LKG1V392MESBBK

The LKG1V392MESBBK is an aluminum electrolytic capacitor in a snap‑in radial can package, optimized for high‑grade audio equipment. It belongs to Nichicon’s LKG series and is specified for audio applications where high tone quality and fidelity are priorities.

Key attributes include a 3.9 mF (3900 µF) capacitance at 35 V rated voltage, low loss behavior (tan δ = 0.3 at 120 Hz, 20°C), and design elements and grade coding aligned with the LKG TYPE‑II (Gold Tune) family.

Key Features

• Audio‑grade design  Designed specifically for high‑grade and HD audio equipment to prioritize high fidelity and tone quality as described in the LKG series.
• Electrical performance  3.9 mF (3900 µF) rated capacitance with a 35 V voltage rating and capacitance tolerance of ±20% (at 120 Hz, 20°C). Tangent of loss angle (tan δ) is specified at 0.3 (measurement frequency: 120 Hz, 20°C).
• Ripple capability  Ripple current rating of 2.4 A at 120 Hz, supporting demanding audio supply conditions within the stated limits.
• Package & mounting  Snap‑in radial can (φ30 × 25L / L: 2.5 cm × D: 3.0 cm) with polarized terminals for secure PCB mounting and mechanical stability.
• Operating environment  Rated for operation from −40°C to +85°C with a specified lifetime of 1000 hours at 85°C.
• Leakage and reliability  Leakage current limit after 5 minutes at 20°C is specified as not more than 3√(C·V) µA (C: µF, V: V), consistent with LKG series endurance and shelf‑life criteria.
• Regulatory  RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑grade audio amplifiers  Used where capacitor characteristics contribute to tone quality and stable supply behavior for audio stages.
• HD Audio playback systems  Suited to systems demanding high tonal fidelity and consistent performance over the audio frequency range.
• Professional and studio equipment  Appropriate for mixers, preamps, and other professional gear that specify audio‑focused capacitor characteristics.

Unique Advantages

• Purpose‑built for audio fidelity  Part of the LKG audio series and specified for high tone quality, supporting design goals for HD audio reproduction.
• Measurable low loss  Specified tan δ = 0.3 at 120 Hz (20°C) gives designers a quantifiable loss figure to use in circuit modeling and selection.
• Compact snap‑in form factor  φ30 × 25L radial can with snap‑in terminals enables robust board mounting in compact audio assemblies.
• Temperature and endurance ratings  −40°C to +85°C operating range with a 1000‑hour rating at 85°C provides a defined reliability envelope for system lifetime planning.
• Clear leakage specification  Leakage current limit defined by the 3√(C·V) rule simplifies verification and acceptance testing.
• RoHS compliance  Meets current RoHS requirements for regulated materials.
