Overview of LKSA2123MESC – Snap-in Aluminum Electrolytic Capacitor, 12 mF, 42 V

The LKSA2123MESC is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LKS series, optimized for audio equipment and smaller-sized assemblies. It is a polarized, radial can capacitor offering 12 mF capacitance at a 42 V rating and is RoHS compliant.

Designed for general-purpose electronic use, the part combines a compact snap-in package with specifications that support tone-quality improvement when used as a replacement upgrade in audio circuits.

Key Features

  • Capacitance & Voltage: 12 mF nominal capacitance at a 42 V rated voltage, specified with ±20% tolerance.
  • Audio-optimized Performance: Marketed for audio equipment and noted for tone-quality improvement when replacing smaller standard parts.
  • Snap-in Radial Package: Snap-in terminal type in a radial, can-style package for board-mount, through-hole assemblies.
  • Operating Range & Lifetime: Rated for operation from −40°C to +85°C with an endurance life of 1000 hours at 85°C.
  • Ripple Current Handling: Rated ripple current of 3.8 A at 120 Hz, supporting typical low-frequency ripple conditions.
  • Polarized Design: Polar capacitor intended for DC applications where polarity is observed.
  • RoHS Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
  • Compact Footprint: Physical size approximately 3.5 × 3.5 cm, providing a smaller-sized option within the LKS series.

Typical Applications

  • Audio Equipment: Used as a replacement or upgrade in audio power circuits where improved tonal characteristics are desired.
  • General-Purpose Electronics: Suited for board-mounted applications requiring a high-capacitance, polarized snap-in capacitor.
  • Electronic Assemblies with Snap-In Mounting: Fits designs that use radial, snap-in can capacitors for secure PCB installation.

Unique Advantages

  • Tonal Improvement Opportunity: Specifically promoted for tone-quality improvement when replacing smaller standard capacitors in audio designs.
  • Robust Ripple Performance: 3.8 A ripple current rating at 120 Hz supports stable operation under common low-frequency ripple conditions.
  • Wide Temperature Capability: −40°C to +85°C operating range with a specified 1000-hour endurance at 85°C for predictable life performance.
  • Secure Snap-In Mounting: Snap-in terminal and radial can package enable straightforward, reliable through-hole installation.
  • Regulatory Compliance: RoHS-compliant construction supports regulatory needs for lead-free assembly.
