LKS1J123MESC

The LKS1J123MESC from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LKS series, optimized for audio equipment and general-purpose power filtering. It delivers high bulk capacitance in a compact snap-in radial can package, intended as a smaller-sized upgrade to standard parts to improve tone quality in audio applications.

Designed for embedded and board-level power systems, this polarized capacitor provides a combination of capacitance, voltage rating, and reliability characteristics suitable for smoothing, decoupling, and energy storage in low- to moderate-temperature environments.

Key Features

• Capacitance & Voltage — 12 mF (12,000 µF) rated at 63 V for substantial bulk energy storage and voltage handling in DC circuits.
• Package & Mounting — Snap-in radial can package for secure PCB mounting and simplified assembly in power supply and audio amplifier designs. Physical size: L: 4.5 × D: 3.5 cm.
• Temperature Range & Endurance — Operating temperature range of -40°C to +85°C with a rated lifetime of 1000 hours at 85°C when subjected to rated voltage.
• Ripple Performance — Rated ripple current of 4.75 A at 120 Hz, suitable for smoothing ripple in power circuits at typical line frequencies.
• Tolerance & Polarization — Capacitance tolerance of ±20% (at 120 Hz, 20°C); polarized design for DC applications.
• Leakage Current Specification — Leakage current specified as not more than 3√(C·V) µA after 5 minutes at 20°C, providing a quantifiable leakage expectation for design calculations.
• Environmental Compliance — Compliant with RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used as replacement or upgrade capacitors to improve tone quality and stabilize supply rails in amplifiers and audio power sections.
• Power Supply Filtering — Bulk smoothing and decoupling in linear and switch-mode power supplies where high capacitance and snap-in mounting are required.
