LKSA2222MESY

The LKSA2222MESY is an aluminum electrolytic capacitor from Nichicon’s LKS series, featuring a snap-in terminal radial can designed for audio equipment and general-purpose use. This smaller-sized, polarized capacitor offers a 2.2 mF capacitance with a 42 V rated voltage and is intended as a compact replacement option where tone-quality improvement versus small standard products is desired.

Engineered for board-mounted snap-in installation, the LKSA2222MESY combines a compact footprint with specified performance characteristics—including operating temperature, ripple current rating and defined endurance criteria—suitable for electronics designers focused on audio and general-purpose power filtering applications.

Key Features

• Capacitance & Voltage — Nominal capacitance: 2.2 mF; rated voltage: 42 V. Capacitance tolerance is ±20% (measured at 120 Hz, 20°C).
• Package & Mounting — Snap-in terminal, radial can (snap-in) package for secure PCB mounting. Physical size: L: 2.5 × D: 2.0 cm with a maximum seated height of 2.5 cm.
• Audio-focused, smaller-sized design — Specified “for audio equipment, smaller-sized” and noted to provide an effect of tone quality improvement when replacing a small standard product.
• Temperature & Endurance — Operating temperature range: −40°C to +85°C. Rated endurance: 1000 hours at 85°C with specified post-test limits (capacitance change within ±20%, tan δ up to 200% of initial specified value, and leakage current less than or equal to initial specified value).
• Ripple & Loss Characteristics — Low-frequency ripple current rating: 1.55 A at 120 Hz. Tangent of loss angle (tan δ) is measured at 120 Hz, 20°C per LKS series specifications.
• Leakage Current Specified — After 5 minutes’ application of rated voltage at 20°C, leakage current is not more than 3√CV (µA), where C is rated capacitance (µF) and V is voltage (V).
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification — Marking: printed with silver color letters on a black sleeve.

Typical Applications

• Audio Equipment — Used in audio circuits where a smaller snap-in electrolytic capacitor is required and replacement from smaller standard parts can affect tone quality.
• General-Purpose Power Filtering — Suitable for smoothing and decoupling in general-purpose electronic designs that require a polarized aluminum electrolytic capacitor with 42 V rating and 2.2 mF capacitance.
• Board-Mounted Power Modules — Snap-in mounting supports secure installation in board-level power sections where higher ripple capability (1.55 A at 120 Hz) is needed.

Unique Advantages

• Compact snap-in footprint: The 2.5 × 2.0 cm can and snap-in terminals provide a space-efficient solution for board-mounted electrolytic capacitors.
• Audio-oriented replacement option: Specified for audio equipment with a stated effect of tone-quality improvement when used as a replacement for small standard products.
• Defined ripple handling: Rated for 1.55 A ripple current at 120 Hz, supporting moderate AC ripple conditions in power supply circuits.
• Specified endurance and stability: 1000 hours at 85°C endurance with clear post-test acceptance criteria for capacitance, tan δ and leakage current.
• Regulatory compliance: RoHS-compliant construction aligns with restricted-substance requirements.
