Overview of LKSA2183MESC – Snap-in Aluminum Electrolytic Capacitor for Audio Equipment

The LKSA2183MESC is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and general-purpose electronic applications. It offers a compact, smaller-sized can package intended to improve tone quality when replacing small standard products.

Built for power-filtering and smoothing duties, this polarized capacitor combines a rated capacitance of 18 mF with a 42 V rating, snap-in mounting, and specifications tailored for reliable operation across a wide ambient temperature range.

Key Features

  • Capacitance & Voltage — 18 mF capacitance at a rated voltage of 42 V for bulk energy storage and smoothing in power circuits.
  • Package & Mounting — Radial, can-style snap-in package with snap-in terminals for secure board retention and easy assembly; physical dimensions L: 4.5 × D: 3.5 cm and a seated height up to 1.772 inch.
  • Audio-Targeted Design — Series description specifies use for audio equipment with a smaller-sized construction intended to improve tone quality when used as a replacement for small standard products.
  • Temperature & Lifetime — Rated for operation from −40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C.
  • Ripple Current — Rated ripple current of 4.5 A at 120 Hz, supporting AC ripple handling in power-supply and audio circuits.
  • Tolerance & Polarization — Capacitance tolerance of −20% to +20%; polarized device suitable for DC applications where polarity is observed.
  • Leakage & Loss Characteristics — Leakage current specified as not more than 3√CV (μA) after 5 minutes at 20 °C; tangent of loss angle (tan δ) characterized at 120 Hz, 20 °C per the series datasheet.
  • Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

  • Audio Equipment — Bulk filtering and power decoupling in amplifiers and audio power supplies where the series is specified to improve tone quality compared with smaller standard parts.
  • General-Purpose Power Filtering — Smoothing and energy storage in general-purpose electronic power supplies and regulators within the specified voltage and temperature ranges.
  • Consumer Electronics — Power-supply decoupling in consumer devices requiring a radial snap-in capacitor with robust ripple-handling capability.

Unique Advantages

  • Tone-quality oriented: Explicit series design and wording in the product description indicate suitability for audio applications where replacement of smaller standard parts can improve tonal characteristics.
  • High ripple capability: 4.5 A ripple current rating at 120 Hz supports demanding ripple environments common in power supplies and audio circuits.
  • Wide operating temperature: −40 °C to +85 °C rating combined with a 1000-hour endurance at 85 °C provides predictable life performance under elevated temperatures.
  • Secure snap-in mounting: Radial can with snap-in terminals enables reliable mechanical fixation on PCBs for robust assembly processes.
  • RoHS compliant: Meets RoHS directive requirements (2011/65/EU, (EU)2015/863) for restricted substances.
  • Measured electrical limits: Leakage current and tan δ are specified by the series datasheet (leakage ≤ 3√CV after 5 minutes at 20 °C; tan δ measured at 120 Hz, 20 °C), enabling engineering verification against system requirements.
