LKG1E392MESBCK

The LKG1E392MESBCK is a snap‑in terminal aluminum electrolytic capacitor in Nichicon’s LKG series, specified at 3900 µF and 25 V. It is designed for high‑grade audio equipment with priority on high‑fidelity sound quality and is part of the LKG family tailored for audio use.

As a radial, can snap‑in package with polarized construction, this capacitor targets HD audio and other audio system designs that require long‑life electrolytic capacitance in a compact footprint.

Key Features

• Audio‑focused design — Designed for high‑grade audio equipment with emphasis on high fidelity sound quality and HD audio use.
• Grade / Sound quality — Part of the LKG series TYPE‑II (center grade) configuration, using electrode foil intended to provide balanced sound quality for multiple uses.
• Capacitance & tolerance — 3900 µF rated capacitance with ±20% tolerance (measured at 120 Hz, 20 °C).
• Rated voltage — 25 V DC rating suitable for many audio power supply rails.
• Package & mounting — Radial, can snap‑in package (snap‑in terminal) for secure mounting in PCB/power module assemblies; physical size φ30 × 35 mm length (L: 3.5 × D: 3 cm).
• Operating range & lifetime — Specified operating temperature −40 °C to +85 °C with endurance rating of 1000 hours at 85 °C under rated voltage.
• Ripple handling — Rated ripple current 2.8 A at 120 Hz, suitable for typical low‑frequency audio power applications.
• Leakage current specification — Leakage after 5 minutes at 20 °C is specified not to exceed 3√(C·V) µA, where C is capacitance in µF and V is rated voltage in volts.
• RoHS compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Identification — Marked with gold‑color lettering on a black sleeve for clear visual identification.

Typical Applications

• High‑grade audio equipment — Suitable for HD audio systems where tonal quality and fidelity are prioritized.
• Audio power supplies — Used in audio system power rails that require bulk capacitance with defined ripple capability.
• Professional and consumer audio electronics — For designs that demand long operating life and stable performance across −40 °C to +85 °C.

Unique Advantages

• Audio‑tuned series selection — The LKG series’ TYPE‑II center grade uses electrode foil optimized for sound quality, supporting designers focused on tonal balance in audio products.
• Robust thermal and life rating — 1000‑hour endurance at 85 °C provides a verifiable reliability baseline for audio product lifecycles.
• Clear electrical limits — Specified leakage current formula and ripple current rating allow precise design verification against system requirements.
• Compact snap‑in form factor — Radial snap‑in can package (φ30 × 35 mm) simplifies mechanical integration in constrained audio assemblies.
• Regulatory compliance — RoHS conformity supports regulatory requirements for consumer and professional electronics.
