LKS2A182MESY

The LKS2A182MESY from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LKS series designed for audio equipment and general‑purpose use. It provides a high capacitance 1.8 mF value in a compact radial can with snap‑in mounting for robust board retention.

Engineered for applications that need polarized aluminum electrolytic performance, this RoHS‑compliant capacitor offers a 100 V rating, wide operating temperature range, and a defined endurance profile suitable for reliable circuit filtering and energy storage in applicable systems.

Key Features

• Electrical Performance — Rated capacitance of 1.8 mF with a tolerance of -20% to +20% and polarized construction for correct DC application.
• Voltage Rating — 100 V rated for higher‑voltage circuits within the product family limits.
• Ripple Current — Specified ripple current of 2.7 A at 120 Hz, enabling defined AC endurance in applicable smoothing or filtering roles.
• Temperature and Endurance — Operating temperature range of -40 °C to +85 °C and a specified lifetime of 1000 hours at 85 °C with defined post‑test limits for capacitance, tan δ and leakage current.
• Leakage Current Specification — Leakage current after 5 minutes at 20 °C is limited per datasheet formula (not more than 3√CV μA for rated capacitance and voltage), supporting predictable bias behavior.
• Package & Mounting — Radial can with snap‑in terminals for secure PCB mounting; compact size (L: 5 × D: 2 cm) suited to space‑constrained layouts.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Audio‑Focused Design — Part of the LKS series marketed for audio equipment, noted for providing tone quality improvement when replacing smaller standard capacitors.

Typical Applications

• Audio Equipment — Used in audio circuits where replacing smaller standard capacitors can produce a measurable effect on tone quality.
• General Purpose Electronics — Suitable where a polarized aluminum electrolytic with 1.8 mF and 100 V rating is required for filtering, smoothing or energy storage in general‑purpose designs.
• Board‑Mounted Power Modules — Snap‑in mounting provides mechanical stability for applications that benefit from can‑type capacitors with secure PCB attachment.

Unique Advantages

• High Capacitance in Compact Form: 1.8 mF provides substantial charge storage while keeping package dimensions small (L: 5 × D: 2 cm), enabling space‑efficient designs.
• High Voltage Capability: 100 V rating supports designs that operate at elevated DC bus voltages within the series rating.
• Defined Ripple Handling: 2.7 A ripple current (120 Hz) gives a clear performance expectation for AC stress in filtering and smoothing applications.
• Qualified Endurance Window: Specified 1000‑hour endurance at 85 °C with post‑test limits for capacitance, tan δ and leakage current improves predictability for thermal lifecycle planning.
• RoHS Compliance: Meets RoHS directive requirements, simplifying environmental compliance for assembled products.
• Audio‑oriented Series Design: LKS series positioning for audio equipment highlights its suitability where tone quality is a consideration when upgrading from smaller standard parts.
