LKS1H682MESA

The LKS1H682MESA is a snap-in terminal aluminum electrolytic capacitor in Nichicon’s LKS series designed for audio equipment and general-purpose electronic use. It delivers 6.8 mF capacitance at a 50 V rating in a compact radial can snap-in package.

Designed to enable tone-quality improvement when replacing smaller standard capacitors, the LKS1H682MESA combines polarized electrolytic performance with a compact snap-in form factor and RoHS compliance for regulated designs.

Key Features

• Electrical Performance — 6.8 mF capacitance at 50 V with a tolerance of ±20% provides bulk energy storage suitable for smoothing and decoupling in power paths.
• Ripple Handling — Rated ripple current of 3.15 A (120 Hz) supports sustained AC ripple in power-supply applications.
• Polarized Design — Polar capacitor intended for DC applications where correct polarity is observed.
• Mounting & Package — Snap-in terminal, radial can snap-in package for secure vertical PCB installation and simplified assembly.
• Operating Range — Specified temperature range of −40 to +85°C to cover typical consumer and professional audio operating environments.
• Endurance — Rated for 1000 hours at 85°C per the LKS series endurance specification.
• Leakage Current Specification — Leakage current after 5 minutes at rated voltage ≤ 3√(C·V) μA (C in μF, V in V), as defined in the series datasheet.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).
• Physical Size — Compact footprint with dimensions L: 4.5 × D: 2.5 cm for space-constrained designs.

Typical Applications

• Audio Equipment — Replacement or upgrade in audio power supplies to help achieve tone-quality improvement compared to smaller standard capacitors.
• Power Supply Filtering — Bulk decoupling and smoothing in general-purpose DC power circuits where a polarized electrolytic is suitable.
• Electronic Assemblies with Snap-in Mounting — Designs that benefit from secure snap-in terminals for vertical PCB mounting and simplified assembly processes.

Unique Advantages

• Tone-quality improvement potential — Specified in the LKS series as delivering an audible improvement when replacing smaller standard capacitors in audio applications.
• Compact snap-in form factor — Radial can with snap-in terminals combines a small footprint (4.5 × 2.5 cm) with robust mechanical retention for PCB mounting.
