LKS2A182MESZ

The LKS2A182MESZ is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose electronics. It combines a high capacitance (1.8 mF) and 100 V rated voltage in a compact snap-in can to support power filtering and energy storage in board-mounted power circuits.

Engineered for use in audio applications where replacing smaller standard capacitors can yield audible tone-quality improvements, the LKS2A182MESZ is RoHS compliant and built to the endurance characteristics defined for the LKS series.

Key Features

• Capacitance & Voltage: 1.8 mF (1,800 μF) rated at 100 V for high-energy filtering and reservoir duties in power rails.
• Snap-in Mounting: Radial, snap-in can package providing secure board retention for robust mechanical and electrical connection.
• Audio-focused Design: Specified for audio equipment and noted for tone-quality improvement when replacing smaller standard parts.
• Operating Temperature: Specified range of −40 °C to +85 °C suitable for a wide range of general-purpose and audio system environments.
• Endurance: Rated lifetime of 1000 hours at 85 °C with post-test limits: capacitance change within ±20%, tan δ up to 200% of initial specified value, and leakage current not exceeding initial specification.
• Leakage Current Specified: After 5 minutes at rated voltage and 20 °C, leakage current is not more than 3√CV (μA) as defined in the LKS series specifications.
• Ripple Current (Low Frequency): 2.7 A at 120 Hz for handling AC ripple in power supply applications.
• Polarized Electrolytic: Polarized construction for conventional DC filtering and smoothing use cases.
• Compliance: RoHS compliant (2011/65/EU,(EU)2015/863).
• Physical Size: Compact can dimensions L: 4.5 cm × D: 2.2 cm suitable for space-constrained board layouts.

Typical Applications

• Audio Equipment — Power supply filtering and reservoir capacitor where replacing smaller standard capacitors can improve perceived tone quality.
• General-Purpose Power Supplies — Bulk filtering, smoothing and energy storage on board-mounted DC rails.
• Consumer Electronics — Use in electronic assemblies that require a compact, high-capacitance snap-in solution.

Unique Advantages

• High Capacitance at High Voltage: 1.8 mF at 100 V provides significant energy storage capacity for demanding power rails without stepping up package size.
• Robust Board Retention: Snap-in terminal package ensures reliable mounting for through-hole assemblies and simplifies mechanical integration.
• Audio-Targeted Performance: Specified for audio equipment and positioned as a direct upgrade from smaller standard capacitors to influence tone quality.
• Specified Endurance: 1000 hours at 85 °C endurance rating with defined post-test performance limits gives predictable aging characteristics for design planning.
• Defined Leakage and Ripple Specs: Leakage current limit (3√CV) and 2.7 A ripple current at 120 Hz allow designers to size components against system leakage and ripple requirements.
• RoHS Compliance: Conforms to applicable RoHS directives for regulatory alignment in commercial electronics.
