LKSH2392MESC

The LKSH2392MESC from Nichicon is a snap-in terminal, aluminum electrolytic capacitor in the LKS series designed for audio equipment and general-purpose electronic applications. It provides 3.9 mF (3900 μF) capacitance at a 71 V rated voltage in a compact radial, can-style snap-in package.

Engineered for applications that benefit from higher tone quality and reliable bulk capacitance, this polarized capacitor combines a compact footprint with defined performance: ±20% capacitance tolerance, -40 °C to +85 °C operating range, RoHS compliance, and a specified ripple current rating at 120 Hz.

Key Features

• Capacitance & Voltage — 3.9 mF (3900 μF) nominal capacitance with a 71 V rated voltage for bulk energy storage and filtering where higher voltage headroom is required.
• Snap-in Radial Package — Snap-in terminal type in a radial, can-style package for secure board-mounted installation in power assemblies and chassis-mounted designs.
• Compact Size — Physical dimensions approximately L: 2.5 cm × D: 3.5 cm, delivering substantial capacitance in a smaller footprint.
• Electrical Tolerance — Capacitance tolerance of ±20% (measured at 120 Hz, 20 °C) to aid predictable circuit behavior in design margins.
• Ripple Current Capability — Rated ripple current of 3.05 A at 120 Hz to support AC ripple handling in power supply and audio circuits.
• Operating Range & Endurance — Specified to operate from -40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C.
• Polarized Electrolytic — Polarized construction suitable for DC applications requiring electrolytic bulk capacitance.
• RoHS Compliant — Conforms to RoHS directive requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used in audio power supplies and signal circuits where replacing smaller standard capacitors can produce a measurable improvement in tone quality.
• General-Purpose Electronics — Provides bulk capacitance and smoothing in a wide range of electronic equipment requiring a polarized, high-capacitance snap-in capacitor.
• Snap-in Power Assemblies — Suited to board- or chassis-mounted power modules that use snap-in terminal capacitors for secure mechanical and electrical connection.

Unique Advantages

• High Bulk Capacitance in a Compact Can — 3.9 mF in a small radial snap-in package reduces space while maintaining energy storage for smoothing and decoupling.
• Designed for Audio Quality — Marketed for audio equipment with documented benefits when replacing smaller standard parts to improve tone quality.
• Defined Thermal Endurance — Rated for continuous operation up to 85 °C with a 1000-hour endurance specification, providing predictable aging and reliability data for design planning.
• Clear Electrical Limits — Specified ripple current (3.05 A at 120 Hz) and ±20% tolerance support precise design trade-offs in power and audio circuits.
• Regulatory Compliance — RoHS compliance supports regulatory and environmental requirements for modern electronic products.
