LKSA2222MESA

The LKSA2222MESA is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and other general-purpose electronic applications. It is a polarized, radial can-style capacitor in the Nichicon LKS series, optimized for smaller-sized installations where a compact snap-in solution is required.

Specified for 2.2 mF capacitance at 42 V with ±20% tolerance, this part targets designers seeking measurable tonal improvement when replacing smaller standard parts. It is RoHS compliant and offers defined ripple handling and endurance characteristics for reliable operation in typical electronic environments.

Key Features

• Capacitance & Voltage: 2.2 mF rated capacitance at 42 V with ±20% tolerance, suitable where polarized aluminum electrolytic storage is required.
• Package & Mounting: Snap-in, radial can package for secure mechanical mounting in chassis or PC assemblies requiring snap-in terminals.
• Compact Footprint: Physical size L: 2 cm × D: 2.5 cm provides a smaller-sized option within the LKS series for space-constrained audio and general-purpose designs.
• Operating Range: Rated for operation from −40°C to +85°C, enabling use across a broad ambient temperature range.
• Endurance: Designed with a rated lifetime of 1000 hours at 85°C when operated at rated voltage, with defined post-test limits for capacitance, tan δ and leakage current.
• Ripple Handling: Low-frequency ripple current capability of 1.55 A at 120 Hz, suitable for typical power smoothing applications at that frequency.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment: Used as replacement or upgrade capacitors in audio circuits where swapping from smaller standard parts can produce a noticeable tonal improvement.
• General-Purpose Electronics: Serves as a polarized electrolytic component for energy storage and decoupling in a variety of general-purpose electronic designs.
• PC Board Assemblies with Snap-in Mounting: Suited for assemblies that require snap-in radial can capacitors for mechanical retention and straightforward installation.

Unique Advantages

• Audio-focused performance: Specifically noted for tone-quality improvement when used as a replacement for smaller standard parts in audio equipment.
• Defined ripple capability: 1.55 A at 120 Hz provides clear specification for low-frequency ripple handling in applicable circuits.
• Compact LKS-series footprint: Smaller-sized 2.0 cm × 2.5 cm dimensions allow designers to reduce board or chassis space compared to larger snap-in options.
• Wide operating temperature: −40°C to +85°C rating supports use across common ambient conditions found in consumer and professional electronics.
• Specified endurance: 1000 hours at 85°C rated lifetime with post-test limits for capacitance, tan δ and leakage current to help predict long-term behavior.
• RoHS compliance: Conforms to current RoHS requirements for restricted substances, supporting regulatory-aligned designs.
