Overview of LKG1E122MESYCK – Aluminum Electrolytic Snap‑in Capacitor, 1.2 mF, 25 V

The LKG1E122MESYCK is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LKG series, specified at 1.2 mF (1200 µF) and 25 V. It is designed specifically for high‑grade audio equipment and HD audio applications, prioritizing high‑fidelity sound quality through Type‑III construction and gold‑plated terminals.

Packaged as a radial can with snap‑in mounting, this polarized capacitor delivers audio‑focused performance with a wide operating temperature range and defined endurance characteristics suitable for demanding audio circuitry.

Key Features

  • Audio‑grade Type‑III construction — Type‑III (Super Through) grade with gold‑plated terminals, developed to prioritize low drag and high tone quality for high‑fidelity audio.
  • Capacitance & voltage — 1.2 mF (1200 µF) rated capacitance at 25 V with ±20% tolerance, suitable for filtering, coupling and reservoir roles in audio circuits.
  • Snap‑in radial can package — Snap‑in terminal mounting for secure board or chassis attachment in through‑hole assemblies.
  • Electrical performance — Ripple current rated at 1.2 A (120 Hz), with leakage current specified in the datasheet (≤ 3√CV μA after 5 minutes at 20°C).
  • Operating range and endurance — Rated for −40°C to +85°C with an endurance/lifetime of 1000 hours at 85°C under rated voltage.
  • Polarized design & marking — Polar capacitor with gold‑color lettering printed on a black sleeve for clear polarity and grade identification.
  • RoHS compliant — Conforms to 2011/65/EU and (EU)2015/863 requirements.
  • Compact footprint — Physical size: approximately φ20 × 25L (L: 2.5 × D: 2 cm), enabling use in space‑constrained audio equipment.

Typical Applications

  • High‑end audio amplifiers — Used for reservoir and smoothing duties where capacitor quality impacts perceived tone and dynamic response.
  • Professional AV and studio equipment — Employed in power supply and signal path stages for HD audio systems requiring fidelity‑oriented components.
  • DACs, preamplifiers and signal conditioning — Applied where low drag and consistent performance contribute to accurate reproduction of audio signals.

Unique Advantages

  • Designed for fidelity: Type‑III construction and gold‑plated terminals reduce contact drag and support improved tonal characteristics important to HD audio designs.
  • Purposeful electrical rating: 1.2 mF at 25 V with 1.2 A ripple current (120 Hz) provides measurable smoothing and reservoir capacity for audio power rails.
  • Durability under stress: Specified 1000 hours at 85°C endurance ensures predictable long‑term behavior in typical audio operating environments.
  • Clear grading and marking: Gold‑color lettering on a black sleeve makes grade and polarity identification straightforward during assembly and maintenance.
  • Regulatory compliance: RoHS conformity supports use in products targeting regulated markets.
  • Secure mechanical mounting: Snap‑in terminal can package simplifies integration into through‑hole assemblies for robust board or chassis attachment.
