Overview of LKG1C392MESABK – 3900 μF, 16 V Snap‑in Aluminum Electrolytic Capacitor (Audio)

The LKG1C392MESABK is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LKG series, specified at 3900 μF and 16 V with ±20% tolerance. It is part of the LKG family designed for audio equipment and prioritizes high‑fidelity sound quality for high‑grade and HD audio applications.

This radial, can‑style snap‑in capacitor provides a compact footprint (φ25 × 20 mm) with electrical characteristics suited to audio power supply and filtering tasks, backed by datasheet specifications for temperature range, endurance and measurable leakage behavior.

Key Features

  • Capacitance & Voltage — 3900 μF nominal capacitance at a rated voltage of 16 V with ±20% tolerance (120 Hz, 20°C).
  • Audio‑Grade Design — Part of the LKG series engineered for use in high‑grade audio and HD audio equipment, with construction and materials selected to prioritize sound quality.
  • Package & Mounting — Radial can with snap‑in terminals; physical size φ25 × 20 mm (L: 2.0 cm × D: 2.5 cm) for compact assemblies requiring secure snap‑in mounting.
  • Thermal and Endurance — Operates from −40°C to +85°C and rated for 1000 hours at 85°C under endurance testing conditions per the datasheet.
  • Electrical Performance — Specified tangent of loss angle (tan δ) of 0.35 and rated ripple current of 1.55 A at 120 Hz; leakage current defined by the datasheet limit of not more than 3√(C·V) μA after 5 minutes at 20°C.
  • Marking — Printed with gold‑colored lettering on a black sleeve for clear identification.
  • Environmental Compliance & Status — RoHS compliant. Product status: End of Life / Discontinued.

Typical Applications

  • High‑grade audio equipment — Designed for use in professional and consumer HD audio systems where capacitor characteristics impact perceived sound quality.
  • Audio amplifiers — Suitable for power supply smoothing and bulk energy storage in amplifier power rails within the specified voltage and ripple ratings.
  • Signal and power filtering for audio electronics — Used where low loss (specified tan δ) and defined ripple handling at 120 Hz are required to support audio performance.

Unique Advantages

  • Tailored for high‑fidelity audio: Built within the LKG series with a design focus on delivering the tone quality required by high‑grade and HD audio equipment.
  • Compact snap‑in form factor: φ25 × 20 mm radial can with snap‑in terminals provides a secure mechanical mount in a small footprint.
  • Measurable electrical characteristics: Specified tan δ (0.35) and ripple current (1.55 A at 120 Hz) give designers clear parameters for audio power supply design.
  • Defined leakage behavior: Leakage current limit follows the datasheet formula (≤ 3√(C·V) μA after 5 minutes at 20°C), enabling predictable bias performance.
  • Temperature and endurance data: Rated −40°C to +85°C with endurance proven at 1000 hours at 85°C in the datasheet, supporting reliability planning for product lifecycles.
  • Regulatory compliance: RoHS compliant, meeting applicable directive requirements cited in the datasheet.

Why Choose LKG1C392MESABK?

LKG1C392MESABK positions itself as a compact, audio‑focused electrolytic capacitor with clear datasheet specifications for capacitance, voltage, loss tangent, ripple current, temperature range, and endurance. It is suited for designers of high‑grade audio equipment and amplifier power supplies who need documented electrical and thermal performance from a snap‑in radial can package.

While the part is listed as End of Life/Discontinued, its specification set and the broader LKG series documentation provide a reliable reference for replacement planning, design validation, and comparison against current inventory or alternate parts within the LKG family.
