LKSH2122MESA

The LKSH2122MESA is an aluminum electrolytic capacitor from Nichicon’s LKS series designed as a snap-in terminal, smaller-sized solution for audio equipment and general-purpose electronic circuits. It delivers 1.2 mF capacitance at a 71 V rated voltage in a compact radial can intended for board-mounted snap-in installations.

Engineered for audio replacement and upgrade use, the part is specified to provide audible tone-quality improvement when substituted for small standard products. The device is RoHS compliant (2011/65/EU, (EU)2015/863) and is rated for operation across a wide temperature range with defined endurance at elevated temperature.

Key Features

• Capacitance & Voltage — 1.2 mF capacitance with a 71 V rated voltage, suitable for circuits requiring substantial bulk capacitance in a compact package.
• Package & Mounting — Radial can with snap-in terminals for secure board mounting and straightforward assembly in power and audio assemblies; physical size L: 2 cm × D: 2.5 cm and a seated height up to 2 cm.
• Audio-focused Performance — Specified as “For Audio Equipment” with a stated effect of tone quality improvement when used as a replacement for small standard parts.
• Electrical Tolerance & Polarity — Capacitance tolerance ±20% (−20% to +20%) and polarized construction; leakage current and tan δ follow LKS series specifications.
• Ripple Current & Low-Frequency Handling — Rated ripple current of 1.6 A at 120 Hz for low-frequency smoothing and filtering tasks.
• Temperature & Endurance — Operating temperature range −40°C to +85°C with an endurance rating of 1000 hours at 85°C per the LKS series specification.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Replacement or upgrade in audio power supplies and signal circuits to achieve the described tone-quality improvements over smaller standard capacitors.
• General Purpose Electronics — Bulk energy storage and smoothing in equipment where a compact snap-in radial capacitor is required.
• Board-mounted Power Modules — Snap-in mounting for secure installation in power supply and filter assemblies that benefit from a stable polarized electrolytic capacitor.

Unique Advantages

• Compact Snap-in Packaging — Small L: 2 cm × D: 2.5 cm radial can with snap-in terminals supports space-constrained PCB layouts while providing robust mechanical retention.
• Audio-Targeted Design — Marketed specifically for audio equipment with a stated improvement in tone quality when replacing small standard parts, making it suitable for audio upgrades.
• High Working Voltage — 71 V rating enables use in higher-voltage sections of audio and general-purpose equipment where lower-voltage capacitors are not sufficient.
• Defined Ripple Handling — 1.6 A ripple current at 120 Hz supports low-frequency smoothing duties in power supply circuits.
• Temperature Endurance — Rated for −40°C to +85°C operation and specified endurance of 1000 hours at 85°C, giving predictable performance life at elevated temperature.
• Regulatory Compliance — RoHS compliance to 2011/65/EU and (EU)2015/863 for use in designs requiring restricted substance conformity.
