LKS1K392MESB

The LKS1K392MESB is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose electronic applications. It delivers 3.9 mF capacitance at an 80 V rating in a smaller-sized, radial can snap-in package intended for replacement or upgrade use in audio systems.

Built for practical board or chassis installation, the LKS1K392MESB combines polarized electrolytic performance with a -40°C to +85°C operating range, RoHS compliance, and endurance characteristics specified for long-term operation at elevated temperature.

Key Features

• Capacitance & Voltage  3.9 mF nominal capacitance with an 80 V rated voltage suitable for higher-voltage power filtering and energy storage tasks.
• Polarized Electrolytic Construction  Polarized aluminum electrolytic capacitor with ±20% tolerance at 120 Hz, 20°C for predictable performance in DC-biased circuits.
• Ripple Current Capability  Rated ripple current of 3.3 A at 120 Hz to support AC ripple absorption in power supply and audio circuits.
• Temperature & Endurance  Operates from -40°C to +85°C and meets endurance requirements after 1000 hours at 85°C per the LKS series specification.
• Snap-in Radial Package  Snap-in terminal, radial can package for secure board or chassis mounting and straightforward replacement in existing assemblies.
• RoHS Compliant  Conforms to the RoHS directive (2011/65/EU, (EU)2015/863) for restricted hazardous substances compliance.

Typical Applications

• Audio Equipment  Intended for use in audio systems where replacement with a smaller-sized capacitor can improve tone quality as described in the product series notes.
• General-Purpose Electronic Equipment  Suitable for bulk filtering, smoothing, and energy storage tasks in general-purpose circuits that require a polarized electrolytic capacitor with snap-in mounting.
• Power Supply Filtering  Used to reduce ripple and stabilize DC rails in power supplies where 3.9 mF at 80 V and a 3.3 A ripple rating meet design needs.

Unique Advantages

• Designed for audio upgrades: Replacement from smaller standard products is noted to provide a tone-quality improvement in audio equipment.
• High working voltage: 80 V rating enables use in higher-voltage sections of power and audio circuits without stepping up to larger packages.
• Robust ripple handling: 3.3 A ripple current at 120 Hz supports demanding ripple suppression requirements.
• Wide operating temperature: -40°C to +85°C range and 1000-hour endurance at 85°C provide stable performance over typical equipment environments.
• Snap-in mounting convenience: Radial, snap-in can simplifies installation and replacement in assemblies designed for snap-in capacitors.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for commercial and professional products.
