LKSN2122MESZ

The LKSN2122MESZ is a snap‑in, radial can aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general‑purpose applications. It delivers 1.2 mF capacitance at a 56 V rating in a compact snap‑in package intended to replace smaller standard parts and help improve tone quality in audio circuits.

Engineered for board‑level snap‑in mounting, this polarized capacitor combines a compact footprint (L: 2.0 cm × D: 2.2 cm) with industry‑relevant electrical and environmental specifications for embedded audio and general‑purpose power filtering designs.

Key Features

• Capacitance & Voltage — 1.2 mF nominal capacitance with a 56 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C), suitable for energy storage and smoothing in audio and power circuits.
• Snap‑in Radial Can Package — Snap‑in mounting for secure board attachment and ease of installation in assemblies that require robust mechanical retention.
• Audio‑Oriented Performance — Sold as a smaller‑sized option within the LKS series and noted for providing an improvement in tone quality when replacing small standard capacitors.
• Operating Range & Reliability — Rated for operation from −40°C to +85°C with an endurance specification of 1000 hours at 85°C, aligning with typical life‑cycle expectations for electrolytic components in consumer and professional audio equipment.
• Ripple Handling — Rated ripple current of 1.45 A at 120 Hz, supporting AC ripple smoothing in power supply and audio signal chains.
• Leakage Current Specification — Series leakage characteristic per datasheet: after 5 minutes at rated voltage and 20°C, leakage current is not more than 3√(C·V) μA (C in μF, V in V).
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used in power supply smoothing and signal‑path decoupling where replacing smaller standard capacitors can affect perceived tone quality.
• General‑Purpose Power Filtering — Suited for general smoothing and bulk decoupling tasks in consumer and professional electronic assemblies that require 1.2 mF at 56 V.
• Board‑Level Snap‑in Designs — Ideal for assemblies that benefit from snap‑in radial can mounting for mechanical retention and simplified PCB placement.

Unique Advantages

• Compact high‑capacitance footprint — 1.2 mF in a 2.0 cm × 2.2 cm body offers a space‑efficient option for designers upgrading from smaller standard capacitors.
• Designed for audible performance improvements — Specified as a smaller‑sized LKS series part with reported tone quality benefits when used as a replacement for small standard products.
• Reliable under thermal stress — Endurance rated to meet specifications after 1000 hours at 85°C, providing predictable aging characteristics for long‑term designs.
• Robust ripple capability — 1.45 A ripple current rating at 120 Hz supports stable smoothing in typical low‑frequency power applications.
• Secure snap‑in mounting — Radial snap‑in can construction simplifies PCB assembly and improves mechanical stability compared with loose leaded parts.
• RoHS compliant — Meets relevant RoHS directives noted in the product description.
