Overview of LKSN2123MESC – Snap-in Aluminum Electrolytic Capacitor for Audio Equipment

The LKSN2123MESC from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LKS series designed for audio equipment and general-purpose power filtering. It delivers 12 mF capacitance at a 56 V rating in a smaller-sized, snap-in radial can package aimed at improving tone quality when used as an upgrade from smaller standard capacitors.

Key engineered attributes include polarized construction, RoHS compliance, and specifications targeted for long-term operation in consumer and professional audio applications where stable DC bulk capacitance and reliable ripple handling are required.

Key Features

  • Capacitance & Voltage: 12 mF (12,000 μF) rated at 56 V for substantial bulk energy storage in power supply rails and coupling networks.
  • Package & Mounting: Snap-in, radial can package suitable for secure chassis or PCB mounting where higher capacitance and firm mechanical retention are needed.
  • Operating Range: Designed to operate between −40 °C and +85 °C, enabling use across typical consumer and professional audio environments.
  • Reliability / Lifetime: Specified for 1000 hours at 85 °C; endurance criteria include capacitance change within ±20%, tan δ ≤ 200% of initial specified value, and leakage current not exceeding initial specification after the endurance test.
  • Leakage Current Specification: Leakage current is specified as not more than 3√(C·V) μA after 5 minutes’ application of rated voltage at 20 °C (C in μF, V in V), providing a verifiable leakage limit for design validation.
  • Ripple Handling: Rated ripple current of 4.45 A at 120 Hz, allowing effective smoothing of low-frequency power supply ripple in audio circuits.
  • Tolerance & Polarity: Capacitance tolerance ±20% at 120 Hz, 20 °C; polarized construction typical of electrolytic capacitors.
  • Regulatory: Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

  • Audio Equipment: Bulk and coupling capacitance in amplifiers, preamps, and power supplies where improved tone quality is sought by replacing smaller standard capacitors.
  • Consumer & Professional Audio Systems: Power filtering and reservoir capacitance to support low-frequency headroom and stable supply rails in stereo and multichannel systems.
  • General Purpose Power Filtering: DC link and smoothing in a variety of general-purpose electronics that require polarized high-capacitance components.

Unique Advantages

  • Audio-focused design: Marketed specifically for audio equipment with a smaller-sized snap-in form factor that facilitates upgrades from smaller standard parts to influence tone quality.
  • High bulk capacitance: 12 mF at 56 V provides substantial energy storage for smoothing and transient support without increasing board count.
  • Verified endurance criteria: 1000 hours at 85 °C with defined limits for capacitance change, tan δ, and leakage current, enabling predictable long-term behavior.
  • Measurable leakage performance: Leakage current defined by the 3√(C·V) μA formula after 5 minutes at 20 °C, allowing straightforward verification in incoming inspection or qualification tests.
  • RoHS compliant: Meets RoHS directive requirements for use in regulated regions and designs where hazardous substance limits are required.

Why Choose LKSN2123MESC?

The LKSN2123MESC combines high bulk capacitance, reliable ripple handling, and a snap-in radial can package optimized for audio and general-purpose power applications. Its endurance and leakage specifications provide predictable performance over time at elevated temperatures, while RoHS compliance supports deployment in regulated product lines.

This capacitor is suited to designers and procurement teams specifying upgrade paths from smaller electrolytic parts where improved energy storage and audible performance are desired, or where robust low-frequency filtering and predictable aging characteristics are important design considerations.
