LKS1K222MESZ

The LKS1K222MESZ is a snap-in terminal aluminum electrolytic capacitor designed for audio equipment and smaller-sized applications. It is a polarized, radial can snap-in package offering 2.2 mF capacitance at an 80 V rated voltage.

This component targets general-purpose electronic designs where compact, high-capacitance snap-in capacitors are required; it is RoHS compliant and intended to provide an upgrade path from smaller standard parts with an effect on tone quality when used in audio replacements.

Key Features

• Capacitance & Voltage — 2.2 mF capacitance rated at 80 V for applications requiring substantial energy storage in a compact form.
• Snap-in Radial Can Package — Snap-in mounting and radial can construction for secure chassis or PCB installation in power and audio assemblies.
• Audio-Focused Design — Specified for audio equipment and described as “smaller-sized” for use as a replacement to standard parts to achieve an effect on tone quality.
• Operating Range — Rated for operation from −40°C to +85°C to cover typical environmental conditions for indoor electronics.
• Endurance — Designed for 1000 hours at 85°C under rated voltage, meeting the series endurance specification for long-duration thermal stress.
• Low-Frequency Ripple Handling — Rated ripple current of 2.45 A at 120 Hz, suitable for low-frequency power filtering tasks.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20°C for predictable performance in filter and decoupling circuits.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Audio Equipment — Used as a replacement or upgrade capacitor in audio power supplies and signal circuits where the product is specified for audio equipment and noted to influence tone quality.
• General-Purpose Power Filtering — Provides bulk capacitance and ripple handling for general-purpose electronic power supplies requiring a polarized, high-capacitance snap-in solution.
• Electronics Assemblies with Snap-in Mounting — Fits applications that require a radial can, snap-in mounting style for mechanical stability in assemblies.

Unique Advantages

• Compact, high-capacitance package: 2.2 mF in a smaller-sized snap-in can enables space-conscious upgrades or replacements.
• Audio-oriented specification: Marketed for audio equipment and replacement use where an effect on tone quality is desired.
• Robust ripple capability: 2.45 A ripple current rating at 120 Hz supports low-frequency smoothing and decoupling in power circuits.
• Wide ambient tolerance: −40°C to +85°C operating range accommodates typical indoor electronic environments.
• Proven endurance: Rated for 1000 hours at 85°C under rated voltage, aligning with the series endurance expectations.
• Regulatory compliance: RoHS compliance supports use in designs requiring restricted-substance adherence.
