Overview of LKS1H183MESC – Snap-in Terminal Type Aluminum Electrolytic Capacitor for Audio Equipment

The LKS1H183MESC is an aluminum electrolytic capacitor in Nichicon’s LKS series, designed as a smaller-sized, snap-in terminal component for audio equipment and general-purpose electronic use. It delivers a nominal 18 mF capacitance with a 50 V rated voltage and polarized construction suitable for power filtering and energy storage in audio circuits.

Engineered for component-level upgrades, the LKS1H183MESC is described as offering an effect to tone quality improvement when replacing smaller standard products. The part is RoHS compliant and specified for operation across a broad temperature range.

Key Features

  • Capacitance & Voltage — Nominal 18 mF capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
  • Mounting & Package — Snap-in terminal, radial can (snap-in) package for secure PCB installation.
  • Audio-focused Design — Listed for use in audio equipment; intended as a smaller-sized upgrade to improve tone quality versus small standard parts.
  • Temperature & Lifetime — Operates from −40°C to +85°C with an endurance rating of 1000 hours at 85°C.
  • Ripple Handling — Rated ripple current of 4.9 A at 120 Hz, suitable for smoothing and decoupling in power rails for audio applications.
  • Leakage Current Specification — Meets leakage current limits: after 5 minutes’ application of rated voltage at 20°C, leakage current is not more than 3√CV (μA) (C: rated capacitance in μF, V: voltage in V).
  • Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).
  • Physical Size — Compact dimensions: L: 5 × D: 3.5 cm, suitable for equipment where reduced can size is required.

Typical Applications

  • Audio Equipment — Used in amplifier and playback circuits where replacing smaller capacitors can influence tone quality and filtering performance.
  • Power Supply Smoothing — Bulk energy storage and ripple smoothing on DC rails in consumer and professional audio electronics.
  • General Purpose Electronic Equipment — Polarized capacitive storage and decoupling in a variety of electronic designs requiring reliable electrolytic performance and snap-in mounting.

Unique Advantages

  • Audio-oriented upgrade: Specified as a smaller-sized alternative intended to improve tone quality when replacing small standard components.
  • Robust ripple capability: 4.9 A ripple current rating at 120 Hz supports demanding AC ripple conditions commonly found in audio power supplies.
  • Wide operating range: −40°C to +85°C operation with a 1000-hour endurance at 85°C provides predictable behavior across typical equipment environments.
  • Secure snap-in mounting: Radial, snap-in terminal package offers firm board retention for through-hole assembly processes.
  • Controlled leakage behavior: Leakage current limited by the 3√CV specification, enabling predictable startup and bias characteristics in designs.
  • RoHS compliant: Meets current RoHS directives for environmental and regulatory alignment.

Why Choose LKS1H183MESC?

The LKS1H183MESC positions itself as a compact, audio-focused aluminum electrolytic solution that balances capacitance, ripple handling and thermal endurance for equipment designers seeking measurable tonal and power-filtering improvements. Its snap-in construction and radial can package make it practical for through-hole assembly while offering robust electrical characteristics for general-purpose and audio-specific circuits.

This capacitor is well suited to designers and procurement teams specifying components for consumer and professional audio equipment or other electronic applications that require reliable polarized energy storage, predictable leakage behavior, and RoHS compliance backed by Nichicon’s LKS series specifications.
