• Ripple Handling — Rated ripple current of 1.6 A at 120 Hz, suitable for low-frequency smoothing applications in power rails.
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), meeting restricted-substances requirements for many commercial and consumer products.
• Compact Size — Smaller-sized part with dimensions L: 2 × D: 2.5 cm, enabling use where board space is constrained.

Typical Applications

• Audio Equipment — Intended for audio circuits where replacement of smaller standard capacitors can contribute to perceived tone-quality improvements and cleaner power delivery.
• General-Purpose Power Filtering — Board-mounted smoothing and decoupling in general electronic equipment that require polarized electrolytic capacitance at higher voltage.
• Consumer and Electronic Assemblies — Compact snap-in mounting makes this capacitor suitable for consumer devices and electronic assemblies needing reliable bulk capacitance with secure mechanical retention.

Unique Advantages

• Compact, board-friendly form — Small L: 2 × D: 2.5 cm footprint and snap-in terminals simplify mechanical integration on PCBs while saving space.
• Audio-focused design intent — LKS series positioning highlights tone-quality improvement when replacing small standard products, supporting designers targeting audio performance.
• Robust operating range — –40 °C to +85 °C rating and a 1000-hour endurance at 85 °C under rated voltage provide a clear baseline for thermal and lifetime planning.
• High-voltage capability — 100 V rating enables use on higher-voltage rails compared with lower-voltage electrolytic options.
• Measured ripple specification — 1.6 A ripple current at 120 Hz gives a verifiable metric for low-frequency smoothing design calculations.
• Regulatory compliance — RoHS compliance helps meet environmental and supply-chain requirements for many markets.
