LKS1E123MESB

The LKS1E123MESB is a snap-in terminal aluminum electrolytic capacitor in Nichicon's LKS series designed for audio equipment and general-purpose power filtering. It provides high bulk capacitance in a compact radial can snap-in package intended as a smaller-sized upgrade to standard parts to help improve tone quality.

Key electrical characteristics include a 12 mF capacitance at 25 V, polarized construction, and a rated ripple current suited to low-frequency power-supply applications. The part is RoHS compliant and engineered for operation across a broad temperature range.

Key Features

• Capacitance & Rated Voltage — 12 mF (12,000 µF) nominal capacitance rated at 25 V with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Package & Mounting — Radial can with snap-in terminals for secure chassis or PCB mounting; compact physical footprint (30 × 30 mm) suitable for space-constrained enclosures.
• Audio-focused Design — Described in the LKS series as “smaller and high-tone quality” compared with the LKG TYPE-1 grade, intended to provide a tonal improvement when used as a replacement upgrade.
• Ripple Current Handling — Rated ripple current of 2.65 A at 120 Hz, enabling effective smoothing in low-frequency power stages.
• Temperature Range & Endurance — Operating range from –40°C to +85°C with an endurance rating of 1000 hours at 85°C under rated voltage conditions.
• Leakage & Loss Characteristics — Leakage current specification measured after 5 minutes at rated voltage not more than 3√CV (µA); typical tan δ specified at 0.30 for this size.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Power-supply smoothing and bulk energy storage in amplifiers and audio systems where a compact, high-capacitance snap-in capacitor can contribute to improved tone quality.
• General-Purpose Power Filtering — Bulk decoupling and filtering in electronic equipment requiring polarized aluminum electrolytic capacitors with robust ripple handling.
• Replacement / Upgrade — Direct replacement or upgrade option for smaller standard capacitors to achieve higher capacitance and the specific tonal characteristics noted for the LKS series.

Unique Advantages

• Audio-oriented acoustic benefit — LKS series positioning highlights a “high-tone quality” effect when used as an upgrade over smaller standard parts, supporting audio design goals.
• Large capacitance in a compact snap-in form — 12 mF in a 30 × 30 mm radial can gives significant bulk capacitance while preserving board/chassis space and mechanical retention.
• Solid ripple capability — 2.65 A ripple current rating at 120 Hz supports effective smoothing in low-frequency power stages.
• Designed for elevated-temperature endurance — Rated for operation to +85°C with a specified 1000-hour endurance at that temperature under rated voltage.
• RoHS compliant — Conforms to current RoHS requirements for easier regulatory integration into commercial designs.
