LKS1K392MESA

The LKS1K392MESA is an aluminum electrolytic capacitor in a snap-in terminal, smaller-sized package designed for audio equipment and general-purpose applications. It provides a 3.9 mF capacitance at an 80 V rated voltage with polarized construction and snap-in radial can mounting for secure panel or chassis installation.

Designed with audio applications in mind, this component is intended to aid tone quality improvement when replacing small standard parts, while offering predictable performance across a −40 °C to 85 °C operating range and compliance with RoHS (2011/65/EU, (EU)2015/863).

Key Features

• Core Electrical 3.9 mF capacitance with an 80 V rated voltage and ±20% tolerance, suitable for bulk energy storage and DC link applications where this value and voltage are required.
• Package & Mounting Snap-in terminal, radial can package provides a secure mechanical connection for chassis or panel mount assemblies while simplifying installation.
• Audio-Optimized Specified as “for audio equipment, smaller-sized” with an indicated effect on tone quality when replacing smaller standard components.
• Thermal and Endurance Rated for operation from −40 °C to 85 °C; endurance characteristics specify that after 1000 hours at 85 °C with rated voltage applied, capacitance change remains within ±20% and leakage/tan δ remain within series limits.
• Ripple Performance Rated ripple current of 3.3 A at 120 Hz, suitable for low-frequency ripple handling in power supply and audio circuits.
• Compliance RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulatory requirements for restricted substances.
• Physical Size Compact dimensions: L: 4.5 × D: 2.5 cm, enabling use where space is constrained.

Typical Applications

• Audio Equipment — Replacement and upgrade applications in audio circuits where the part’s audio-oriented specification and capacitance can affect tone quality and supply stability.
• Audio Power Amplifiers — Supply smoothing and energy storage in amplifier power rails requiring 3.9 mF at up to 80 V.
• General-Purpose Electronics — Bulk decoupling and energy buffering in industrial and consumer equipment that accept snap-in radial can capacitors.

Unique Advantages

• Audio-focused design: Specified for audio equipment with a note on tone-quality improvement when used as a replacement for smaller standard parts.
• High-voltage capability: 80 V rating gives designers headroom for higher-voltage audio and general-purpose power applications.
• Snap-in radial package: Facilitates secure mechanical mounting and straightforward installation in chassis or panel assemblies.
• Predictable endurance: Series endurance specification of 1000 hours at 85 °C with defined limits on capacitance change, tan δ, and leakage current supports reliable long-term performance planning.
• RoHS compliant: Meets current restricted-substance requirements for regulated markets.
