LKSA2682MESZ

The LKSA2682MESZ is a snap‑in, polarized aluminum electrolytic capacitor from Nichicon’s LKS series, designed for smaller-sized applications and audio equipment. It offers 6.8 mF capacitance at a 42 V rating and is intended as a replacement upgrade where improved tone quality is desired.

Built for general‑purpose electronic designs, the LKSA2682MESZ combines a compact snap‑in can package with a defined performance envelope—-including operating range, ripple capability and endurance—-that supports consistent behavior in deployed systems.

Key Features

• Capacitance & Voltage — 6.8 mF capacitance rated at 42 V, suitable for applications requiring high capacitance in a compact form.
• Snap‑In Package — Radial, can snap‑in mounting for secure chassis or PCB retention in compact assemblies; physical size is L: 4.5 × D: 2.2 cm.
• Audio‑Focused Performance — Described for use in audio equipment with reported tone‑quality improvement when replacing smaller standard parts.
• Thermal & Endurance Specifications — Operating temperature range of −40 °C to +85 °C and rated lifetime of 1000 hours at 85 °C with rated voltage applied.
• Ripple Handling — Low‑frequency ripple current capability of 2.9 A at 120 Hz for smoothing and filtering tasks within the stated limits.
• Leakage & Loss Characterization — Leakage current spec: after 5 minutes at rated voltage (20 °C) ≤ 3√(C·V) μA [C in μF, V in V]; tan δ measured at 120 Hz, 20 °C as per datasheet.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU,(EU)2015/863).

Typical Applications

• Audio Equipment — Replacement or upgrade in audio circuits where users seek measurable tone‑quality improvement from a smaller standard part.
• General‑Purpose Electronics — Use in general purpose designs requiring a polarized aluminum electrolytic with snap‑in mounting and high capacitance.
• Chassis‑Mounted Power Modules — Snap‑in package and rated ripple current make it suitable for compact power filter or reservoir capacitor roles within its specified ratings.

Unique Advantages

• Compact High‑Capacitance Option: 6.8 mF in a smaller-sized snap‑in can provides high capacitance where board or chassis space is constrained.
• Audio‑Targeted Design: Specifically called out for audio equipment and noted for tone‑quality improvement when replacing smaller standard products.
• Defined Endurance: Rated for 1000 hours at 85 °C with specified limits on capacitance change, tan δ, and leakage—enabling predictable life behavior under rated conditions.
• Measurable Leakage Specification: Leakage current bounded by the 3√(C·V) formula after 5 minutes at rated voltage, enabling designers to calculate worst‑case leakage for their designs.
• 120 Hz Ripple Capability: 2.9 A ripple current rating at 120 Hz supports smoothing duties within the capacitor’s thermal and endurance limits.
• Compliance and Manufacturing Quality: RoHS compliant and produced as part of Nichicon’s LKS series, providing traceable specifications and datasheet‑defined parameters.
