LKG1H392MESBBK

The LKG1H392MESBBK is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon's LKG series, specified at 3.9 mF (3900 µF) and 50 V. It is engineered for high‑grade audio equipment with design emphasis on sound quality for HD audio applications.

This unit is part of the LKG family’s TYPE‑II (center grade) offering and combines high capacitance, robust ripple capability, and industry‑standard snap‑in mounting to support power filtering and supply decoupling in audio systems.

Key Features

• Electrical Capacity — 3.9 mF (3900 µF) rated at 50 V with ±20% tolerance, suitable for bulk energy storage and smoothing in audio power rails.
• Audio‑Focused Construction — LKG series design targeted to high‑fidelity audio; the TYPE‑II (BK) center grade balances sound quality and broad usability within audio equipment.
• Mounting and Package — Snap‑in terminal, radial can package for secure chassis mounting and straightforward PCB integration in power assemblies.
• Operational Range — Rated for operation from −40°C to +85°C, with endurance specified at 1000 hours at 85°C under rated voltage.
• Ripple and Low‑frequency Performance — Rated low‑frequency ripple current of 3 A at 120 Hz; loss angle (tan δ) and impedance characteristics are referenced at 120 Hz.
• Leakage and Stability — Leakage current spec: after 5 minutes at rated voltage and 20°C not more than 3√(C·V) µA; endurance limits capacitance change to within ±20% after 1000 hours at 85°C.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Compact radial can dimensions approximately L: 3.5 cm × D: 3.0 cm for space‑conscious audio designs; marked with gold‑color print on a black sleeve for clear identification.

Typical Applications

• High‑fidelity amplifiers — Bulk supply decoupling and smoothing to support stable power delivery and reduced supply ripple in audio amplifier stages.
• AV receivers and preamplifiers — Energy storage and filtering in analog/digital sections where audio performance and low noise are priorities.
• Audio power supplies — Smoothing and ripple management in power supply rails feeding sensitive audio circuitry and digital audio processors.

Unique Advantages

• Audio‑grade tuning: Part of the LKG series specifically designed for audio use, providing a balance of tonal quality and practical performance for HD audio systems.
• High capacitance at moderate voltage: 3.9 mF at 50 V supplies substantial energy storage in a compact snap‑in can, reducing the need for multiple lower‑value parts.
• Reliable endurance: Rated endurance of 1000 hours at 85°C under rated voltage with defined limits for capacitance change and leakage, giving predictable long‑term behavior in equipment thermal environments.
• Practical mounting: Snap‑in terminal design enables robust chassis or board attachment for power modules and enclosures commonly used in audio gear.
• Measured low‑temperature behavior: Published impedance ratios (Z at −25°C and −40°C vs +20°C) and 120 Hz characterization help designers evaluate performance across temperature extremes.
• RoHS compliance: Meets current RoHS requirements for environmentally restricted substances.
