Overview of LKG1J392MESAAK – Snap‑In Aluminum Electrolytic Capacitor, 3900 µF, 63 V (Audio Grade)

The LKG1J392MESAAK is a snap‑in aluminum electrolytic capacitor from Nichicon's LKG series, specified for audio equipment and high‑grade audio applications. It combines a 3.9 mF (3900 µF) capacitance with a 63 V rated voltage in a compact radial snap‑in can designed for secure mechanical mounting.

Engineered for audio use, this TYPE‑I (Gold Tune) grade component emphasizes high‑fidelity sound characteristics while offering practical board‑level performance: 2.85 A low‑frequency ripple current (120 Hz), controlled loss angle (tan δ = 0.3 at 20 °C, 120 Hz), and a rated operating range of −40 °C to +85 °C with 1000 hours endurance at 85 °C.

Key Features

  • Audio‑Grade Design (TYPE‑I / Gold Tune)  Designed for high‑grade audio equipment with priority on high‑fidelity sound quality.
  • Capacitance & Voltage  3900 µF nominal capacitance with a 63 V rated voltage, suitable where substantial energy storage is required.
  • Loss Angle (tan δ)  tan δ = 0.3 measured at 20 °C, 120 Hz, providing a defined dissipation characteristic for audio applications.
  • Ripple & Leakage  Low‑frequency ripple current rating of 2.85 A at 120 Hz and specified leakage current of 1480 µA for predictable performance under load.
  • Endurance & Temperature Range  Rated for 1000 hours at 85 °C and an operating temperature range of −40 °C to +85 °C, with capacitance change within ±20% after endurance testing.
  • Mounting & Package  Snap‑in radial can package (φ25 × 45 mm) for secure board retention and tray packing for handling and assembly.
  • Capacitance Tolerance  ±20% tolerance at 120 Hz, 20 °C, matching common audio supply design tolerances.

Typical Applications

  • High‑fidelity audio amplifiers  Specified for use in high‑grade audio equipment to support audio circuitry where fidelity matters.
  • Professional audio equipment  Suited to mixers, preamplifiers, and other professional systems that demand audio‑focused component choices.
  • Audio power supply sections  Provides bulk capacitance and ripple handling for power rails within audio devices.

Unique Advantages

  • Audio‑focused engineering:  Part of the LKG series designed specifically for audio use, prioritizing high‑fidelity sound characteristics.
  • High energy density in a compact can:  3900 µF in a φ25 × 45 mm snap‑in package provides substantial capacitance while keeping board footprint modest.
  • Defined ripple handling:  2.85 A ripple current (120 Hz) gives designers a clear, quantifiable capability for low‑frequency audio power rails.
  • Known dissipation behavior:  tan δ specified at 0.3 (20 °C, 120 Hz) enables predictable thermal and loss planning in audio circuits.
  • Durability at elevated temperature:  1000 hours endurance at 85 °C with specified limits on capacitance change and leakage provides a measured reliability baseline.
