LKS2A122MESZ

The LKS2A122MESZ from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LKS series, designed for audio equipment and general-purpose electronic use. Its smaller-sized snap-in can construction aims to provide a tone-quality improvement when replacing small standard parts while delivering reliable filtering and energy storage performance.

As part of the LKS series, this capacitor follows the series' rated voltage range (25–100 V) and capacitance range (680–33,000 μF) characteristics. It is RoHS compliant and built for through-hole snap-in mounting in PCB assemblies.

Key Features

• Capacitance & Rated Voltage — 1.2 mF capacitance at 100 V, suitable for higher-voltage audio and general-purpose circuits.
• Snap-in Radial Can Package — Snap In mounting type in a radial, can-style package for secure mechanical retention on PC boards.
• Audio-focused, Smaller-sized Design — Marketed for audio equipment with a smaller form factor and an indicated effect of tone-quality improvement when replacing small standard products.
• Operating Temperature & Endurance — Rated for -40 °C to +85 °C with an endurance specification of 1000 hours at 85 °C.
• Ripple Current (120 Hz) — Rated ripple current of 2.15 A at 120 Hz to support power smoothing duties in AC-rectified circuits.
• Leakage Current Specification — Leakage current after 5 minutes at 20 °C is specified as not more than 3√CV (μA), where C is capacitance (μF) and V is voltage (V), per the datasheet.
• Polarized Device — Electrolytic, polarized capacitor intended for correct polarity installation.
• RoHS Compliant — Manufactured in compliance with the RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Physical Size — Body dimensions: L: 3.5 × D: 2.2 cm, allowing space-efficient placement in assemblies.

Typical Applications

• Audio Equipment — Intended for audio circuits where replacement with a smaller standard product can contribute to perceived tone-quality improvement.
• General-Purpose Electronics — Suitable for general-purpose filtering and energy storage needs within its rated voltage and temperature ranges.
• PCB Assemblies Requiring Snap-In Mounting — Designed for secure snap-in installation in through-hole boards where radial can capacitors are preferred.

Unique Advantages

• Designed for audio quality improvement — The LKS series notes an effect on tone quality when replacing smaller standard products, making this part suitable for audio-focused upgrades.
• Secure snap-in mounting — Snap In terminal and radial can package provide robust mechanical retention for through-hole assemblies.
• Rated ripple handling — 2.15 A ripple current at 120 Hz supports smoothing in rectified AC circuits common in audio power supplies.
• Wide operating temperature — -40 °C to +85 °C rating supports a broad range of environmental conditions encountered in consumer and professional equipment.
• Endurance and shelf-life standards — Datasheet endurance: specified performance after 1000 hours at 85 °C and a shelf-life condition defined for 1000 hours at 85 °C with subsequent voltage treatment.
• Standards-based leakage spec — Leakage current specified quantitatively (≤ 3√CV μA after 5 minutes at 20 °C), enabling predictable designs for low-leakage requirements.
