Overview of LKSH2392MESB – Snap-in Aluminum Electrolytic Capacitor for Audio Equipment

The LKSH2392MESB from Nichicon is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and general-purpose electronic circuits. This smaller-sized radial can is intended as a drop-in upgrade to improve tone quality when replacing smaller standard capacitors, while providing a robust electrical profile for power filtering and decoupling.

With a nominal capacitance of 3.9 mF at 71 V, snap-in mounting, and RoHS compliance, the LKSH2392MESB targets designers seeking a compact, serviceable electrolytic solution with defined ripple handling and endurance characteristics.

Key Features

  • Capacitance & Voltage — 3.9 mF nominal capacitance rated at 71 V, suitable for energy storage and smoothing in power circuits.
  • Package & Mounting — Snap-in radial can package for secure board retention and straightforward assembly into chassis or PCBs.
  • Polarized Electrolytic — Polarized design for DC filtering and bulk energy applications.
  • Electrical Performance — Rated ripple current of 3.05 A at 120 Hz supports effective AC ripple handling in power supply applications.
  • Temperature & Endurance — Operating temperature range of −40°C to +85°C with an endurance specification of 1000 hours at 85°C under rated voltage.
  • Tolerance — Capacitance tolerance ±20% at 120 Hz, 20°C for predictable circuit behavior.
  • Compact Footprint — Size approximately 3 cm × 3 cm, offering a smaller form factor for space-constrained designs.
  • Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

  • Audio Equipment — Used in power supply and coupling/decoupling roles where its smaller size and specified electrical characteristics can contribute to perceived tone quality improvements.
  • General-Purpose Power Filtering — Bulk smoothing and ripple reduction in DC power rails for consumer and professional electronics.
  • Replacement/Upgrade Projects — Direct replacement of smaller standard capacitors to improve circuit performance in existing designs.

Unique Advantages

  • Designed for audio upgrades — Marketed specifically for audio equipment with the intent to improve tone quality when replacing smaller standard parts.
  • Strong ripple handling — 3.05 A ripple current rating at 120 Hz enables reliable filtering in applications with measurable AC ripple.
  • Compact snap-in form — Radial snap-in can and ~3 cm × 3 cm footprint facilitate secure mounting while saving board or chassis space.
  • Defined endurance — 1000 hours at 85°C under rated voltage provides a documented lifetime expectation for thermal stress conditions.
  • Regulatory compliance — RoHS-compliant construction supports restricted substance requirements in many markets.
