LKSN2392MESY

The LKSN2392MESY is a snap-in aluminum electrolytic capacitor from Nichicon’s LKS series, designed for audio equipment and general-purpose use. It combines a compact snap-in can package with polarized electrolytic performance tailored for applications where a smaller size and potential tone-quality improvement are desired.

This RoHS-compliant capacitor offers 3.9 mF capacitance at a 56 V rating, a wide operating temperature range, and endurance characteristics defined by the LKS series specification set.

Key Features

• Capacitance & Voltage — 3.9 mF rated capacitance with a 56 V nominal voltage rating, suitable for medium-voltage audio and general-purpose circuits.
• Tolerance & Polarization — Capacitance tolerance of ±20% and polarized construction for correct polarity installation in DC circuits.
• Package & Mounting — Radial, snap-in can package designed for snap-in mounting to simplify assembly in chassis and power-supply modules.
• Operating Temperature — Specified temperature range of −40°C to +85°C to cover typical commercial and audio-enclosure environments.
• Ripple Current — Rated ripple current of 2.6 A at 120 Hz, indicated for the part to support AC ripple conditions in power and audio applications.
• Endurance & Shelf Life — Endurance defined as 1000 hours at 85°C with post-test limits: capacitance within ±20%, tan δ within specified limits, and leakage current not exceeding initial value after the test.
• Leakage Current Specification — Leakage current after 5 minutes at rated voltage and 20°C is specified as not more than 3√CV (μA), where C is capacitance (μF) and V is voltage (V).
• RoHS Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Identification — Marked with silver color lettering on a black sleeve for quick visual identification.

Typical Applications

• Audio Equipment — Intended for use in audio circuits where replacement from a smaller standard product can produce a measurable change in tone quality.
• Power Supply Filtering — Snap-in package and rated ripple current make it suitable for bulk filtering and smoothing in medium-voltage power supplies.
• General-Purpose Industrial Electronics — Polarized electrolytic capacitor for decoupling, energy storage, and other general-purpose DC applications within the specified temperature range.

Unique Advantages

• Compact snap-in form factor: Radial snap-in can simplifies mechanical mounting and chassis integration compared with standard radial leaded devices.
• Audio-focused design: LKS series positioning and product notes indicate application in audio equipment with potential tone-quality improvements when replacing smaller standard parts.
• Defined endurance profile: 1000 hours at 85°C endurance specification provides clear reliability expectations for thermal stress and long-term use.
• Measurable leakage specification: Leakage current limit of 3√CV (μA) after 5 minutes at rated voltage gives a verifiable acceptance criterion for quality control.
• RoHS-compliant materials: Conforms to current RoHS requirements, supporting environmentally constrained product designs.
• Clear marking: Silver lettering on a black sleeve enables fast identification during assembly and inspection.
