Overview of LKS1E183MESA – Snap‑in Audio Aluminum Electrolytic Capacitor, 25 V, 18 mF

The LKS1E183MESA is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKS series designed for audio equipment and general-purpose circuitry. It provides 18 mF capacitance at a 25 V rating in a compact radial can snap‑in package optimized for replacements where improved tone quality is desired.

As part of the LKS family, this smaller-sized snap‑in capacitor targets audio applications seeking tonal improvement over small standard products while offering standard electrolytic performance characteristics and RoHS compliance.

Key Features

  • Electrolytic Core: 18 mF capacitance with a 25 V rated voltage and polarization suitable for DC power filtering and energy storage in audio and general-purpose circuits.
  • Tolerance & Measurement: Capacitance tolerance ±20% (measured at 120 Hz, 20 °C); series specifies tan δ measurement at 120 Hz, 20 °C.
  • Leakage Current Specification: Leakage current after 5 minutes at rated voltage and 20 °C is specified as not more than 3√(C·V) μA (C in μF, V in V), per the series datasheet.
  • Ripple Handling: Rated low‑frequency ripple current of 3.35 A at 120 Hz, supporting mains‑frequency ripple and typical power supply filtering tasks.
  • Package & Mounting: Radial can, snap‑in terminal package for secure chassis/PCB mounting; physical size approx. L: 5 cm × D: 2.5 cm.
  • Temperature & Endurance: Operating temperature range −40 °C to +85 °C with an endurance rating of 1000 hours at 85 °C as defined for the LKS series.
  • RoHS Compliance: Manufactured to meet RoHS directive requirements (2011/65/EU, (EU)2015/863).
  • Identification: Marked with silver lettering on a black sleeve for clear polarity and part identification.

Typical Applications

  • Audio Equipment: Used in audio amplifier and power supply circuits where the LKS series notes an effect of tone‑quality improvement when replacing small standard products.
  • General Power Filtering: Suitable for general-purpose DC smoothing and decoupling in equipment requiring 18 mF at 25 V with snap‑in mounting.
  • Chassis/PCB Assemblies: Snap‑in package provides secure mechanical mounting for assemblies that benefit from radial can capacitors.

Unique Advantages

  • Tuned for Audio Tone Improvement: Series design intent and part labeling highlight improved tone quality versus small standard products, useful for audio upgrades and replacements.
  • High Ripple Capability: 3.35 A ripple current rating at 120 Hz supports robust handling of mains‑frequency ripple in power supply applications.
  • Compact Snap‑in Format: Radial, snap‑in can delivers secure mounting and straightforward replacement in existing layouts that accept snap‑in components.
  • Wide Operating Range: −40 °C to +85 °C operation and 1000 hours endurance at 85 °C provide predictable performance in typical industrial and consumer environments.
  • Clear Specification Controls: Leakage current formula and measurement conditions (120 Hz, 20 °C) allow engineers to predict behavior and size designs accordingly.
  • Regulatory Compliance: RoHS compliance supports use in products requiring restricted‑substance conformity.
