LKS1E123MESA

The LKS1E123MESA is a snap-in aluminum electrolytic capacitor from Nichicon’s LKS series, engineered for audio equipment and general-purpose electronic applications. It delivers high bulk capacitance in a smaller-sized snap-in can, intended to improve tone quality when replacing a smaller standard part.

Key attributes include a 12,000µF capacitance at 25V, polarized construction, snap-in mounting, and RoHS compliance—making it suitable where robust energy reserve and secure board attachment are required in audio and general electronic designs.

Key Features

• Capacitance & Voltage  12,000µF rated capacitance at 25V, with a tolerance of ±20% (–20% to +20%) for predictable bulk energy storage.
• Audio-focused Design  Specified "For Audio Equipment" and described as smaller-sized with tone-quality improvement when replacing small standard parts, making it appropriate for audio-related upgrades and designs.
• Package & Mounting  Radial, can-type with snap-in terminals for secure, low-profile board mounting; physical size approximately 25 × 35 mm (D × L / 2.5 × 3.5 cm).
• Electrical Performance  Rated ripple current of 2.65 A at 120 Hz and a tan δ of 0.30 (measurement at 120 Hz, 20°C) for this size and rating.
• Operating Range & Reliability  Operates from –40°C to +85°C and meets endurance specifications after 1000 hours at 85°C (capacitance change within ±20%, tan δ within 200% of initial specified value, leakage current ≤ initial value).
• Polarized Construction  Designed as a polarized electrolytic capacitor; leakage current limits follow the datasheet specification of ≤ 3√CV (µA) after 5 minutes at rated voltage, 20°C.
• RoHS Compliant  Compliant with the RoHS directive (2011/65/EU, (EU)2015/863), and marked with silver lettering on a black sleeve.

Typical Applications

• Audio Equipment  Intended for use in audio equipment where replacing a smaller standard capacitor can contribute to improved tone quality.
• General-Purpose Electronics  Suitable for applications requiring high bulk capacitance in a snap-in aluminum electrolytic package within the specified temperature and lifetime limits.
• Upgrades & Replacements  Aimed at designers and technicians replacing smaller capacitors to increase energy reserve and potentially affect audio characteristics.

Unique Advantages

• High Bulk Capacitance: 12,000µF provides significant energy storage for filtering and decoupling tasks without increasing diameter beyond the LKS smaller-sized profile.
• Audio-Targeted Benefit: Specifically described for audio equipment with an intended tone-quality improvement when used as a replacement for smaller standard parts.
• Snap-in Mounting: Snap-in terminal design ensures a secure mechanical and electrical board connection suitable for upright can installations.
• Designed for Continuous Use at Elevated Temperature: Rated for 1000 hours at 85°C with defined endurance limits for capacitance, tan δ, and leakage current.
• Measurable Ripple Handling: 2.65 A ripple current rating at 120 Hz gives a quantifiable baseline for AC performance in relevant designs.
• Regulatory Compliance: RoHS compliant construction and clear sleeve marking simplify inclusion in regulated assemblies.
