Overview of LKG1C392MESBCK – Snap-in Aluminum Electrolytic Capacitor, 3.9 mF, 16 V

The LKG1C392MESBCK is a snap-in aluminum electrolytic capacitor from Nichicon’s LKG series, engineered for audio equipment where fidelity and stable filtering are priorities. Its 3.9 mF (3900 µF) capacitance at a 16 V rating delivers bulk energy storage in a compact package for power-supply smoothing and low-frequency decoupling.

Designed for high-grade audio use, this snap-in can offers a measured tanδ of 0.25 (20°C, 120 Hz), a low-frequency ripple current capability of 2.35 A (120 Hz), and a rated operating range of −40°C to +85°C with 1000 hours endurance at 85°C.

Key Features

  • Capacitance & Voltage 3.9 mF (3900 µF) capacitance at a 16 V rated voltage provides substantial energy storage for audio power rails and smoothing.
  • Audio‑Focused Design Part of Nichicon’s LKG series developed for high-grade and HD audio equipment, prioritizing sound quality in electrolytic filter applications.
  • Low Loss Performance Specified tangent of loss angle (tanδ) of 0.25 measured at 20°C, 120 Hz, supporting low dissipation in audio-frequency filtering.
  • Ripple Current Capability Low-frequency ripple current rating of 2.35 A at 120 Hz for reliable handling of power-supply ripple in amplifiers and audio circuits.
  • Reliability & Endurance Rated life of 1000 hours at 85°C; leakage current specified (740 µA) and capacitance tolerance ±20% to ensure predictable performance over time.
  • Package & Mounting Snap‑in, radial metal-can package (φ30 × 25 mm) for secure chassis or board mounting; packaged in trays for handling and assembly.
  • Environmental Compliance RoHS compliant, suitable for designs requiring lead‑free directive conformance.

Typical Applications

  • High‑fidelity amplifiers — Bulk supply filtering and reservoir capacitance to support stable low‑frequency response and low ripple in amplifier power stages.
  • Professional audio equipment — Power supply decoupling and smoothing in studio racks, mixers, and other high‑grade audio systems.
  • Home and Hi‑res audio systems — Energy storage and ripple suppression for improved background noise and transient response in consumer hi‑fi electronics.

Unique Advantages

  • Audio‑centric engineering — Belongs to the LKG family designed specifically for high‑grade audio applications, aligning component selection with sonic goals.
  • High energy density in a compact can — 3.9 mF capacitance in a φ30 × 25 mm package supports space-constrained designs without sacrificing storage.
  • Measurable low‑frequency performance — 2.35 A ripple current rating at 120 Hz and specified tanδ give engineers quantifiable parameters for power‑supply design.
  • Designed for durable operation — 1000 hours endurance at 85°C and an operating range of −40°C to +85°C provide predictable behavior across typical audio equipment environments.
  • Assembly‑friendly packaging — Snap‑in radial can and tray packing facilitate mechanical retention and handling during production.
  • Regulatory alignment — RoHS compliance helps meet environmental and regulatory requirements for finished products.
