Overview of LKG1J122MESYCK – Snap‑in Aluminum Electrolytic Capacitor, 1200 µF · 63 V

The LKG1J122MESYCK is an aluminum electrolytic capacitor in a snap‑in radial can designed for audio applications. It delivers 1.2 mF (1200 µF) capacitance at a 63 V rating in a compact φ20 × 45 mm package.

Part of Nichicon's LKG series engineered for high‑grade audio equipment, this unit combines audio‑focused design with measurable electrical performance: significant ripple handling, low leakage characteristics, and a predictable 1000‑hour endurance at elevated temperature.

Key Features

  • Capacitance & Voltage — 1.2 mF (1200 µF) rated at 63 V for bulk energy storage and decoupling in audio power stages.
  • Snap‑in Radial Can Package — Snap‑in mounting for secure chassis or board installation in compact audio assemblies; package dimension φ20 × 45 mm (L: 4.5 × D: 2.0 cm).
  • Ripple Current Handling — 2.35 A ripple current at 120 Hz, supporting power filtering and smoothing in audio power supplies.
  • Low Leakage — Specified leakage current of 820 µA; series specification also documents leakage limits per the LKG series test conditions.
  • Operating Temperature & Endurance — Rated for −40 °C to +85 °C with endurance specified as 1000 hours at 85 °C, providing predictable aging behavior for design validation.
  • Polarized, ±20% Tolerance — Polar capacitor with capacitance tolerance of −20%/+20% (±20%) at 120 Hz, 20 °C.
  • RoHS Compliant — Conforms to RoHS directive requirements as noted for the LKG series.
  • Audiophile‑oriented Series Design — LKG series is specified for audio use and designed to prioritize high‑fidelity sound quality in HD audio equipment.

Typical Applications

  • High‑grade Audio Equipment — Use in professional and consumer audio systems where fidelity and stable filtering are required.
  • Audio Power Supplies — Bulk smoothing and decoupling in power supply sections for amplifiers and preamplifiers.
  • HD Audio Systems — Component in signal chain power conditioning to help maintain tonal integrity in high‑resolution audio designs.

Unique Advantages

  • Audio‑focused specification: From the LKG series, the part is engineered specifically for high‑tone quality audio applications.
  • High ripple capability: 2.35 A at 120 Hz supports demanding filter and smoothing duties in audio power stages.
  • Predictable endurance: Rated 1000 hours at 85 °C gives designers a defined lifecycle parameter for reliability planning.
  • Compact snap‑in form factor: φ20 × 45 mm radial can provides high capacitance in a small footprint for space‑constrained audio assemblies.
  • Controlled leakage: Specified leakage current (820 µA) and series leakage limits help maintain low noise and stable bias conditions in audio circuits.
  • Regulatory compliance: RoHS status simplifies integration into products requiring restricted‑substance compliance.

Why Choose LKG1J122MESYCK?

LKG1J122MESYCK is positioned for designers and manufacturers of high‑fidelity audio equipment who need a compact, snap‑in electrolytic capacitor with clear, measurable performance: 1200 µF at 63 V, robust ripple capability, controlled leakage, and a defined 1000‑hour endurance at 85 °C. Its specifications map directly to power supply filtering and energy storage needs common to HD audio and professional audio electronics.
