Overview of LKG1C392MESYBK – 3900 µF Snap‑In Aluminum Electrolytic Capacitor, 16 V

The LKG1C392MESYBK is an aluminum electrolytic, snap‑in terminal capacitor engineered for audio equipment applications. It combines a high 3.9 mF capacitance at 16 V with audio‑grade design characteristics from Nichicon’s LKG series to support power smoothing and decoupling in high‑fidelity systems.

Packaged as a radial can with snap‑in terminals and tray packing, this component targets designers of audio amplifiers, receivers, and professional audio gear that require substantial bulk capacitance, defined endurance, and a compact footprint.

Key Features

  • Capacitance and Voltage — 3.9 mF (3900 µF) rated at 16 V for bulk energy storage and smoothing in audio power rails.
  • Audio‑Grade Series Design — Part of Nichicon’s LKG series, designed specifically for audio equipment with priorities on tonal quality and high‑fidelity performance.
  • Snap‑In Terminal Mounting — Radial, can snap‑in package for secure mechanical retention and straightforward board mounting.
  • Low Loss Characteristic — Specified tan δ of 0.35 (measurement conditions per datasheet), supporting low equivalent series loss in audio circuits.
  • Ripple Current Capability — 1.55 A ripple current at 120 Hz to handle dynamic load currents typical in amplifier power supplies.
  • Leakage Current — Specified leakage current of 740 µA after rated voltage application conditions as listed.
  • Temperature and Lifetime — Operating range −40 °C to +85 °C with endurance specified as 1000 hours at 85 °C.
  • Compact Package — Physical size approximately φ20 × 25 mm (L: 2.5 × D: 2.0 cm) for dense assemblies; printed marking in gold on black sleeve per series convention.
  • RoHS Compliant — Conforms to RoHS directive requirements indicated for the LKG series.

Typical Applications

  • High‑Fidelity Amplifiers — Bulk filtering and power‑rail smoothing to reduce ripple and support large instantaneous current draws in audio amplifiers.
  • Home and Professional Audio Receivers — Energy storage and decoupling for stable supply voltages in receivers and integrated audio systems.
  • Mixing Consoles and Studio Equipment — Support for low‑noise power delivery where tonal fidelity and transient response matter.
  • Power Supply Filters for Audio Electronics — Bulk capacitance for smoothing after rectification and for local decoupling near power stages.

Unique Advantages

  • Designed for Audio Quality — Derived from Nichicon’s LKG audio series to align electrical characteristics with audio fidelity considerations.
  • High Bulk Capacitance — 3.9 mF storage reduces voltage sag and improves transient headroom for power stages in audio equipment.
  • Robust Ripple Handling — 1.55 A ripple rating at 120 Hz supports sustained AC stress typical in power supply filtering.
  • Wide Operating Temperature — −40 °C to +85 °C range enables deployment across consumer and pro audio environments.
  • Compact Snap‑In Form Factor — Enables secure mounting and space‑efficient PCB layouts for dense audio assemblies.
  • Standards‑Aware — RoHS compliance supports regulatory requirements for modern electronics manufacturing.
